3 Functions
♦ In order that the motor can immediately establish a torque after an ON
command, the magnetizing time P0346, determined with the quick
commissioning, may not be reset. This is the reason that parameter P0346
should be checked for the weight equalization.
Typical magnetizing times for 4-pole 1LA7 motors are:
♦ The min. frequency P1080 should approximately correspond to the rated
motor slip (P1080
♦ In addition, the voltage boost should be adapted:
