5.3.1 Control Signals and Control Data
To operate the actuator via serial communication, the internal 16-bit memory (Modbus registers and statuses) of
the controller must be written/read. The key signals and symbols used in these operations are explained below.
For details, refer to the Operation Manual for Serial Communication Protocol.

040AH 5 STP Pause command
The “0” status of this bit indicates a normal
condition. When this bit changes to “1,” the
actuator will pause (decelerate to a stop).

command
Home return operation will be performed at
the “0” o “1” edge of this bit.
040CH 3 CSTP Positioning start
The “0” status of this bit indicates a normal
condition. The actuator will start moving to

(Note) The meanings of [Common], [POS specification] and [Numerical specification] in the “Register” field are
explained below:
x [Common]: The register is used in both the position number specification mode and the
numerical specification mode.
x [POS specification]: The register is used in the position number specification mode.
x [Numerical specification]: The register is used in the numerical specification mode.
