Detection for failure of the power removal function
Monitoring the input status of the HWTO1 input and the HWTO2 input and the output status of the EDM output
relative to the inputs can detect the failure of the power removal function.
When the power removal function is properly operated, the combination of each signal is any of the following.
Combinations other than the table indicate the power removal function of the driver is in a failure state.
HWTO1 input HWTO2 input EDM output
ON ON
OFF

If only one of the HWTO1 input and the HWTO2 input is ON or OFF, the external device or wiring has failed. Check the
cause and take a measure immediately. At this time, the EDM output is in an OFF state and the motor puts into a
non-excitation state.
• Do not release the power removal function when the EDM output is in an OFF state.
• If the driver or external device is failed or an error in wirings occurs, check the cause and take a
measure immediately.

ETO-CLR input
If the ETO-CLR input is turned ON after both the HWTO1 and HWTO2 inputs are turned ON to release the power
removal function, the motor puts into an excitation state.

ETO-MON output
If the HWTO1 input or the HWTO2 input is turned OFF when the “HWTO mode selection” parameter is set to “0: Alarm
is not present,” the ETO-MON output is turned ON. If the motor is excited with the ETO-CLR input after both the
HWTO1 and HWTO2 inputs are turned ON, the ETO-MON output is turned OFF.
