Further torque feedforward control options

[11-40] Feedforward control with parameterised starting torque

Application example:

In the case of a hoist drive, the load is always known. For an optimum behaviour a torque

proportional to the load and additionally 10 Nm as a constant feedforward control value should be

loaded into the speed controller.

• As a constant feedforward control value the starting torque 1 is used (C02586

="10 Nm",

C02588

="0", and BRK_bStartingTorque2 =FALSE).

• Via the input BRK_dnTorqueAdd_n the torque is specified proportional to the load.

• Via the input BRK_dnTorqueAdd_n an

additional feedforward control value can

be defined.

Note:

The input is read out if the brake receives a

release signal, e.g. when

BRK_bReleaseBrake =TRUE.
