Holding a load at motor standstill
Although the electromagnetic brake motor can hold a load by the electromagnetic brake when the motor stops, even if a motor
without an electromagnetic brake is used, a certain degree of holding force can be generated at motor standstill by the load
holding function.
z
"Load holding function selection" parameter (ID: 2069)
If the "Load holding function selection" parameter is set to “1: Enable,” a certain degree of holding force is generated when the
motor stops (load holding torque).
The factory setting is “0: Disable.”
If the angle of the motor output shaft is changed about 15°, a holding force is generated.
If the motor holds a large load, heat generated by the driver increases. Therefore, use in a state where a load does not exceed 50%
of the rated torque.
•
For the load holding torque, the holding force is lost when the power supply to the driver is turned o.
This function cannot be used for keeping the load position in the event of a power outage.
•
If the torque limiting value set in the selected operation data number is lower than 50%, the load holding torque will be
generated up to the torque limiting value.
•
If the load holding function is set to enable with the driver for electromagnetic brake motor, the electromagnetic brake is
released, and the load holding torque generates to hold a load when the motor stops.
When the main power supply is turned o, the electromagnetic brake holds a load.
If the load holding function is set to enable, the time until the motor stops will be longer than the disabled setting according to
the setting or load conditions.
In addition, the motor output shaft may vibrate when the motor stops.

Setting the acceleration/deceleration time
z
"Acceleration/deceleration unit selection" parameter (ID: 329)
When the setting is "0"
The acceleration time is set as the time needed for the motor to reach the
rated rotation speed (3000 r/min) from the standstill state.
The deceleration time is set as the time needed for the motor to stop from
the rated rotation speed (3000 r/min).

When the setting is "1"
When the digital setting is used to set the rotation speed, you can set by the
time in the right gure with reference to the set rotation speed.
However, if the "Operation input mode selection" parameter is set to “3” or “5,”
the setting “1” of the "Acceleration/deceleration unit selection" parameter is
not applied, and the motor operates according to the data in the setting “0.”
Refer to p.64 for the "Operation input mode selection" parameter.

Softening an impact at starting and stopping
z
"Impact softening lter" parameter (ID: 330)
This is a function to accelerate slowly and decelerate slowly so
that the position of a transported load does not move when the
motor starts and stops.
It can soften an impact when the motor starts, stops, and changes
the speed against the set acceleration time and deceleration
time.
