12.1-06-18
Status 3-2: Pr.06-48 ≠ 0, Pr.07-02 = 0 (OPHL detected before operation)
In this period, if an OPHL occurs within the time for Pr.06-48, the drive executes the Pr.06-
45 setting after the drive starts counting for half the time of Pr.06-48.

Input phase loss detection action (OrP)
Default: 0
Settings 0: Fault and ramp to stop
1: Fault and coast to stop
 The drive executes the input phase loss protection according to Pr.06-53.

Derating Protection
Default: 0
Settings 0: Constant rated current and limit carrier wave by load current and
temperature
1: Constant carrier frequency and limit load current by setting carrier wave
2: Constant rated current (same as setting 0), but close current limit
 Allowable maximum output frequency and the minimum carrier wave limit in control mode:
For VF and SVC modes:
When the maximum output frequency is 599 Hz, the minimum carrier wave is 6 k.
 Setting 0:
 Actual over-current stall prevention level = derating ratio × over-current stall prevention level
(Pr.06-03 and Pr.06-04).
 Rated current derating level: derating ratio × rated current (Pr.00-01).
