A07920 Drive: Torque/speed too low
Reaction: NONE
Acknowledge: NONE
Cause: For p2193 = 1:
The torque deviates from the torque/speed envelope characteristic (too low).
For p2193 = 2:
The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too low).
See also: p2181 (Load monitoring response)
Remedy: - check the connection between the motor and load.
- adapt the parameterization corresponding to the load.
A07921 Drive: Torque/speed too high
Reaction: NONE
Acknowledge: NONE
Cause: For p2193 = 1:
The torque deviates from the torque/speed envelope characteristic (too high).
For p2193 = 2:
The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too high).
Remedy: Check the connection between the motor and load.
Adapt the parameterization according to the load.
A07922 Drive: Torque/speed out of tolerance
Reaction: NONE
Acknowledge: NONE
Cause: For p2193 = 1:
The torque deviates from the torque/speed envelope characteristic.
For p2193 = 2:
The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169).
Remedy: Check the connection between the motor and load.
Adapt the parameterization according to the load.
F07923 Drive: Torque/speed too low
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: For p2193 = 1:
The torque deviates from the torque/speed envelope characteristic (too low).
For p2193 = 2:
The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too low).
Remedy: Check the connection between the motor and load.
Adapt the parameterization according to the load.
F07924 Drive: Torque/speed too high
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: For p2193 = 1:
The torque deviates from the torque/speed envelope characteristic (too high).
For p2193 = 2:
The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too high).
Remedy: Check the connection between the motor and load.
Adapt the parameterization according to the load.
