Figure 7-23 Torque pre-control for VECTOR control

Parameters for the function diagrams for torque pre-control

p0341[0...n] Motor moment of inertia / MotID M_mom inert

Setting of the motor moment of inertia (no load).

This parameter is automatically preset for motors from the motor list (p0301). When a motor from the list is selected, this parameter cannot be changed (write protection). To remove the write protection, the information in p0300 must be observed.

p0342[0...n] Ratio between the total moment of inertia and that of the motor

Sets the ratio between the total moment of inertia/mass (load + motor) and the intrinsic motor moment of inertia/mass (no load).

The product p0341 * p0342 is taken into account when automatically calculating the speed controller (VECTOR).

p1455[0...n] CI: Speed controller P gain adaptation signal / n_reg Adapt_sig Kp

Sets the source for the adaptation signal for additional adaptation of the speed controller P gain. A possible source is the relative moment of inertia of the INCO block.

r1493 Moment of inertia, total

Indication of the total moment of inertia before evaluation by scaling using p1497.

SERVO: r1493 = (p0341 * p0342) + p1498

VECTOR: r1493 = (p0341 * p0342) *p1496

p1496[0...n] Acceleration pre-control scaling / a_before scaling (VECTOR)

Sets the scaling for the acceleration pre-control of the speed/velocity controller.
