6-3 Special Functions
Note 1
：
FR(Forward), RR(Reverse) and FR/RR(Revolution direction) are different signals each other.
Note 2
：
If FR/RR state is changed at inverter driving, then revolution direction of motor can change. Revolution
direction decide by F1001(Motor control mode selection) setting value.
• F1001 = 1 (V/f control mode) and F1309 = 0
The inverter operates according to the function code settings when starting and stopping. Consequently,
the change in output frequency around 0 Hz may not follow a straight line, depending on settings such as
the starting frequency. Since DC braking does not work when reversing the direction of rotation, set the
DC braking start frequency low.
• F1001 = 1 (V/f control mode) and F1309 = 1
A process of continuous deceleration to acceleration in the opposite direction, which has nothing to do
with the relevant function codes for starting and stopping.
• F1001 = 2 (Speed sensorless control mode), 3 (speed sensor control mode)
Braking excitation or starting excitation is not applied when switching the direction of rotation. This
allows ―forward and reverse run‖ in a continuous operation.
Note 3: During torque control, the direction of motor rotation depends on the load side, therefore, FR/RR terminal
disable. Please only use RUN and STOP during torque control.
