VD120 Series Inverter User Manual Parameter Description
-
125
-
Frequency converter starting at each time, timing starts from 0, timing remaining run time can be
viewed by U0-35.
Timing run time set by Fb-37, Fb-38, unit of time for minutes.
Fb-39
Module Temperature
Reached
0°C~100°C
75°C
○
Inverter radiator temperature reached the temperature, the inverter multi-function DO output "module
temperature reached" ON signal.
Fb-40
Lower Limit of AI1 Input
Voltage Protection Value
0.00V~Fb-41
3.10V
○
Fb-41
Upper Limit of AI1 Input
Voltage Protection Value
Fb-40~10.00V
6.80V
○
When the analog input AI1 value is less than Fb - 40, or the AI1 input is greater than Fb-41, the
inverter muti-function the DO output "AI1 input limit exceed" ON signal, for indicating whether the
input voltage of AI1 in the setting range.
Fb-42
Wakeup Frequency
Dormancy frequency (Fb-44)~max
frequency (F0-10)
0.00Hz
○
Fb-43
Wakeup Delay Time
0.0s~6500.0s
0.0s
○
Fb-44
Dormancy Frequency
0.00Hz~wakeup frequency (Fb-42)
0.00Hz
○
Fb-45
Dormancy Delay Time
0.0s~6500.0s
0.0s
○
This set of parameters are used to realize the dormancy and wakeup function in water supply
applications.
In the running process of frequency converter, when setting frequency less than or equal to Fb-44
dormancy frequency, after Fb-45 delay time, frequency converter to enter a dormant state, and
automatically stop.
If the frequency converter in a dormant state, and the current running command is valid, then when
setting frequency greater than or equal to Fb-42 wakeup frequency, and the frequency converter
starts up after Fb-43 delay time.
In general, please set the wakeup frequency greater than or equal to dormancy frequency. Set the
wakeup frequency and dormancy frequency is 0.00Hz, then dormancy and wakeup function is invalid.
In dormancy function is enabled, if frequency source use PID, the dormant state PID whether the
arithmetic, influenced by function code FA-29, must be selected PID stop operation (FA-29=1) at this
time.
Fb-48
Timing Braking
Frequency
0.00Hz~50.00Hz
1.50Hz
○
Fb-49
Timing Braking Time
0.0s~60.0s
2.0s
○
In the process of stop, when the output frequency is less than the value of Fb-48, DO function 41
(timing brake) closed after output the set time of Fb-49. As shown in the figure below.
