4.6.2 External Force Limit
Use this function to limit force by inputting a signal from the host controller at specific times during machine
operation. For example, some pressure must continually be applied (but not enough to damage the workpiece)
when the robot is holding a workpiece or when a device is stopping on contact.
(1) Input Signals
Use the following input signals to limit a force by external force limit.
Note: Use parameter Pn50B.2 and Pn50B.3 to allocate the /P-CL signal and the /N-CL signal for use. For details, refer to
3.3.1 Input Signal Allocations.
(2) Related Parameters
Set the following parameters for external force limit.
The setting unit is a percentage of the rated force.
Note: If the settings of Pn483, Pn484, Pn404, and Pn405 are too low, the force may be insufficient for acceleration or
deceleration of the servomotor.
