8.1.2 No Communication with the Drive
If there is no communication with the drive, proceed with the following checks:
Check 1: Is the cabling correct?
Check that the cables are connected to the correct terminals as shown in the
diagram.
Pin no. Terminal Colour Name
1 V- Black GND
2 CAN_L Blue CAN LOW
3 Drain (bare) Screen
4 CAN_H White CAN HIGH
5 V+ Red +24 V
Check 2: Is the 24V network voltage applied?
Check 3: Is the correct EDS file installed?
Download the correct EDS file from http://www.geelectrical.com/drives.
Check 4: Is the bus connection terminated at both ends?
If not, terminate the bus connection with termination resistors at the initial and final nodes, as shown in the following diagram. Termination is performed between
terminal 2 (CAN_L) and 4 (CAN_H) with a resistor: 121 Ohm, 1% metal film, ¼ Watt.
