RTLC20 and FASTRACK application

1. Thoroughly clean and degrease the substrate and allow it to dry.
   For FASTRACK location a ledge, separate straight edge(s) or dowels can be used.
   Check alignment of ledge/separate straight edge(s) concerning g axis of motion (‘RTLC20/FASTRACK installation drawing’,).

2. Before sticking FASTRACK to the substrate bend the centre section upwards slightly using a small pair of pliers.

3. Remove the backing liner and stick it to the substrate, locating it against the ledge/separate straight edge(s) or dowels. Ensure complete adhesion to the substrate by applying firm finger pressure along the length of the FASTRACK from the centre outwards towards each end using a lint-free cloth if required.
   NOTE: Allow the FASTRACK a minimum of 20 minutes to adhere before removing the centre section.

4. Engage the centre section removal tool and with consistent forward pressure remove the centre section. If the ledge method or similar is used then the appropriate side panel on the removal tool will need to be removed as shown.

   • IMPORTANT: Wear suitable protective gloves whilst carrying out this procedure to avoid the risk of cuts.

5. Slide RTLC20 scale into the FASTRACK ensuring the scale is fed under the projections as shown. Scale can be installed manually by either pulling or pushing it through the FASTRACK carrier. Alternatively, use the optional scale installation tool as shown for easy installation.
   NOTE: For instructions on how to use the scale installation tool, download the RTL* scale installation tool (A-9589-0420) User guide (Renishaw part no. M-9589-9101) from the website at www.renishaw.com/tonicdownloads.
   IMPORTANT: If manually installing the scale using fingers, suitable gloves should be worn to protect against injury from sharp edges.

6. Scale datum

   • The datum clamp fixes the RTLC20 scale rigidly to the substrate at the location chosen.

   • The metrology of the system may be compromised if the datum clamp is not used.

   • The datum clamp does not need to be fitted adjacent to a reference mark.

   • It can be positioned anywhere along the axis, depending on the customer’s requirements.
     Adhesive clamp

   • Using the dispensing tip apply Loctite 435 between the scale and FASTRACK so it wicks underneath adjacent to the user-selected datum location as shown.

   • NOTE: The drawing shows the scale datum adjacent to the chosen reference mark. NOTE:
     Only apply Loctite 435 in these gaps to ensure the best bond. Loctite 435 will wick under the scale to lock it to the substrate.
     **Mechanical clamp

• Additional screws available (pack of 25, A-9584-2047).
  NOTE: When the reference mark and the datum clamp are aligned as shown, the reference output will be positionally repeatable concerning the substrate.
  **

  7. Optional: fix self-adhesive end covers ensuring a gap of at least 1 mm between the end of the scale and the end cover.
  8. Clean FASTRACK and scale using a lint-free cloth.

Reference mark selector and limit magnet installation

• IMPORTANT: Allow 24 hours after RTLC20 / FASTRACK application before fitting magnets.
• For accuracy and ease of positioning of reference mark selector and limit magnets, the applicator tool should be used. The magnet should be attached to the applicator tool as shown below and outlined with the outer edge of the
• FASTRACK. Limit magnets can be positioned at any user-defined location along the FASTRACK, but the reference mark selector magnet should be positioned adjacent to the chosen IN-TRAC reference mark as shown below.
• As the TONiC readhead passes the reference mark selector magnet or limit switch magnet, a force of up to 0.2 N is generated between the magnet and the readhead. The design of the bracket should be sufficiently stiff so that it can tolerate such force without distorting. Following the scale installation instructions will prevent this magnetic force from disturbing the scale.

Limit trigger point
The limit output is nominally asserted when the redhead limit switch sensor passes the limit magnet leading edge but can trigger up to 3 mm before that edge (‘RTLC20/FASTRACK installation drawing’, page 6).

NOTES

• Reference and limit magnets may creep when influenced by magnetic materials nearby. In such cases, they should be held in place using an additional fillet of epoxy glue or similar along the outer edge of the magnet assembly.
• The reference mark selector and limit actuator locations are correct for the read-head installation shown.
• All limit and reference selector magnets should be aligned with the outer edges of the FASTRACK.
• The reference mark selector magnet is only required for ‘Customer selectable reference mark’ redheads. For more information refer to the TONiC™ encoder system data sheet (Renishaw part no. L-9517-9337).
• External magnetic fields greater than 6mT, in the vicinity of the read-head, may cause false activation of the limit and reference sensors.

TONiC quick-start guide

• This section is a quick-start guide to installing a TONiC system.
• More detailed information on installing the system is contained in the following sections of the installation guide.

INSTALLATION

NOTE:
If calibration fails, restore factory defaults by pressing and holding the CAL button whilst switching on (‘Restoring factory defaults’, page 17). Then repeat the installation and calibration routine.

System connection

• Approved ESD precautions must be followed at all times during readhead and interface electrical connections.
• The redhead is connected to the Ti/TD interface via a small, rugged PCB connector to allow for easy feed-through during installation.

Connecting the redhead

1. Remove the cover plate as shown (2 × M2.5 hex head screws).
2. Taking care not to touch the pins, plug the connector into the socket in the interface, ensuring correct orientation as shown. Press-fit the PCB connector to ensure a good connection.
3. Refit the cover plate ensuring the cable ferrule is located in the recess on the inside and no wires are trapped under the cover plate.
   NOTE: The tightening torque should be between 0.25 Nm and 0.4 Nm .

Disconnecting the redhead

1. Remove the cover plate on the interface (2 × M2.5 hex head screws).
2. Gently lever the connector PCB (on the end of the cable) out of the socket. Do not pull the cable to remove the connector.
3. Place the connector in an anti-static bag.
4. Refit the cover plate.

Readhead mounting and alignment
Mounting brackets
The bracket must have a flat mounting surface and should provide adjustment to enable conformance to the installation tolerances, allow adjustment to the height of the redhead, and be sufficiently stiff to prevent deflection or vibration of the read-head during operation.
Readhead set-up
Ensure that the scale, readhead optical window and mounting face are clean and free from obstructions.

NOTE:
When cleaning the readhead and scale apply cleaning fluid sparingly, do not soak.

To set the nominal ride height, place the black read-head spacer with the aperture under the optical centre of the readhead to allow normal LED function during the set-up procedure. Adjust the read-head to maximise the signal strength along the full axis of travel to achieve a Green set-up LED on the readhead (> 70% signal). If a digital Ti/TD interface is used, aim for a Blue LED on the interface.

NOTE:
The redhead should be installed and set up with the AGC switched off (CAL LED off). When reinstalling, the factory defaults should be restored (‘Restoring factory defaults’, page 17).

• Momentary output status only, while fault condition remains.
• The alarm may result in an axis position error, re-datum to continue.

See the TONiC encoder system Datasheet (Renishaw part no. L-9517-9337) for interface configuration details. This can be downloaded from our website at www.renishaw.com/tonicdownloads and is also available from your local Renishaw representative.

System calibration

Calibration is an essential operation that completes the readhead set-up, with the optimum incremental and reference mark signal settings stored in the read- head’s non-volatile memory.

Before system calibration

• Clean the scale and readhead optical window (contamination around the reference mark may result in reference mark dephasing).
• If re-installing, restore factory defaults (‘Restoring factory defaults’, page 17).
• Ensure Automatic Gain Control (AGC) is switched off (CAL LED on redhead is not illuminated).
• Maximise the signal strength along the full axis of travel.

NOTES:

• CAL routine maximum speed < 100 mm/s (all Ti / TD interface models).
• TD interface can be calibrated in either resolution.

Step 1 – Incremental signal calibration

• Press the CAL button on the end of the interface for < 2 seconds using a 2 mm Allen key or similar tool.
  WARNING! Activating the CAL switch requires only 2.5 N force. Applying excess force may permanently damage the switch.

• The CAL LED will now periodically single-flash to indicate that it is in incremental signal calibration routine.

• Move the redhead along the axis, ensuring you do not pass the selected reference mark until the CAL LED starts double-flashing. This indicates the incremental signal is now calibrated and the new settings are stored in the readhead memory.

• The system is now ready for reference mark phasing.

• For systems without reference marks, go to ‘Calibration routine manual exit’.

• If the system does not automatically enter the reference mark phasing stage (no double-flashing of
  the CAL LED) the calibration of the incremental signals has failed. After ensuring failure is not due to overspeed (> 100 mm/s), exit the calibration routine, restore factory defaults (‘Restoring factory defaults’, page 17) and check the read-head installation and system cleanliness before repeating the calibration routine.

Step 2 – Reference mark phasing

• Move the redhead back and forth over the selected reference mark until the CAL LED stops flashing and remains off. The reference mark is now phased.
  NOTE: Only the chosen reference mark that has been used in the calibration routine is guaranteed to remain phased.

• The system automatically exits the CAL routine and is ready for operation.

• If the CAL LED continues double-flashing after repeatedly passing the chosen reference mark it is not being detected.

  • Ensure that the correct readhead configuration is being used. Redheads can either output all reference marks or only output a reference mark where a reference selector magnet is fitted depending on the options chosen when ordering.
  • Check reference mark selector magnet is fitted in the correct location relative to read-head orientation (‘RTLC20/FASTRACK installation drawing’, page 6).

Calibration routine manual exit
To exit the calibration routine at any stage, press the CAL button. The CAL button will stop flashing.

Restoring factory defaults
When reinstalling the system or in the case of continued calibration failure, factory defaults should be restored.

To restore factory defaults:

• Switch the system off.
• Press and hold the CAL button whilst switching the system on. The CAL LED on the read-head will flash several times, indicating that the factory defaults have been restored.
• Release the CAL button.
• Check ‘Readhead mounting and alignment’, page 15, and recalibrate the system (‘System calibration’, page 16).

NOTE: System must be re-calibrated after restoring factory defaults.

Enabling /disabling AGC
AGC can be switched on or off via the interface.

• Press and hold the CAL button on the interface for > 3 seconds to switch AGC on or off. The CAL LED on the read-head will be illuminated when AGC is active.

NOTE: The system must be calibrated before switching AGC on (‘System calibration’, page 16).

NOTE: TD maximum speeds are resolution-dependent as defined above.

Electrical connections

Grounding and shielding

IMPORTANT:
The outer shield must be connected to the machine earth (Field Ground). The inner shield * must be connected to 0 V at receiving electronics only. Care should be taken to ensure that the inner and outer shields are insulated from each other. If the inner and outer shields are connected, this will cause a short between 0 V and earth, which could cause electrical noise issues.

NOTE:
The maximum cable length between the read-head and Ti/TD interface is 10 m.

For UHV there is no inner shield to be connected.

Remote CAL operation (analogue versions only)
All Ti/TD interfaces include a push-button switch to enable CAL/AGC features. However, remote operation of the CAL/AGC is possible via pin 14 of analogue Ti0000 interfaces. For applications where no interface is used, remote operation of CAL/AGC is essential.

TD interface resolution switching
Connect pin 10 to 0 V to switch to lower resolution.

Recommended signal termination

Digital outputs

• Standard RS422A line receiver circuitry.
• Capacitors are recommended for improved noise immunity.

Single-ended alarm signal termination (Ti options A, B, C, D)

Limit output (no limits on TD interfaces)

• Select R so the maximum current does not exceed 20 mA.
• Alternatively, use a suitable relay or opto-isolator.

Specifications

Output specifications

Digital output signals
Form – Square wave differential line driver to EIA RS422A (except limits P and Q)

Incremental † 2 channels A and B in quadrature (90° phase shifted)

NOTE:
Select a ‘standard’ or ‘wide’ reference at time of order, to match the requirements of the controller being used. Wide reference mark not available on Ti0004 interfaces.

Limits Open collector output, asynchronous pulse

Digital Ti interfaces only

NOTE: No limits on TD interfaces. P limit becomes E+ for options E, F, G, and H.

Alarm † Asynchronous pulse

Line driven

Alarm asserted when:

• Signal amplitude < 20% or > 135%The redheaded speed is too high for reliable operation.
• • E− output only for Ti options A, B, C, and D.

or 3-state alarm
Differentially transmitted signals force an open circuit for > 15 ms when alarm conditions are valid.

**Set-up ***

Set-up signal voltage proportional to incremental signal amplitude.

• Inverse signals are not shown for clarity.

Analogue output signals

Incremental
2 channels V1 and V2 differential sinusoids in quadrature centred on 1.65 V (90° phase shifted).

Limits Open collector output, asynchronous pulse

Ti0000 interface only

NOTE:
Ti0000 interface contains a transistor to invert the redhead’s ‘active low’ signal to give an ‘active high’ output.

Set-up

• Between 50% and 70% signal level, VX is a duty cycle.
• Time spent at 3.3 V increases with incremental signal level.
• At > 70% signal level VX is nominal 3.3 V.
  • Set-up signals as shown are not present during the calibration routine.

General specifications

Power supply| 5 V ±10%| Readhead only < 100 mA T103x with Ti0000 < 100 mA T103x with Ti0004 – Ti20KD

and TD4000 – TD0040 < 200 mA

NOTE: Current consumption figures refer to unterminated systems.

For digital outputs, a further 25 mA per channel pair (e.g., A+, A−) will be drawn when terminated with 120R.

For analogue outputs, a further 20 mA in total will be drawn

when terminated with 120R.
