Bytes 9 and 10: Input AIN 1

Byte 9 = high byte, byte 10 = low byte.
Byte 9 and byte 10 transmit the value of the first additional free analogue current
input of the Modbus interface. The start and end values can be set at the AC via
push buttons and display. (For operation, please refer to the respective operation
instructions for the actuator.)
If the measuring values are 0.3 mA below the initial value, a signal loss is indicated.
The value is transmitted in per mil (value: 0

Bytes 11 and 12: Torque

Byte 11 = high byte, byte 12 = low byte.
Bytes 11 and 12 transmit the current torque of the actuator (only if an MWG is installed
in the actuator).
The value transmitted is the current torque in percent or per mil of the nominal actuator
torque.
The value is transmitted in per mil (value: 0
The value 1,000 corresponds to 127,0 % torque in direction OPEN.
The value 500 is the torque zero point.
The value 0 corresponds to 127,0 % torque in direction CLOSE.

Byte 13: Not ready REMOTE 1

Value Description
1 Wrong operation command
Indicates that several operation commands were received simultaneously via Modbus
(e.g. Remote OPEN and Remote CLOSE simultaneously or Remote CLOSE/Remote
OPEN and Remote SETPOINT simultaneously) or that the max. value for a setpoint
position has been exceeded (setpoint position > 1,000).
0 Operation commands are ok.
1 Selector switch is in position Local control (LOCAL) or 0 (OFF).
0 Selector switch is in position Remote control (REMOTE).
