A07089 Changing over units: Function module activation is blocked because the units have
been changed over
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: An attempt was made to activate a function module. This is not permissible if the units have already been changed
over.
See also: p0100 (IEC/NEMA mot stds), p0505 (Selecting the system of units)
Remedy: Restore units that have been changed over to the factory setting.
A07092 Drive: moment of inertia estimator still not ready
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The moment of inertia estimator still has no valid values.
The acceleration cannot be calculated.
The moment of inertia estimator is ready, if the frictional values (p1563, p1564) as well as the moment of inertia value
(p1493) have been determined (r1407.26 = 1).
Remedy: Repeat the operation when the moment of inertia estimator is ready (r1407.26 = 1).
A07094 General parameter limit violation
Message class: Hardware/software error (1)
Reaction: NONE
Acknowledge: NONE
Cause: As a result of the violation of a parameter limit, the parameter value was automatically corrected.
Minimum limit violated --> parameter is set to the minimum value.
Maximum limit violated --> parameter is set to the maximum value.
Alarm value (r2124, interpret decimal):
Parameter number, whose value had to be adapted.
Remedy: Check the adapted parameter values and if required correct.
A07200 Drive: Master control ON command present
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The ON/OFF1 command is present (no 0 signal).
The command is either influenced via binector input p0840 (current CDS) or control word bit 0 via the master control.
Remedy: Switch the signal via binector input p0840 (current CDS) or control word bit 0 via the master control to 0.
F07220 (N, A) Drive: Master control by PLC missing
Message class: Communication error to the higher-level control system (9)
Reaction: OFF1 (NONE, OFF2, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: The "master control by PLC" signal was missing in operation.
- interconnection of the binector input for "master control by PLC" is incorrect (p0854).
- the higher-level control has withdrawn the "master control by PLC" signal.
- data transfer via the fieldbus (master/drive) was interrupted.
Remedy: - check the interconnection of the binector input for "master control by PLC" (p0854).
- check the "master control by PLC" signal and, if required, switch in.
- check the data transfer via the fieldbus (master/drive).
Note:
If the drive should continue to operate after withdrawing "master control by PLC" then fault response must be
parameterized to NONE or the message type should be parameterized as alarm.
