Power supply

The NCi-E interface draws its power from the NCi-6 interface and the encoder communications channel.
The supplies to the NCi-E interface are protected by a 0.5 A resettable fuse. To reset a fuse, remove the associated power supply, then identify and rectify the cause of the fault.
The nominal current drawn by the NCi-E from the NCi-6 supply is as follows:

• 15 mA @ 24 Vdc
• 20 mA @ 12 Vdc

NOTE: To disconnect the NCi-E power supply from the NCi-6, remove the wires from the terminals. To disconnect the NCi-E power supply from the encoder communications channel, remove the 9-way D-type connector.

Interface status LEDs

Two LEDs are fitted on the front of the NCi-E interface. These provide the operator with a visual indication of the M-code A status and encoder communications status.

M-code A status LED

The LED indicates the status of M-code A to the operator. M-code A activates and deactivates voltage readings from the NC4, NC4+ or NC4+ Blue unit.
When M-code A is inactive, the NCi-E outputs zeros. When M-code A is active, the NCi-E outputs the voltage readings from the NC4, NC4+ or NC4+ Blue unit.

Encoder communications status LED
Indicates the status of the communications between the NCi-E interface and the encoder communications channel of the CNC machine controller.

Standard DIN rail mounting

Alternative mounting

Connecting the NCi-E interface to the NCi-6 interface and CNC machine controller

9-way NCi-E connector CN1
NCi-E connector CN1 is used to connect the NCi-E interface to the NCi-6 interface, and M-code A to the CNC machine controller.

9-way D-type NCi-E connector CN2
NCi-E connector CN2 is used to connect the NCi-E interface to the CNC machine tool encoder communications input.

Configuring the NCi-E interface filter settings

The filter settings are applied using the switches in switch bank SW1. The SW1 switch locations which correspond to ON and OFF settings are shown on the label.
CAUTION: Only qualified persons should adjust switches on the interface.

SW1-1| SW1-1| SW1-1| SW1-1|
---|---|---|---|---
800| 400| 200| 100| Total Hz
ON| ON| ON| ON| 150
ON| ON| ON| OFF| 250
ON| ON| OFF| ON| 350
ON| ON| OFF| OFF| 450
ON| OFF| ON| ON| 550
ON| OFF| ON| OFF| 650
ON| OFF| OFF| ON| 750
ON| OFF| OFF| OFF| 850
OFF| ON| ON| ON| 950
OFF| ON| ON| OFF| 1050
OFF| ON| OFF| ON| 1150
OFF| ON| OFF| OFF| 1250
OFF| OFF| ON| ON| 1350
OFF| OFF| ON| OFF| 1450
OFF| OFF| OFF| ON| 1550
OFF| OFF| OFF| OFF| 1650

Renishaw recommends that all switches are switched to the ON position to reduce the likelihood of machine alarms. To increase the bandwidth and enable higher scan velocities, switches can be switched to the OFF position.

Configuring the M-code polarity
The M-code polarity is set using the switches in switch bank SW2. The M-code polarity determines whether the input responds to an active-high or active-low signal. 0 Vdc is used to set the M-code to “Low” and 11 Vdc to 30 Vdc is used to set the M-code to “High”. SW2 is located inside the NCi-E interface housing. The removable cover must be detached to access switch bank SW2 (see page 2-1, “NCi-E basics”, for further information).

Setting the M-code polarity

Switch| On| Off
1| Not used| –| –
2| M-code A active| Low| High
3| Not used| –| –
4| Not used| –| –
