Function Parameters
9-41
AC10 Inverter
the AI1 channel voltage is lower than 0.5V.
F745 Threshold of pre-alarm overheat (%) Setting range: 0~100
Mfr’s value: 80
F747 Carrier frequency auto-adjusting
Setting range:
0: Invalid
1: Valid
Mfr’s value: 1
When the temperature of the heatsink reaches the value of 95
℃
X F745 and multi-function output
terminal is set to 16 (refer to F300~F302), it indicates inverter is in the status of overheat.
When F747=1, the temperature of the heatsink reaches 86
℃
, inverter carrier frequency will
adjust automatically, to decrease the temperature of inverter. This function can avoid overheat
malfunction.
When F159=1, random carrier frequency is selected, F747 is invalid.
F754 Zero-current threshold (%)
Setting range: 0~200
Mfr’s value: 5
F755 Duration time of zero-current (S)
Setting range: 0~60
Mfr’s value: 0.5
When the output current has fallen to zero-current threshold, and after the duration time of
zero-current, ON signal is output.
