Names and functions

The drawing below shows names and functions of main parts.

The drawing below shows names and functions of main
parts

Description of terminals

Name	Function	Electrical specification	Internal circuits
NETA (A)	LONWORKS transmission data / reception data	No polarity

NETB (B)
SHIELD (S)| LONWORKS communication shield terminal.| This terminal is grounded through 10Mohm resistor.

Service pin

Service pin function causes the node to propagate the service message over the network so that the network controller finds the node.
This option unit has the software service pin function that operates the procedure shown in below.

Set the inverter parameter to 1.
Set the inverter parameter to 0.

Just after the parameter is set to “0”, LONWORKS option unit propagates the service message over the network.

Service LED

Service LED indicates the node condition.

Service LED

No	Phenomenon	Problem & Solutions
1	Although the inverter is turned on, LED remains OFF.	Check the connection

between the inverter and the LONWORKS option unit. If abnormality is not found after checking, it needs to be repaired.
2| LED continues to be ON after the inverter is turned on.

3

| LED is ON then OFF when the inverter is turned on, and it continues to be ON.| Internal application program is abnormal.
If the same indication appears after resetting the power, it needs to be repaired.
4| LED flashes every 0.5 second.
5| LED flashes every 1 second.| This is a normal action of the “Unconfigured” device. If the device is not “Unconfigured”, Internal application program is broken. It needs to be repaired.
6| LED momentarily turns ON then continues to be OFF.| When the node is in “Configured” status, LED momentarily turns ON when the inverter is turned on. Then the LED continues to be OFF for some seconds. The node indicates “Configured” status that means the normal condition.
–| Flicker of LED (Approximately 10Hz to 30Hz)| CPU is abnormal. It needs to be repaired.
–| LED turns ON while activating service pin.| This is normal action while activating service pin.

Status LED

It displays node status with green color.

Status LED

Fault LED

It displays fault with red color.

LED state	Description
OFF	LONWORKS option unit has no fault.
ON	Hardware or software fault of the LONWORKS option unit

error occurs. If the same indication appears after resetting the power, it needs to be repaired.

Installation and Setup

Installation method

Install the LONWORKS communication option to VF-PS1 as follows.

Turn off input power of VF-PS1 and wait for at least 15 minutes and then check that the CHARGE lamp on VF-PS1 is no longer lit.
Securing the option to the inverter
a) Insert a flat-blade screwdriver in each of the two holes at the upper part of the front panel, release the panel mounting tab by pushing the screwdriver down, and remove the front panel cover.
b) Fix the option into the inverter by fixing the tabs on the lower side of the option into the slots at the lower part of the inverter front panel.

Install this option into the front panel side when it is used together with the IO card option.
c) Make sure the option is securely attached to the inverter. Then, check whether the plastic bosses on the inverter case have fixed in the holes at the upper and lower parts of the option.
d) Insert the tabs at the lower part of the front cover into the slots at the lower part of the inverter to attach the front cover to the inverter.
e) Stick the enclosed “LED name label” on the option LED indicator part of a front cover.

VF-PS1 communication parameters

VF-PS1 parameters referring to below table are available.

Title	Function	Description
Command mode selection	While LONWORKS communication option is installed

into VF-PS1 and configured to network, the network command and setpoint are prior to VF-PS1 LOCAL mode is prior to it.
| Setpoint mode selection
| Option parameter| Service pin function (see section 2.2).
| Operation at network error| Set the behavior when “Receive heart beat timer” overflow occurred (see function manual).
| Option reset| Set 1 when resetting the option unit.

Network cable connection

Connect the LONWORKS network cable to LONWORKS communication option as follows.

Cable selection (a twisted pair cable with shield)
Use Level 4/22 AWG cable for the network cable.
– Recommended cable
Manufacturer: SWCC SHOWA CABLE SYSTEMS CO.,LTD.
Model name: LW221S, 22AWG, 1P, With shield, Standard 300m/reel
Use 0.75mm2 wire for grounding to the earth terminal (G/E) of the board.
Terminal blocks
Manufacturer: PHOENIX CONTACT
Model name: MSTB 2,5/3-ST-5.08

• Communication terminal “NETA (A)”, “NETB (B)”
Connect LONWORKS transmission/reception data cable.
Polarity of the communication terminals NETA and NETB does not have to be considered.
• Shield terminal “SHIELD (S)”
Connect the shield of network cable. Refer to next section for grounding.
Connection
Cable sheath should be peeled off by about 7mm.
For wiring work, use a flat blade screwdriver with a 0.6mm thick and 3.5mm width blade.
Tightening torque for the terminal block is 0.5Nm.

Network configuration

Make up the network as follows.

Transmission/reception signals (NETA, NETB)
Make up the communication path by connecting all transmission/reception data cables (No polarity).
Grounding the shield of cable (SHIELD)
Connect the all shield lines of network cable. Ground through as a total resistance of network cable shield is about 470k ohm, so that static electricity does not increase (at the point where it separated from the power ground of inverters or motors).
Termination resistor (Please refer to “3.5. Termination resistor”)
Only one terminal resistor is needed for the segment of the free topology. It can also be placed wherever it is on the free topology segments. (2 termination resistors in case of Bus topology)
Network cable length (for recommended cable usage)
Free-Topology: device-to-device distance is 400m or less, total wire length is 500m or less
Bus-Topology: total wire length is 1400m or less, stub length is 3m or less.
Connection image

Network configuration is shown in the figures below. This LONWORKS communication option has TP/FT-10 channel type transceiver. The free topology wiring supported by the TP/FT-10 channel type accommodates bus, star, loop, or several combinations of these topologies shown in below.

The free topology wiring example

N.B.: Do not connect the SHIELD terminal to the power ground of inverters or other units.
Keep the network cables 20cm or more separate from the power cables to prevent from malfunctioning due to electromagnetic noise.

Termination resistor

Terminate the network bus with about 52.3ohm impedance to minimize the reflections. There are two choices for the termination.

Free Topology Network Segment
Only one termination and may be placed anywhere on the free topology segment.
RC network (Following figure), with R1 = 52.3ohm +/-1%, 1/8W
Doubly Terminated Bus Topology Segment
It is necessary to terminate at both ends of a twisted pair bus.
RC network (Following figure), with R1 = 105ohm +/-1%, 1/8W
