CP1

Comparator 1 Limit Error

Yaskawa · V1000 AC Drive

What does CP1 mean?

This fault activates when the monitored value, selected in H2-20 [Comparator 1 Monitor Selection], falls within the predefined range set by H2-21 [Comparator 1 Lower Limit] and H2-22 [Comparator 1 Upper Limit]. It signals that a critical process variable has entered a restricted operating window, indicating an abnormal condition that requires immediate investigation to prevent operational issues.

Complete Troubleshooting Guide

  1. 1

    Examine the current value of the monitored parameter (H2-20) and review the configured comparator limits (H2-21, H2-22) to understand the deviation.

  2. 2

    Investigate the physical process or equipment being monitored to pinpoint and rectify the underlying cause of the value entering the restricted range.

  3. 3

    If necessary and appropriate, adjust the comparator limits to accurately reflect the safe and desired operating conditions for the specific application.

  4. 4

    Perform a Fault Reset only after the cause of the monitoring value deviation has been thoroughly resolved and corrected.
