0 to 5 A fault for retry can be selected.
0 No retry function
Set the number of retries at fault
1 to 10 occurrence. A fault output is not provided
during retry operation.
Set the number of retries at fault
occurrence. (The setting value - 100 is the
101 to 110
number of retries.) A fault output is
provided during retry operation.
Set the waiting time from when an inverter
0 to 10s
fault occurs until a retry is made.

0
retry.

PWM carrier frequency can be changed.
The setting displayed is in [kHz].
0 to 15/ Note that 0 indicates 0.7kHz, 15
indicates 14.5kHz and 25 indicates
0 to 6, 25

capacity (55K or less/75k or more)
0 Soft-PWM invalid
When Pr. 72="0 to 5" ("0 to 4" for the 75K or
1
more), Soft-PWM is valid.
PWM carrier frequency is constant
independently of load.
When the carrier frequency is set to 3kHz
0
or more (Pr. 72 ≥ 3), perform continuous
operation at less than 85% of the rated
inverter current.
Decreases PWM carrier frequency

automatically when load increases.
