P0618: This defines the input voltage at which the maximum useful motor speed is reached.
P1401:8: The parameter specifies the maximum motor useful speed, and represents the refer-
ence value for P0618.
The standard value is pre–assigned for the hardware configuration depending on the
motor used.
P0618
Example:
P0618 = 9
P1401:8 = 2000
––> at 9 V, the motor reaches a speed
of 2000 RPM

P1401:8
Note:
The maximum useful motor speed, set using P1401:8 is taken into account when calculating
the speed setpoint. This means that P1401:8 acts as a speed limit.
This is independent of whether the setpoint is entered via a terminal or PROFIBUS.

This parameter value is added to the torque setpoint or force setpoint (SLM).
Note:
This allows a weight equalization to be set.

For the torque/power reduction via terminal 24.x/20.x (refer to Chapter 6.6.4), this parameter
can be used to make adjustments.
