APPENDIX 5
Fault (major, minor) which could occur during normal operation is also detected during PG zero-pulse
adjustment. If a fault occurs including minor fault, the motor stops after coasting (baseblock) and PG
zero-pulse adjustment is interrupted regardless of the fault stop mode.
During PG zero-pulse adjustment, errors indicated in the table below are also detected in addition to
the faults which could occur in normal operation. The motor stops after coasting (baseblock) and PG
zero-pulse adjustment is interrupted if any of these errors is detected. The error messages are not re-
corded in the fault history.
When the PG zero-pulse adjustment is interrupted, the value set for T1-02 is automatically returned
to "0." The setting for all constants (including T1-0j) is automatically returned to the setting made
before the start of PG zero-pulse adjustment and the setting of these constants cannot be changed.
Follow the corrective actions shown in Fig. A-1.
