·
After changing these parameters, turn OFF the main circuit and control power
supplies, and then turn them ON again to enable the new settings.
·
Stop by dynamic brake: Stops by using the dynamic brake (short circuiting its
electrical circuit).
·
Coast to a stop: Stops naturally, with no brake, by using the friction resistance
of the servomotor in operation.
· Plug braking: Stops by using plug braking limit torque.
·
Zero Clamp Mode: A mode forms a position loop by using the position
reference zero.
·
Dynamic brake is an emergency stop function, and one of the general methods to cause a servomotor sudden stop.
·
Dynamic brake suddenly stops a servomotor by shorting its electrical circuit.
· If the servomotor is frequently started and stopped by turning the power ON/OFF or using the servo ON signal(/S-ON),
the DB circuit will also be repeatedly operated, degrading the servo drive’s internal elements.
·
Use the speed input reference and position reference to control the starting and the stopping of the servomotor.

·
This sets the stop torque for when the overtravel signal (P-OT,N-OT) is input.
·
The setting unit is a percentage of the rated torque. (the rated torque is 100%)
·
The value large enough to be the servomotor maximum torque, 300% is set as the factory setting for plug braking limit
torque. However, the actual output plug braking limit torque is determined by servomotor ratings.
