FANUC Alarm ISD-058 — WARN Low air supply pressure (IPS…)

Manufacturer wording — WARN Low air supply pressure (IPS%d)
The manual prints placeholders; your controller fills them in with the real group, axis or number.

FANUC ISD-058 (“WARN Low air supply pressure (IPS…)”): The pressure switch monitoring the air supply to pneumatic servo valves is switched off because the air supply is too low. First check: If the gauge indicates adequate pressure, verify that the Air Supply Pressure digital input is not simulated.
