Description

An excessive load was put on the sensor head.

Remedy · Remède

1. Make sure that the value of 'Insert Force' in 'Basic Data' is not too large. If not, go to the next step. 2. Bad impedance parameters can cause vibration during force control. Increase the Mass value in the impedance parameters.
