Function:
Select among different units to be shown on the display.
The unit is read out if an LCP control unit can be
connected, and if Reference [unit] [2] or Feedback [unit]
[3] has been selected in one of parameters 009-012
Display read-out, and in Display mode. The unit is used
in Closed loop also as a unit for Minimum/Maximum
reference and Minimum/Maximum feedback.
Description of choice:
Select the required unit for the reference/feed-
back signal.
NOTE
Parameters 417-421 are only used, if in
parameter 100 Configuration the selection
made is Speed regulation, closed loop [1].
417 Speed PID proportional gain
(SPEED PROP GAIN)
Value:
0.000 (OFF) - 1.000
Function:
Proportional gain indicates how many times the
fault (deviation between the feedback signal and
the setpoint) is to be amplified.
Description of choice:
Quick regulation is obtained at high amplification,
but if the amplification is too high, the process may
become unstable in the case of overshooting.
