Before inverter starts, the motor may be running at low speed or in opposite rotation
status. If inverter starts immediately at mean time, overcurrent may occur. In order to
avoid such fault, before inverter starts, please start DC brake to stop motor, and then the
inverter runs to setting frequency as per setting direction. See F3-22
,
F3-23 for the setting
method of starting DC brake.

Stop Mode Setting:
Ramp to Stop
F0-20=0
Motor is ramp-to-stop in setting deceleration time.

Coast to Stop
F0-20=1
While the stop command is input, inverter stops output immediately, and the
motor coasts to stop. The stop time is up to load inertia.
If there is a coast-to-stop terminal, when it is on, the inverter enters coast-to-stop status
immediately, and when it is off, the inverter will not restart only if regiving the run
command.

F0-21=0
JOG/+- button on keypad is for jog function.
F0-21=1
JOG/+- button on keypad is for positive/negative input switching function,
i.e. when the settings are positive speed, positive PID, and positive torque
JOG/+- button is for switching to negative speed, negative PID, and
negative torque.

F0-22
For setting speed display. If F0-22=0, then the reference input value displayed
on keypad is the target output frequency of inverter. If F0-22=1, then the
reference input value is the target output speed of inverter.
F0-23
Customer defined scaling. Mechanical speed = Mechanical speed coefficient
(Customer defined scaling) * Output frequency. When the unit of setting speed
is rpm, adjsut the parameter to make the displayed value of motor speed match
the actual value.
