speed
By setting any value other than "9999", set speeds 8 to 15.
This function is designed to change the running speed in stages by changing the ON/
OFF combination of the contact signals (RH, RM, RL, REX signals).

You can select to exercise Soft-PWM control and long wiring mode. When Soft-PWM
control is made valid, you can change the metallic tone of motor sound into an
unoffending complex tone. Surge voltage is surpressed in the long wiring mode
regardless of the wiring length between the inverter and motor. (When operating a
400V motor with wiring length of 40m or more, select long wiring mode.)
0: Soft-PWM control invalid, long wiring mode invalid
1: Soft-PWM control valid (when Pr. 72 = "1 or 2"), long wiring mode invalid
10: Soft-PWM control invalid, long wiring mode valid (carrier frequency is 2.25Hz *)
11: Soft-PWM control valid, long wiring mode valid (carrier frequency is 2.25Hz *)
*The Pr.72 "PWM frequency selection" setting is made invalid.
You can control the operation of the cooling fan built in the inverter.
0: The fan is always operated at power-on of the inverter.
1: The fan is always on while the inverter is running. During a stop, the inverter status is
monitored and the fan switches on-off according to the temperature.
Set to allow the motor to be coasted to a stop by turning off the start command during
V/F or speed control.
0 to 100s: Coasting to stop
9999: Deceleration to stop
You can disable the output phase failure protection function that stops the inverter
output if one of the inverter output side (load side) three phases (U, V, W) opens.
0: Without output phase failure protection
1: With output phase failure protection
When you selected the override in Pr. 73, you can adjust the override bias (0 to 200%)
and override gain (0 to 200%).
You can select the stopping method at a power failure.
0: Coasting to stop, inverter output shutoff
1: Inverter is decelerated to a stop.
