9.2.10 Inverter operation in CANopen communication
This chapter describes the inverter’s operation by using the CANopen communication.
There are the following two ways to run the inverter:
1. Operation according to CANopen’s drive profile (DSP 402)
2. Operation according to the inverter function code S06

604B - vl set-point factor
Modifies the resolution and specified range of
the speed settings.
ARRAY RW
As for the inverter’s operation, PDO No.2 is useful which can send both Controlword and speed
command at the same time.
