Each time one of OC, OV, OH, or GF fault occurs, one is added to
the number of auto reset/restart operation, and auto reset/restart
operation is performed according to the following procedure. How-
ever, auto reset/restart operation is not performed in the following
cases:
Note GF is for single-phase input models only.

1. No fault occurs for 10 minutes or more.
2. A fault reset signal is input from external terminals or digital op-
erator.
2-10-23Setting Prohibit Frequency Range (No. 50 to No. 53)
Set the range of setting prohibit frequency in the units of 0.1 Hz.
The range of the setting prohibit frequency is determined as fol-
lows, depending on combinations with No. 50 to No. 52.
No.50to No.52 --No.53 ≤ the rangeofthesettingprohibitfrequen-
cy ≤ No. 50 to No. 52 + No. 53

Note 1. Constant-speed operation is prohibited in the setting prohibit
frequency range. Output frequency does not jump during ac-
celeration or deceleration, which is performed smoothly.,
2. Set as follows; No. 50 ≥ No. 51 ≥ No. 52
