FANUC Alarm PNT2-175 — Non-increasing cal table

Manufacturer wording — (%s) Non-increasing cal table
The manual prints placeholders; your controller fills them in with the real group, axis or number.

FANUC PNT2-175 (“Non-increasing cal table”): After the calibration table has been shifted or a new calibration table created, a non-increasing table of flow command values is detected. First check: Verify regulator is working properly.

Description

After the calibration table has been shifted or a new calibration table created, a non-increasing table of flow command values is detected. Unstable flow rates were encountered. The canister position change is not proportional to fluid regulator command. The canister position feedback is unstable.

Remedy

Verify regulator is working properly. Verify fluid restrictor is suitable for the desired flow rates. Check proper feedback from the linear potentiometer. If this occurs as a result of a table shift, calibrate the color valve in which the cal table has become non-increasing.
