9.9.4 Limiting Linear Servomotor Speed during Force Control

During force control, the linear servomotor is controlled to output the specified force, which means that the linear
servomotor speed is not controlled. Accordingly, when an excessive reference force is set for the mechanical load
force, it will prevail over the mechanical load force and the linear servomotor speed will greatly increase.
This function serves to limit the linear servomotor speed during force control to protect the machine.

Danger of damage due to
excessive machine speed.
0 Uses the value set in Pn480 as the speed limit (internal speed limit function).
1 Uses V-REF (CN1-5, 6) as an external speed limit input. Applies a speed limit using the input
voltage of V-REF and the setting in Pn300 (external speed limit function).
Description
