It is used to set the AC drive running mode when the set frequency is lower than the frequency lower limit. The ED2000 provides
three running modes to satisfy requirements of various applications.
P8.15
Droop control
Default
0.00Hz
Setting Range
0.00Hz ~ 10.00Hzs
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.
P8.16
Accumulative power-on time threshold
Default
0h
Setting Range
0h ~ 65000h
If the accumulative power-on time (P7.13) reaches the value set in P8.16 parameter, the corresponding M01 terminal outputs ON
(P6.01=24).
P8.17
Accumulative running time threshold
Default
0h
Setting Range
0h ~ 65000h
It is used to set 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).
P8.18
Startup protection
Default
0
Setting Range
No
Yes
This parameter is used to set whether to enable the safety protection. If it is set to 1, the AC drive does not respond to the running
command valid upon AC drive power-on (for example, an input terminal is ON before power-on). The AC drive responds only after
the running command is cancelled and becomes valid again. In addition, the AC drive does not respond to the running command
valid upon fault reset of the AC drive. The run protection can be disabled only after the running command is cancelled.
In this way, this parameter is set to 1, the motor can be protected from responding to run commands upon power-on or fault
reset in unexpected conditions.
P8.19
Frequency detection value (FDT1)
Default
50.00Hz
Setting Range
0.00Hz-maximum frequency
P8.20
Frequency detection hysteresis (FDT1)
Default
5.0%
Setting Range
0.0%-100.0% (FDT1 level)
If the running frequency is higher than the value of frequency detection the corresponding M01 terminal becomes ON. If the
running frequency is lower than value of P8.19, that the M01 terminal outputs on is cancelled.
These two parameters are respectively used to set the detection value of output frequency and hysteresis value upon cancellation
of the output. The value of P8.20 is a percentage of the hysteresis frequency to the frequency detection value (P8.19).The FDT
function is shown in the following figure.
