Reverse control
PB.13
Setting Range
It is used to set whether the AC drive allows reverse rotation. In the
applications where reverse rotation is prohibited, set this para.meter
to 1 .

PB.14
Setting Range 1
It is used to set the AC drive running mode when the set frequency
is lower than the fr e quency lower limit. The NZ2000 provides three
running modes to satisfy requirements of various applications.

Settin Ran e O.OOHz-10.00Hz
This function is used for balancing the workload allocation when
multiple motors are used to drive the same load. The output
frequency of the AC drives 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
between multiple motors.
Accumulative power-on time
PB.16 threshold
Selling Range !Oh-65000h
If the accumulative power-on time (P7 . 1 3} reaches the value
set in PB. 16 parameter, the corresponding M01 terminal outputs
ON(P6.01=24).
Accumulative running time
threshold
PB.17
It is used to sat the accumulative running time threshold of the AC
drive. If the accumulative running time {P7.09) reaches the value
set in this parameter, the corresponding M01 terminal outputs
ON(P6.01 =40).
