[5-17] Voltage boost at linear/square-law V/f characteristic
Short overview: Parameters for voltage boost
Tip!
For magnetising the motor, consider a sufficient time from the controller enable to the
start of the speed ramp function generator.
• The bigger the motor the longer the time required for magnetisation. A motor with a
power of 90 kW requires up to 2 seconds.
