9.4.5 Setting the detection width for the VA output
"VA detection width" parameter
The VA output is output when the motor reaches the plus or minus range of the "VA detection width" with respect to
the set rotation speed.
The VA detection width can be set in a range of 1 to 400 r/min with respect to the set rotation speed.
(Factory setting: 200 r/min)
Example: When the motor speed changes from the setting speed 1 to the setting speed 2

9.4.6 Holding a load at motor standstill(Load holding function)
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.
“Load holding function selection” parameter
When 1 (enabled) is set, a force to hold the shaft electrically can be 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.
“Load holding torque limiting setting value” parameter
The load holding torque limiting value is set with this parameter.
If -1 is set, the torque limiting value set to the selected operation data number is applied.
When the setting value of the torque limiting value exceeds 50% of the rated torque, the load holding torque is limited
to a maximum of 50%.
If a value of 0 to 50% is set, the torque limiting value having set is applied.
Note
•
Do not use a motor in a vertical application.If the power supply to the driver is turned o or if an alarm is generated,
the holding force is lost. This function cannot be used for keeping the load position when the motor stops.
•
If the load holding function is enabled, the time until the motor stops will be longer than when set to disable
according to the setting or load conditions. In addition, the motor output shaft may vibrate when the motor stops.
