C25.20 Function Description Range Unit
Default
Setting
Cascade Low Frequency 0.000~400.000 Hz 20.000
Function: In cascade control systems, due to less consumption, the inverter
output f requency is low, when output f requency is below the
“cascade low f requency” and it lasts more than “low f requency
delay time”, the corresponding multi-f unction terminals (relay) acts,
auxiliary pump is stopped.
C25.21 Function Description Range Unit Default Setting
Low Frequency Delay
Time
0.0~3600.0 s 20.0
Function: This parameter used together with “Cascade Low Frequency”.
C25.2* Cascade Frequency
C25.12 Function Description Range Unit Default Setting
Multi Pressure Time 0.00~23.59 h 0.00
Function: This is an array parameter, and it can set up to 6 time-integral.
T0 Set range: 0.00 – 23.59 Default setting: 0.00
T1- T5 Set range: 0.00 – 23.59 Default setting: 23.59
Up to 6 set points corresponding to the 6 time-integral can be set as follows:
Attention: 1
、
This rule must be followed: T0≤ T1 ≤ T2≤ T3 ≤ T4 ≤ T5.
2
、
If Tx = T(x+1) (x = 1, 2, 3, 4, 5), T(x+1) is invalid.
3
、
If multi-pressure selection(C25.10) is disabled, use the pressure
setting set in C03.10[1] , where the current using pressure can be
displayed.
