IV-1. Special power supply
IV-1-1. E00=8: variable frequency power
P03 PID given signal selection, you can set through the keyboard, analog AI2, pulse and other
means to set a given voltage.
Given voltage is calculated as follows:
Given voltage:220VAC
Given voltage setting =220*1.414/500*100%=62.2%
Frequency Power specific parameters:
In regulated power supply mode, the output and input voltage are both adjustable.
The increasing time and decreasing time of output voltage is adjusted by F09 and F10.
E16 is the voltage increasing time, the definition of the output voltage increasing time is
from9999 corresponds to 999.9 seconds.
E17 is the voltage decreasing time, the definition of the output voltage decreasing time is
from9999 corresponds to 999.9 seconds.
Voltage increasing/decreasing time just used to adjust the accelerate/decelerate time of
output frequency when the inverter running.
After the stopping command issued, the controller will stop the frequency output when the
output frequency decelerate to 0hz.
For safety and reliability to ensure that the output voltage to bear the load within the
system, we need to define the maximum output voltage of the system.
If the system highest withstand voltage 250VAC，then a maximum outout voltage=
250；E18=250。
