Processing of correction values

Speed trimming

This is used to add correction values, e.g. by a superimposed control loop. This enables the drive to
accelerate or decelerate.

l

Adds an analog value at DFSET−N−TRIM (see C0537) to the speed setpoint.

l

Adds a speed value at DFSET−N−TRIM2 (see C1258) to the speed setpoint.

– The speed trimming via this input is more precise.

Phase trimming

This adds a setpoint at DFSET−A−TRIM (see C0536/3) to the phase setpoint and changes the rotor
position to the setpoint with the number of increments provided in either direction (drive is leading
or lagging). The phase is trimmed within a range of ±32767 increments (

¢ ±1/2 revolution). Every

analog signal can be used as a source.

l

The entry is made in increments (one revolution

¢ 65536 increments).

l

When analog values are entered, 100% correspond to 1/4 revolution = 16384 increments.

l

Extension of the setting range with a multiplier under C0529.

Angular offset

Addition of a fixed phase offset under C0252 to the setpoint of the drive.

Speed−proportional phase setting

Leading or lagging of the phase with rising speed.

l

Enter a suitable setting in increments under code C0253.

l

The set phase offset is reached at 15000 rpm of the drive (linear relationship).
