Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
VECTOR: NONE (OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F: IMMEDIATELY
A05053 (F) Parallel circuit: Inadmissible DC link voltage dissymmetry
Drive object: A_INF, B_INF, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The deviation of the DC link voltage measured values exceeds the alarm threshold specified in p7011.
Remedy: - inhibit the pulses of the faulted power unit (p7001).
- check the DC link connecting cables.
- the DC link voltage measurement is incorrect and must be calibrated or renewed.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
VECTOR: NONE (OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F: IMMEDIATELY
A05054 Parallel circuit: Power unit de-activated
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: For the drive object involved, fewer power unit components connected in parallel are active than exist in the target
topology. Operation is only possible at reduced power (power de-rating).
Remedy: Re-activate the de-activated power unit components.

nents), p0897 (Parking axis selection)
F05055 Power circuit: Power units with different code numbers
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code numbers of the power units do not match.
Fault value (r0949, interpret decimal):
Parameter in which the first different power unit code number was detected.
Remedy: For parallel circuit configurations, only power units with identical power unit data may be used.
F05056 Parallel circuit: Power unit EPROM versions differ
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The EEPROM versions of the power units do not match.
Fault value (r0949, interpret decimal):
Parameter in which the first different version number was detected.
Remedy: For parallel circuit configurations, only power units with identical EEPROM versions may be used.
F05057 Parallel circuit: Power unit firmware versions differ
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The firmware versions of the power modules connected in parallel do not match.
Fault value (r0949, interpret decimal):
Parameter in which the first different version number was detected.
Remedy: For parallel circuit configurations, only power modules with identical firmware versions may be used.
