prohibited, set this parameter to 1.
b2-16
Forward/Reverse rotation dead-zone time
Default
0.0s
Setting Range
0.0~3000.0s
It is used to set the time when the output is 0 Hz at transition of the frequency inverter forward rotation and reverse
rotation, as shown in the following figure.
Diagram 5-9 Forward/Reverse rotation dead-zone time
b2-17
Running mode when set frequency less than limited lower
frequency
Default
0
Setting
Range
0
Run at frequency lower limit
1
Stop
2
Run at zero speed
It is used to set the frequency inverter running mode when the set frequency is lower than the frequency lower limit.
The EM15 provides three running modes to satisfy requirements of various applications.
b2-18
Droop control
Default
0.00Hz
Setting Range
0.00Hz~10.00 Hz
This function is used for balancing the workload allocation when multiple motors are used to drive the same load. The
output frequency of the frequency inverters decreases as the load increases. You can reduce the workload of the
motor under load by decreasing the output frequency for this motor, implementing workload balancing among
multiple motors.
b2-19
Terminal JOG priority
Default
0
Setting
Range
0
Disabled
1
Enabled
It is used to set whether terminal JOG is priority. (Only external terminal control mode is valid)
If terminal JOG is priority, the frequency inverter switches to terminal JOG running state when there is a terminal
JOG command during the running process of the frequency inverter.
b2-21
Setting running time reach threshold
Default
0h
Setting Range
0~65000 h
It is used to set the accumulative running time threshold of the Frequency inverter. If the accumulative running time
(b9-09) reaches the value set in this parameter, the corresponding DO terminal becomes ON.
b2-22
Action after running time reached
Default
0
Setting
Range
0
Continue to run
1
Stop
This function is used to define the action after b2-21 preset time reached. Setting 0 inverter will continue work after
present running time reached; and set 1, the inverter will stop.
