Explanation of the parameters
Parameterization of MOVIPRO
®
P864 PWM fre-
quency CFC
Setting range: 4 / 8 / 16 kHz
P864 can be used in "CFC" and "Servo" operating mode 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.
P87x Process data description
P870/P871/P872
Setpoint descrip-
tion PO1/PO2/PO3
P870/P871/P872 define the content of the process output data words PO1/PO2/PO3.
This is necessary so that the power section can allocate the appropriate setpoints.
The following PO assignments are available:
See the "Fieldbus unit profile with parameter list" manual for detailed explanations.
P873/P874/P875
Actual value
description PI1/
PI2/PI3
P873/P874/P875 define the content of the process input data words PI1/PI2/PI3. This is
necessary so MOVIPRO
®
can allocate the appropriate actual values.
The following PI assignments are available:
