4. Description of Operating Functions
Ŷ Positioning start (CSTR)
Upon detecting a rise edge (0 o1) of this signal, the controller will read the target position number as a binary
code consisting of six bits from PC1 to PC32 (position no. specification register), and execute positioning to the
target position of the corresponding position data.
Before issuing a start command, all operation data such as the target position and speed must be set in the
position table using the PC or teaching pendant.
If this command is issued when home return operation has not been performed yet after the power input (the
HEND output signal is OFF), the controller will automatically perform home return operation before positioning to
the target position.
Ŷ Moving (MOVE)
This signal is output while the servo is ON and the actuator is moving (also during home return, push & hold
operation or jogging).
Use the MOVE signal together with the PEND signal to allow the PLC to determine the actuator status.

during push & hold operation that the work is being contacted as well as when positioning is completed.
Ŷ Command position number (PC1  PC32)
When a movement command is effected upon 0 o 1 of the CSTR signal, the six-bit binary code consisting of
signals PC1 to PC32 will be read as the command position number.
Ŷ Completed position number (PM1  PM32)
