Transmitting A Power Setpoint
It is possible to transmit a power setpoint value via the CANopen protocol. Prerequisite for
the use of a power setpoint via an interface is the configuration of the power setpoint
sources with AnalogManager "AM ActPower SP1 [kW]"
ActPower SP2 [kW]"
, "AM ActPower SP3 [kW]"
or "AM ActPower SP4
[kW]"
.
for detailed information).
The respective power setpoint source is to be configured to "05.56 Interface P setp [kW]".
Please note that the type of the power setpoint (Steady, Import, or Export) must also be
defined by parameter "Load setpoint 1", (
), parameter "Load setpoint 2" (
for), parameter "Load setpoint 3" (
) or parameter "Load setpoint 4" (
).
Two different methods to transmit a power setpoint via CANopen are detailed below.
These are "Transmitting a power setpoint via RPDO" and "Transmitting a power setpoint
via default SDO communication channel". The advantages and the disadvantages of
these two methods are as follows.
RPDO
Default SDO communication channel
Classical communication for CANopen devices
Configuration process
One message
Two messages
No validation of the received answer
Validation answer, if message has been received by the
unit
Only working in operational mode
May take longer in case of communication with two
messages

RPDO
Configure CAN interface 1
CANopen Master (parameter
) must be enabled, if there is no PLC taking over
the master function.
