Manufacturer wording — %sTPR exceeds Can Volume

FANUC PNT1-423 (“TPR exceeds Can Volume”): The calculated TPR exceeds the can volume. First check: Set up for a re-dock.

Updated 2026-09-17 · LogrobotLM reference

Description

The calculated TPR exceeds the can volume. The TPR for that job is too large. When using Accustat, if the TPR for a job normally approaches the limit of the size of the canister, then the adaptive fill tolerance might attempt to add additional paint beyond the limit of the canister volume.

Remedy

Set up for a re-dock. Decrease the Adaptive Fill Gain parameter in the AccuStat setup screen. Reduce the size of the job if it is larger than 1550 ccs which is the maximum volume of the AccuStat canister.
