FANUC Alarm ARC-057 — Cannot ramp t1=… > t2=…
Manufacturer wording — Cannot ramp t1=%d > t2=%d
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC ARC-057 (“Cannot ramp t1=… > t2=…”): The Arc process ramping cannot execute because the delay (t1) to communicate with the welder is larger than the ramping loop time (t2). First check: Increase $aweramp[eq].$time_factor by 1.
