YASKAWA SIEPC71061737D GA800 Drive Technical Reference 361
Code Name Causes Possible Solutions
CP2 Comparator 2 Limit Fault
The monitor value set in H2-26 [Comparator 2
Monitor Selection] was outside the range of H2-27
[Comparator 2 Lower Limit] and H2-28
[Comparator 2 Upper Limit].
Examine the monitor value and remove the cause of the fault.
Note:
• The drive detects this error when the terminal is set to H2-01 to H2-03 = 67 [MFDO Function Selection = Comparator2].
• Do a Fault Reset to clear the fault.
• Set the stopping method for this fault in H2-35 [Comparator2 Protection Selection].
