and AM.
Set the full-scale value to output the output
current monitor value to terminal FM and AM.

* The increments and setting range differ
0 to 3600A

according to the inverter capacity. (55K or
lower/75k or higher)
Set the full-scale value to output the torque
0 to 400%
monitor value to terminal FM and AM.
The coasting time is as follows:
1.5K or lower................................. 0.5s,
2.2K to 7.5K .................................. 1.0s,
0
11K to 55K .................................... 3.0s,

Set a voltage starting time at restart.
Consider according to the magnitude of
load (inertia moment/torque).
0 to 100%
Consider the rated inverter current as
0 to 220% 100% and set the stall prevention
operation level during restart operation.
0 Without rotation direction detection
1 With rotation direction detection
When Pr. 78 = "0", the rotation direction is
detected.

When Pr. 78 = "1", "2", the rotation direction
is not detected.
