Setting 3: Coast to Stop with Timer
When the Run command is removed, the drive will turn off its output and the motor will coast to stop. The drive will not start
if a Run command is input before the time t (C1-02) has expired. Cycle the Run command that was activated during time t
after t has expired to start the drive.

n
b1-04: Reverse Operation Selection
Enables and disables Reverse operation. For some applications, reverse motor rotation is not appropriate and may cause
problems (e.g., air handling units, pumps, etc.).
No. Parameter Name Setting Range Default
b1-04 Reverse Operation Selection 0, 1 0
Setting 0: Reverse operation enabled
Possible to operate the motor in both forward and reverse directions.
Setting 1: Reverse operation disabled
Drive disregards a Reverse run command or a negative frequency reference.

b8-27: q-Axis Current Compensation Method when Output Voltage Is Limited
Sets a compensation method for the q-axis current when output voltage is limited.
There is normally no need to change this parameter from the default value.
