Transition to power removal status
If both the HWTO1 and HWTO2 inputs are turned OFF, the driver transitions to the power removal status, and the
power supplying to the motor is shut off by the hardware, causing the motor to put into a non-excitation state.
In the power removal status, the status of the motor and driver will be as follows. [When the “HWTO mode selection”
parameter is set to “0: Alarm is not present (initial value)”]
• The ETO-MON output is ON.
• The READY output, the PLS-RDY output, and the MBC output are OFF.
• The PWR/ALM LED blinks in green.
• When an electromagnetic brake motor is used, the electromagnetic brake is in a state of holding the motor output
shaft.
• Be sure to check the motor is in a standstill state before executing the power removal function. If
the power removal function is executed while the motor is operated, it may cause damage to the
motor, driver, or equipment.
• It takes 15 ms maximum from when the HWTO1 input and the HWTO2 input are turned OFF until
when the driver is in the power removal status.
• To transition to the power removal status, be sure to turn the HWTO1 input and the HWTO2 input
OFF for at least 15 ms.
• The ETO-MON output, the READY output, the PLS-RDY output, the MBC output, the PWR/ALM LED,
and the electromagnetic brake are not safety-related parts of a control system.
