PDM20 Series
-35-
In initial use, confirm the rotation direction of motor. Exchange arbitrary two lines
of output power line U, V, W of the SPD or modify parameter P0.02 to change the
rotation direction of the motor.
P0.06
Proportional
gain
0.0～100.0 % 20
The larger the parameter, the faster the response
speed of the pressure system. However, when it
is set too big, the system will oscillate. Adjust it
according to different water supply system.
Adjustment method:
If factory parameters can’t meet demands, adjust parameters finely. First increase
proportional gain to make sure that the system will not oscillate.
Note: improper parameter setting of P0.06 will cause huge speed overshoot, and
even over voltage fault in overshoot back.
