Return from power removal status
If both the HWTO1 and HWTO2 inputs are turned ON, the power removal status is released. At this time, the motor
remains in a non-excitation state.
To excite the motor, turn the ETO-CLR input ON (initial value: enabled at the ON edge). When the ETO-CLR input is
turned ON, the status of the motor and driver will be as follows.
• The ETO-MON output is OFF.
• The READY output, the PLS-RDY output, and the MBC output are ON.
• The PWR/ALM LED is lit in green.
• When an electromagnetic brake motor is used, the electromagnetic brake is in a state of releasing the motor
output shaft.
• Check the equipment is in a safe state before returning the driver from the power removal status.
• Even if either the HWTO1 input or the HWTO2 input is turned ON, the power removal status cannot
be released.
• If the ON-time of the HWTO1 input and the HWTO2 input are less than 15 ms, the power removal
status may not be released.
• When the power removal status is released, a shut-off state of supplying the power to the motor
by the hardware is also released.
• The ETO-CLR input is not safety-related part of a control system.
