GE AF-650 GP - Intermediate Section Functionality

Select the motor frequency value from the motor nameplate data. If a value different from 50 Hz or 60
Hz is selected, it is necessary to adapt the load independent settings in par. H-50 Motor Magnetisation at
Zero Speed to par. H-53 Model Shift Frequency. For 87 Hz operation with 230/400 V motors, set the name-
plate data for 230 V/50 Hz. Adapt par. F-17 Motor Speed High Limit [RPM] and par. F-53 Maximum
Reference to the 87 Hz application.
F-05 Motor Rated Voltage
Range: Function:
500. V* [10. - 1000. V] Enter the nominal motor voltage according to the motor nameplate data. The default value corresponds
to the nominal rated output of the unit.
F-07 Accel Time 1
Range: Function:
3.00 s* [0.01 - 3600.00 s] Enter the accel time, i.e. the acceleration time from 0 RPM to the synchronous motor speed n
S
. Choose a
accel time such that the output current does not exceed the current limit in par. F-43 Current Limit during
ramping. The value 0.00 corresponds to 0.01 sec. in speed mode. See decel time in par. F-08 Decel Time
1.

F-08 Decel Time 1
Range: Function:
3.00 s* [0.01 - 3600.00 s] Enter the decel time, i.e. the deceleration time from the synchronous motor speed n
s
to 0 RPM. Choose a
decel time such that no over-voltage arises in the inverter due to regenerative operation of the motor,
and such that the generated current does not exceed the current limit set in par. F-43 Current Limit. The
value 0.00 corresponds to 0.01 s in speed mode. See accel time in par. F-07 Accel Time 1.

F-09 Torque Boost
Range: Function:
100 %* [0 - 300 %] Enter the % value to compensate voltage in relation to load when the motor is running at low speed and
obtain the optimum U/f characteristic. The motor size determines the frequency range within which this
parameter is active.
