For the torque/power reduction, internally only positive setpoints are effective. For a negative
analog setpoint at terminal 24.x/20.x, an inversion function must be switched–in.

P0620:
... defines up to which maximum voltage, a reduction can be made.
P1243:8
... defines up to which maximum torque or power a reduction can be made.
The data is a percentage with the following reference:
Reference for torque: P1230 (1st torque limit)
Reference for power: P1235 (1st power limit)

with an input voltage
of 0 V to 5 V, the
torque/power can be
reduced from
50 % to 0 %, referred to
P1230/P1235
