Hall only Mode

Parameters for Hall only operation can be set on the "Hall only" menu page. Hall only operation consists of two phases which are parameterized via the parameter SLJSWITCH (switchover threshold):

Phase 1: low output frequency (speed <SLJSWITCH)

In this phase, the amplifier works in U/F mode. Magnetization current is generated via the "ID setpoint" (MIMR) parameter and the voltage vector rotated at the desired frequency. If the motor does not turn in this phase despite the specification of a speed setpoint, either the MIMR value is too small or the acceleration ramp SLACCMAX is too steep.

Phase 2: high output frequency (speed ≥ SLJSWITCH)

If the switchover threshold SLJSWITCH is exceeded, the U/F mode is exited after the switchover time SLTSWITCH and the regular feedback operation is activated.The motor phase parameter only takes effect in this phase. The settings of the speed controller are also active.

The "Phase actual" field shows the operating phase of the amplifier.
