Input signals
„ Coordinate preset signals
This signal is used to preset the mechanical home or the electrical home.
z P-PRESET input
Turning the P-PRESET input ON can rewrite the command position and the feedback position to the value set in the
"Preset position" parameter.
At the same time, they are written to the non-volatile memory.
However, position preset cannot be executed while the motor is being operated.
Even if the motor is being stopped, position preset cannot be executed while the TLC output is ON.
The INFO-PR-REQ output is being ON while position preset is executed. When the position preset is completed, the
HOME-END output is turned ON.

z EL-PRST input
The coordinate system is switched to that with the electrical home as the home while the EL-PRST input is ON.
The coordinate position when the EL-PRST input is turned from OFF to ON is the electrical home, and the motor
operates in the electrical home coordinate system.
Turning the EL-PRST input OFF returns to the coordinate system with the mechanical home as the home.
Setting a different home (electrical home) from the mechanical home can control the motor in a different coordinate
temporarily.

Coordinate
• If the EL-PRST input is turned ON during operation, the command position and the feedback
position at that time is set to the electrical home coordinates. However, the target position of the
operation being executed remains at the position in the mechanical home coordinate system.
Execute the operation in the electrical home coordinate system after stopping the operation.
• High-speed return-to-home operation cannot be executed while the EL-PRST input is ON.
