Overview of Alarms
Remedy: For a flying changeover between operation with and without encoder with pole position
identification after POWER ON or commissioning (p0010 not equal to zero) enable the
pulses once at zero speed. This means that the pole position identification routine is
carried-out and the result is available for operation.
208000 <location>TB: +/-15 V power supply faulted
Reaction: NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Terminal board 30 detects an incorrect internal power supply voltage.
Fault value (r0949, decimal):
0: Error when testing the monitoring circuit.
1: Fault in normal operation.
Remedy: - replace terminal board 30.
- replace control unit.
208010 <location>TB: Analog-digital converter
Reaction: NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The analog/digital converter on terminal board 30 has not supplied any converted data.
Remedy: - check the power supply.
- replace terminal board 30.
208500 <location>COMM BOARD: Monitoring time, configuration expired
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The monitoring time for the configuration has expired.
Fault value (r0949, decimal):
0: The transfer of the send-configuration data has been exceeded (time).
1: The transfer of the receive-configuration data has been exceeded (time).
Remedy: Check communication line.
208501 <location>COMM BOARD: Monitoring time, process data expired
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The set monitoring time expired while transferring process data via COMM BOARD.
See also: p2040
Remedy: - check communications link.
- check the set monitoring time if the error persists.

208502 <location>COMM BOARD: Monitoring time, sign-of-life expired
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The monitoring time for the sign-of-life counter has expired.
Remedy: Check communication line.
208510 <location>COMM BOARD: send configuration data not valid.
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: COMM BOARD did not accept the send-configuration data.
