– Setting PID Parameters; Proportional Gain (Bn-17) and
Integral Time (Bn-18)
•
After all external connections have been made and the protective covers have been
replaced,
power up
the inverter
but do not run at this point
.
•
Parameters
Bn-17 = 1.0
(
Proportional Gain
) and
Bn-18 = 10.0s
(
Integral Time
) are factory
set to the values shown. However, a good starting point for these values is setting the
Proportional Gain Bn-17 = 2.0
and the
Integral Time
Bn-18 = 5.0s
. To change these
parameters, follow the keypad navigation procedure below.
