can be used to specify which setpoint or actual value is to be

transferred. The meaning of the setpoint or actual values is set in the frequency inverter via

parameters (P543) - (P548) for SK 500E and via parameters (P543[-01]-[-03]) or (P546[-01]

- [-03]) for SK 200E.

Control data, profile DS301 with USS State Machine:

In order to be able to control the frequency inverter, the CANopen status must first be set to “Operational”

After switching on, the frequency inverter is in “Switch-on disabled” status. It has to be switched to "Ready for

switch-on" status using a control command. To do so, the control word “0x047E” must be transmitted. The

PDO telegram then has the following structure:

Byte 1 2 3 4

ID=204 7E

hex

The drive should then run at 50% of its maximum frequency. For this purpose, the control words “0x047F” and

“0x2000” must be transmitted as setpoints:
