5. Description of Function Codes
59
b4-39
IGBT module temperature threshold
Default
75°C
Setting Range
25~100°C
When the heatsink temperature of the frequency inverter reaches the value of this parameter, the corresponding DO
becomes ON, indicating that the IGBT module temperature reaches the threshold.
5.6 Group b5: Pulse/Analog input terminals
b5-00
Pulse minimum input(HDI)
Default
0.00 kHz
Setting Range
0.00 kHz ~b5-02
b5-01
Corresponding setting of pulse minimum input
Default
0.00%
Setting Range
-100.00% ~100.0%
b5-02
Pulse maximum input
Default
50.00 kHz
Setting Range
b5-00 ~ 50.00 kHz
b5-03
Corresponding setting of pulse maximum input
Default
100.0%
Setting Range
-100.00% ~100.0%
b5-04
Pulse filter time
Default
0.10s
Setting Range
0.00s~10.00s
Can only be input by HDI. The method of setting this function is similar to that of setting AI1 function..
Diagram 5-20 The relationship between pulse input and setting value
b5-05
AI1 input voltage lower limit of protection
Default
3.10 V
Setting Range
0.00 V~ b5-06
b5-06
AI1 input voltage upper limit of protection
Default
6.80 V
Setting Range
b5-05~10.00 V
These two parameters are used to set the limits of the input voltage to provide protection on the frequency inverter.
When the AI1 input is larger than the value of b5-06 or smaller than the value of b5-05, the corresponding DO
becomes ON, indicating that AI1 input exceeds the limit. Every analog input has five setting points to facilitate the
setting of the AI curve.
b5-07
AI1input minimum value
Default
0.02 V
Setting Range
0.00 V ~ b5-15
b5-08
Corresponding setting of AI1 minimum input
Default
0.0%
Setting Range
-100.00% ~100.0%
b5-09
Second point input value of AI1
Default
10.00V
Setting Range
0.00 V~10.00 V
b5-10
Corresponding setting of second point input value of AI1
Default
100.0%
