It is possible to transmit a frequency setpoint value via the CAN‐
open protocol. Prerequisite for the use of a frequency setpoint via
an interface is the configuration of the frequency setpoint source
(parameter 5518 Ä p. 273
parameter 5519 Ä p. 274
Ä Chapter 4.5.12.1 "Frequency Control" on page 271 for detailed
information.
The respective frequency setpoint source is to be configured to
05.03 "Interface freq.setp.".
Two different methods to transmit a frequency setpoint via CAN‐
open are detailed below.
These are "Transmitting a frequency setpoint via RPDO" and
"Transmitting a frequency setpoint via default SDO communication
channel". The advantages and the disadvantages of these two
methods are as follows.
