Indicator light flashing patterns
Each indicator light has the following flashing patterns:
•
Blinking: The on and off pattern with a frequency of approximately 2.5 Hz. On for approximately 200 ms followed
by off for approximately 200 ms.
•
Single flash: 1 short flash (approximately 200 ms) followed by a long off phase (approximately 1000 ms).
•
Double flash: A sequence of 2 short flashes (approximately 200 ms each), separated by an off phase (approximately
200 ms). This sequence is followed by a long off phase (approximately 1000 ms).
8.2.2 Check 2: Error Counters
8 8
Check the values of the TEC and REC in
parameter 10-05 Readout Transmit Error Counter and
parameter 10-06 Readout Receive Error Counter.
8.2.3 Check 3: Is the Cabling Correct?
Check that the cables are connected to the correct
terminals.

8.2.5 Check 5: Is the bus connection
terminated at both ends?
If the bus connection is not terminated at both ends,
terminate the bus connection with termination resistors at
the initial and final nodes. Termination is performed
between terminal 2 (CAN_L) and 4 (CAN_H) with a resistor:
•
121 Ω.
•
1% metal film.
•
¼ W.
If the frequency converter with CANopen control cassette
is at the end of the fieldbus line, turn on the CAN
termination switch to activate the on-board termination
resistor. In this case an external resistor is not required. To
see the termination switch, refer to Illustration 8.1. By
default, the switch is off.
