Explanation of the parameters
Parameters
• OFF: MOVIDRIVE
®
automatically reduces the set output frequency (down to mini-
mum 4 kHz) when there is a high level of thermal load on the output stage to avoid
a switch-off with the "Unit utilization" error.
P864 PWM
frequency CFC
Setting range: 4 / 8 / 16 kHz
P864 can be used in CFC and SERVO operating modes to set the switching frequency
at the inverter output for parameter set 1. The cycle frequency is set to a fixed value and
is not automatically reduced with high unit utilization.

P872 Setpoint
description PO1 /
PO2 / PO3
P870/P871/P872 define the content of the process output data words PO1/PO2/PO3.
This is necessary so MOVIDRIVE
®
can allocate the appropriate setpoints.
The following PO assignments are available:
See "Fieldbus unit profile with parameter list" manual for detailed explanations.

description PI1 /
PI2 / PI3 P873/P874/P875 define the content of the process input data words PI1/PI2/PI3. This is
necessary so MOVIDRIVE
®
can allocate the appropriate actual values.
