5.6.3 Control structure The next step is to select the “Control structure” parameter. This is located on the
main menu under:
07=CONTROL
Possible settings for the control structure are as follows:
- Frequency control
- Speed control without encoder
- Speed control with (incremental) encoder
- Torque control without encoder (with higher level speed control)
- Torque control with (incremental) encoder and higher level speed control
5.6.4 Speed adjustment/ The following parameters are determined as speed details regardless of the control
speed limit structure selected. They are also to be adjusted, even for frequency control in rpm,
and also apply to the torque control structure.
The speed limit (in rpm) indicates the maximum speed of the drive taking all additional
demands into account. The corresponding maximum inverter output frequency is
displayed automatically. This parameter is adjusted on the main menu under
"02 = Application parameter".
The max. and min. speeds are also determined by the motor potentiometer parameter
settings.
5.6.5 Field weakening The following parameters under "02 = Application parameter" must be set for
operation with field weakening:
- Increase the speed limit
- Increase the max. speed motor potentiometer
- Increase ref. overspeed
Protection level 1 must be selected for increasing the ref. overspeed parameter. This
is possible on the main menu under "09 = Password".
