SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets whether the voltage is continuously increased during the magnetizing phase (p1350 = 1, On) or whether it
jumps directly to the voltage boost (p1350 = 0, Off).
Value: 0: OFF
1: ON
Note: The settings for this parameter have the following advantages and disadvantages:
0 = off (jump directly to voltage boost)
Advantage: Flux is established quickly -> torque is quickly available
Disadvantage: The motor can move while it is being magnetized
1 = on (voltage is continually established)
Advantage: The motor is unlikely to rotate
Disadvantage: The flux is established slower -> torque is available later
Description: Sets the configuration for the closed-loop speed control.
Note: Re bit 01:
When the bit is set, the I component of the speed controller is kept when changing into the open-loop controlled
mode.
