Combination type-hollow shaft at gearhead
The rotation directions of the gearhead output shaft relative to the motor output shaft are as shown in the gures
below.

Sliding noise of electromagnetic brake
Sliding noise of the brake disk for the electromagnetic brake motor may be generated during operation.
It is no functional problem.

Power removal function
z
If the power removal function is activated, the motor holding force is lost and the motor output shaft
may be rotated by external forces (gravity on a vertical axis, etc.). If the motor output shaft is required
to hold in position, install an external brake mechanism or equivalent. Failure to do so may result in
injury or damage to equipment.
z
The power removal function is a function to shut o the power supply to the motor by stopping
operation of the inverter circuit. It is not a function to physically shut o the driver and the motor.
When touching the driver or the motor, turn o the driver power and check the PWR/SYS LED is turned
o. Failure to do so may result in electric shock.
z
Be sure to check the motor is in a standstill state before transitioning to the power removal status.
Transitioning to the power removal status while the motor is rotating may cause damage to the motor,
driver, or equipment.

Saving the data
z
Notes when saving the data to the non-volatile memory
Do not turn o the power supply while writing the data to the non-volatile memory, and also do not turn o for ve
seconds after the completion of writing the data. Doing so may abort writing the data and cause an alarm of EEPROM
error to generate.
The non-volatile memory can be rewritten approximately 100,000 times.
