Reaction: NONE
Acknowledge: NONE
Cause: The selected service/maintenance interval for this motor was reached.
Alarm value (r2124, interpret decimal):
Motor data set number.
See also: p0650 (Actual motor operating hours), p0651 (Motor operating hours maintenance interval)
Remedy: carry out service/maintenance and reset the service/maintenance interval (p0651).
F01662 Error internal communications
Reaction: OFF2
Acknowledge: POWER ON
Cause: A module-internal communication error has occurred.

Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect configuring telegram.
Alarm value (r2124, interpret decimal):
50: Syntax error.
52: Too many data words for input or output. Max. 8 words are permitted.
53: Uneven number of bytes for input or output.
Remedy: Check the bus configuration on the master and slave sides.
A01901 (F) PROFIBUS: Parameterizing telegram error
Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect parameterizing telegram.
Alarm value (r2124, interpret decimal):

Acknowledge: IMMEDIATELY
Cause: The reception of setpoints from the fieldbus interface has been interrupted, because
- the bus connection was interrupted, or
- the communication peer was switched off.
CU230-2P DP:
- the PROFIBUS master was set to the STOP state.
See also: p2040 (Fieldbus interface monitoring time), p2047 (PROFIBUS additional monitoring time)
Remedy: Ensure bus connection has been established and switch on communication peer.
CU230-2P HVAC:
- if required, adapt p2040.
CU230-2P DP:
- set the PROFIBUS master to the RUN state.
- slave redundancy: For operation on a Y link, it must be ensured that "DP alarm mode = DPV1" is set in the slave
parameterization.
