5 Operation
5.2.3 Overtravel
(4) Emergency Stop Force for Overtravel
Pn406
• The setting unit is a percentage of the rated force (i.e., the rated force is 100%)
• The factory setting is 800% so that the setting is large enough a value to operate the servomotor at maximum
force. The maximum value of emergency stop force that is actually available, however, is limited to the
maximum force of the servomotor.
(5) Terms
Dynamic Brake (DB)
Dynamic braking (DB) is a standard method for stopping the servomotor in
emergencies. By short-circuiting the electric circuits, the servomotor comes to
a quick stop. The dynamic braking circuit is built into the SERVOPACK.
Coast to a stop
Stops naturally, with no brake, by using the friction resistance of the motor in
operation.
Decelerate to stop
Stops by using deceleration (braking) force.
Zero Clamp Mode
A mode forms a position loop by using the position reference zero.
