8.9 Holding a load at motor standstill
If the "slight position-keeping selection" parameter is set to ON (enable), the holding torque is somewhat generated
when the motor stops (slight position-keeping torque).
The factory setting is OFF (disable). Refer to p.24 or p.26 for how to change the parameter.
•
Up to 50% of the rated torque is generated according to the angle variation of the motor output shaft (figure).
The position of a load exceeding 50% of the rated torque cannot be kept.
•
When the power supply to the driver is turned off, the holding torque is lost. This function cannot be used for keeping
the load position in the event of a power outage.
