3.2.27.2 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.
Angular trimming
Adds a setpoint at DFSET−A−TRIM (see C0536/3) to the angle setpoint. The rotor position with
respect to the setpoint can be changed in either direction by the defined number of increments (the
drive is leading or lagging). The angle is trimmed within a range of ±32767 increments (corresponds
to ±1/2 revolution). Every analog signal can be used as a source.
l The input is made in increments (one revolution corresponds to 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
The angular offset (C0252) adds a constant angular offset to the setpoint of the drive.
Speed−proportional angle adjustment
With speed−proportional angle adjustment the angle lags or leads with rising speed.
l Enter a corresponding adjustment value in increments in C0253.
l The set angle adjustment is reached at 15000 rpm of the drive (linear relationship).
