Input of response value for the tolerance band of the PLC status message nset < nact (see
also MD 241). The tolerance band of the nset = nact response threshold can be defined in
machine data MD 27.

Active
at once
Input of P gain (Kp) for the speed controller. The speed controller has a PI function which can
be set separately for eight gear stages.
Note:
A speed controller adaptation can be implemented only for gear stage 1 (see MD 203).
