CANOPEN CONNECTORS
Dual RJ-45 connectors that accept standard Ethernet cables are provided for CAN bus connectivity. Pins are wired-through so that
drives can be daisy-chained and controlled with a single connection to the user's CAN interface. A CAN terminator should be placed
in the last drive in the chain. The R52-NK connector kit provides a D-Sub adapter that plugs into a CAN controller and has an RJ-45
socket that accepts the Ethernet cable.
SPK-NK CAN CONNECTOR KIT
The kit contains the SPK-CV adapter that converts the
CAN interface D-Sub 9M connector to an RJ-45 Ethernet
cable socket, plus a 10 ft (3 m) cable and terminator.
Both connector pin-outs conform to the CiA DR-303-1
specification.
INDICATORS (LEDS)
The AMP LED on J9 shows the operational state of the R52. The STATUS LED on J9 shows the state of the CANopen NMT (Network
Management) state-machine in the drive. LEDs on J10 show activity on the CANopen network. Details on the NMT state-machine can
be found in the CANopen Programmers Manual, §3.1:
AMP LED
A single bi-color LED gives the state of the R52 by changing color, and either blinking or remaining solid.
The possible color and blink combinations are:
• Green/Solid:
• Green/Slow-Blinking: Drive OK but NOT-enabled. Will change to Green/Solid when enabled.
• Green/Fast-Blinking: Positive or Negative limit switch active. Drive will only move in direction not inhibited by limit switch.
• Red/Solid:
• Red/Blinking:
Drive Fault conditions. Faults are programmable to be either transient or latching:
• Over or under-voltage
• Motor over-temperature
• Encoder +5 Vdc fault
• Short-circuits from output to ground

STATUS LED
A single bi-color LED gives the state of the NMT state-machine by changing color, and either blinking or remaining solid.
The possible color and blink combinations are:
RUN (GREEN)
• Off
• Blinking
• Single-flash
• On
ERROR (RED)
• Off
• Blinking
• Single Flash
• Double Flash
• Triple Flash
• On
ACT LED
• Flashing indicates the R52 is sending/receiving data via the CAN port
