FANUC Alarm SRVO-036 — SERVO Inpos time over

Manufacturer wording — SERVO Inpos time over (G:%d A:%d)
The manual prints placeholders; your controller fills them in with the real group, axis or number.

FANUC SRVO-036 (“SERVO Inpos time over”): The in-position monitor time ($PARAM_GROUP.$INPOS_TIME) has elapsed, but the inposition state ($PARAM_GROUP.$STOPTOL) h=as not yet been set. First check: 1. Check whether the applied load exceeds the rating. Likely part: Servo amplifier (Servo amplifier).

Description

The in-position monitor time ($PARAM_GROUP.$INPOS_TIME) has elapsed, but the inposition state ($PARAM_GROUP.$STOPTOL) h=as not yet been set.

Remedy

1. Check whether the applied load exceeds the rating. If so, reduce the applied load. If an excessive load is applied, the torque required for acceleration, deceleration, and so forth exceeds the maximum available torque of the motor. Therefore, it might prove impossible to correctly respond to an issued command, resulting in the output of this alarm. 2. Check each interphase voltage of the three-phase voltage (200 VAC) applied to the servo amplifier. If the voltage is found to be 170 VAC or below, check the input power supply voltage. A sub-standard voltage, applied to a servo amplifier, results in a lower-than-normal torque. Therefore, it might prove impossible to correctly respond to an issued command, thus resulting in the output of this alarm. Check phase-to-phase voltage across the three pins of connector CRM38A of the servo amplifier. 3. If the input power supply voltage is found to be 170 VAC or higher, replace the servo amplifier. 4. Check the motor power cables (RM1, RM2, RM3) for damage, to cable or pins, and that the connector is securely connected. WARNING: By completing the next step you will be altering the positional reference for the robot since you are replacing hardware. You must slowly verify all positional data and touch-up any paths or points that have changed. Otherwise, you could injure personnel or damage equipment. 5. Replace the motor, and remaster the robot.
