Alarm of HWTO input circuit error
If a time after either the HWTO1 input or the HWTO2 input is turned OFF until the other input is turned OFF exceeds
the value set in the “HWTO delay time of checking dual system” parameter, an alarm will be generated. (HWTO input
circuit error, alarm code 53h)
At this time, the PWR/ALM LED blinks twice in red repeatedly.

ETO reset ineffective
period
Sets a time to disable the ETO-CLR input if the motor is
excited by the ETO-CLR input after both the HWTO1 and
HWTO2 inputs are turned ON. The motor cannot be
excited until the time set in this parameter is exceeded
even if the ETO-CLR input is turned ON.
