Identifier Description
601 Remote F setpoint
It is possible to transmit a voltage setpoint value via the CANopen
protocol. Prerequisite for the use of a voltage setpoint via an inter‐
face is the configuration of the voltage setpoint source (parameter
5618 Ä p. 288 for voltage setpoint 1 source or parameter
5619 Ä p. 288 for voltage setpoint 2 source).
Ä Chapter 4.5.12.5 "Voltage Control" on page 286 for
Refer to
detailed information.
The respective voltage setpoint source is to be configured to 05.09
"Interface volt.setp.".
Two different methods to transmit a voltage setpoint setpoint via
CANopen are detailed below.
These are "Transmitting a voltage setpoint via RPDO" and "Trans‐
mitting a voltage setpoint via default SDO communication channel".
The advantages and the disadvantages of these two methods are
as follows.
