Supported Modbus functions (ser-
vices)
Commands and signals of the Modbus TCP/IP interface
CW, CCW, MPV position, RESET, EMERGENCY operation command, enable local controls, Interlock
CW/CCW
Process representation output
(command signals)
●
Actual position value
●
Actual torque value, requires magnetic limit and torque transmitter (MWG) in actuator
●
Selector switch in position LOCAL/REMOTE
●
Running indication (directional)
●
Torque switches CW/CCW
●
MPV positions
●
Manual operation by handwheel or via local controls
●
Analogue (2) and digital (4) customer inputs
Process representation input (feed-
back signals)
●
Motor protection tripped
●
Torque switch tripped
●
One phase missing
●
Failure of analogue customer inputs
Process representation input (fault
signals)
The behaviour of the actuator is programmable:
●
Stop in current position
●
Execute travel in CW or CCW
●
Travel to any intermediate position
●
Execute last received operation command
