Motor’s power supply is supplied to the AMP according to the open/close status of Magnetic contactor MC1, and MC2.

Status of MC1 and MC2 are being monitored by Main’s conditions and E0127 (MSHP operation error) or E0140 (MSPR operation error) will be generated when an abnormal operation is detected.

 

(1)   E0140 (MSPR operation error)

For a reason that cannot be identified by Main, the Magnetic contactor MC1

①    Does not turn On while an attempt is made,

②    Turns off while it should stays on

 

(2)   E0127 (MSHP operation error)

For a reason that cannot be identified by Main, the Magnetic contactor MC2

①    Does not turn On while an attempt is made,

②    Turns off while it should stays on

 

In order for MC1 or MC2 to on, many conditions need to be satisfied, and even if when they are on, they can be off for some reasons. Main can identify the causes for Magnetic contactor’s operation error if it is a case that provides a monitoring function such as safety signals. However if the main cannot identify the Magnetic contactor’s operation error, a number of examines are required.
