8400 StateLine, HighLine and TopLine: FW version = 13.00.00.00
Response of the new version?
Also in the V/f motor control types with encoder C006=7+9, the motor phase error monitoring does not respond without any reason anymore.
Which products are affected?
8400 StateLine, HighLine and TopLine: 02.00.00.00 ≥ FW version ≤ 13.00.00.00
What happens?
The motor phase error monitoring responds directly after controller enable although no error is pending.
When does the problem occur?
The response may occur sporadically in the VFCplus motor control types: V/f linear with encoder and VFCplus: V/f quadr. with encoder (C006=7+9)
Diagnostics options?Check whether the monitoring function also responds before operation if the motor control type is set to V/f without encoder for purposes of testing. If the error does not occur anymore then, we are presumably dealing with the response described.
Short-term measures/recommendations?
The motor phase error monitoring can be deactivated with the setting C2866/2=0.
Evaluation:
With the Lenze setting, the monitoring function is not active. A motor phase error during operation can still be monitored after deactivating the monitoring function before operation.
