Features
m Maximum frequency: double nominal frequency
m Minimum frequency: is limited by load inertia and actual remaining flux
m High DC link voltage (> 560 V) and a low stator resistance can lead to wrong detection
of motor operation conditions
Adjustment aid
m For a successful catch on fly of the motor, the exact knowledge of the motor parame-
ters is inevitable, especially deadtime compensation as well as rotor and stator resis-
tance. Make sure, that all steps described in chapter ZSensorless control– from page
655 have been completed during commissioning.
m If a DC link overvoltage error occurs during catch operation, parameterize Z167.3–
Catch demagnetization time
m If a overcurrent error occurs during catch operation, parameterize Z167.3– Catch de-
magnetization time
m During catch operation, the actual speed value Z18.22– settles to the actual rotor
speed. Overshoots of over 30% might occur. Take this into account to parameterize
the overspeed limits.
Required parameters
m Catch enable Z167.1–
