0:Run at the low limit speed/frequency
Keeps running at the low limit speed/frequency when the set frequency is lower than the low
limit..
1: Stop by stop mode
Stop mode set in d2-06.
2: Sleep
SVC mode, when the inverter setting speed is lower than 12r/min, the motor stops and enter DC
excitation operation. Under V/F control, it blocks the PWM wave.

0: OFF
No prohibit for the rotation direction.
1:
Prohibit running at opposite direction of the starting command
The direction opposite to the operation command at the start of the motor is prohibited. Once
the inverter is started, even if the forward/reverse run command is switched, the direction of the
prohibition will not change if the inverter is not stopped. During forward rotation ,when reverse
run command provided, the motor will decelerate to forward E0-01 and maintains the speed.
2: Prohibit reverse direction running
Regardless of the direction of the running command, the motor is prohibited from running in the
opposite direction (the rotation direction with output voltage sequence U→V→W is forward
direction). Under reverse command, the running speed/frequency is limited to forward E0-01
and maintains the speed.
Note: Under vector control, if d2-00 is set to other than 0 (speed control), the parameter must be
set to 0. It means that anti-reverse function is not supported during torque control.

0
When the DC bus voltage is greater than
P0-00
+ 10.0V, the activated function prevents the
inverter from being tripped by overvoltage. As shown in
Fig.7-5
:
0:OFF
The function only valid within 10 seconds when start.
1:ON
2:OFF_1
Invalid all the time. Used to solve the problem that the hoisting equipment enters the
overvoltage stall state when it starts.
