FANUC Alarm FRCE-512 — AIT P direction environment NG (F:…)

Manufacturer wording — AIT P direction environment NG (F:%d^1)
The manual prints placeholders; your controller fills them in with the real group, axis or number.

FANUC FRCE-512 (“AIT P direction environment NG (F:…)”): An environmental characteristic in the P direction could not be acquired in the impedance parameters auto tuning. First check: Modify the force control parameters in the following order; then execute the impedance parameters auto tuning again.

Description

An environmental characteristic in the P direction could not be acquired in the impedance parameters auto tuning.

Remedy

Modify the force control parameters in the following order; then execute the impedance parameters auto tuning again. 1. The impedance change for the environmental characteristic acquisition might be too rough. Increase the system variable $CCSCH_GRPxx[i].$TD.$NUM_KEI[1]. [The schedule number is calculated as ((xx-10)*5+i). Modify the appropriate $CCSCH_GRPxx[i]. 2. The desired force might be too small. Increase the desired force. 3. The desired force might be too large. Decrease the desired force.
