Motor control (MCTRL)
V/f characteristic control (VFCplus)
Note!
V
min
boost is automatically calculated by the motor parameter identification
using the data specified on the motor nameplate so that a no-load current of
approx. 0.8 I
rated motor
results at the slip frequency of the machine.
V/f control (VFCplus + encoder)
If V/f control (VFCplus + encoder) is selected, we recommend a decidedly lower
V
min
boost:
• In this case, select a V
min
boost which ensures that approx. 50 % of the rated
motor current flows at slip frequency when the motor is idling.
