enabled
• Not enabled: The controller ignores the Cos phi set point analogue input
and Modbus input.
• Enabled: During reactive power sharing, the controller uses the Cos phi
set point analogue input or Modbus input as the cos phi set point.
Cos phi set point
source
• External
• External -> Off
External
• External: The controller uses the Cos phi set point analogue input or
Modbus input.
• External -> Off: If the Cos phi set point analogue input and/or Modbus
input fails (that is, when the input is outside the configured scale), then the
controller ignores the input.
INFO
If an analogue input is configured, the Modbus value for the external offset will reflect the analogue input value. The
Modbus external offset cannot be configured until the analogue input for the external offset is cleared.
6.4.3 External communication using Modbus
If you want to send set point values over Modbus, instead of using the controller internal set points, then you must configure and
activate the set point function on the controller. When the function is active, the controller ignores the internal set points configured in
the parameters and uses the set points it receives over Modbus.
Inputs
Configure the inputs under Configure > Input/output. Select the hardware module, then select the input to configure.
INFO
These inputs are only visible if a regulation output (either relay or analogue) is configured.
