LCP
The Local Control Panel (LCP) makes up a complete interface for control and programming of the
adjustable frequency drive. The control panel is detachable and can be installed up to 9.8 ft (3
meters) from the adjustable frequency drive, i.e. in a front panel by means of the installation kit
option.
The local control panel is available in two versions:
- Numerical LCP101 (NLCP)
- Graphical LCP102 (GLCP)
lsb
Least significant bit.
MCM
Short for Mille Circular Mil, an American measuring unit for cable cross-section. 1 MCM 0.00079≡
in.
2
(0.5067 mm
2
).
msb
Most significant bit.
NLCP
Numerical Local Control Panel LCP101
Online/Offline Parameters
Changes to online parameters are activated immediately after the data value is changed. Changes
to offline parameters are not activated until you enter [OK] on the LCP.
PID Controller
The PID controller maintains the desired speed, pressure, temperature, etc. by adjusting the out-
put frequency to match the varying load.
RCD
Residual Current Device.
Set-up
You can save parameter settings in four set-ups. Change between the four parameter set-ups and
edit one while another set-up is active.
SFAVM
Switching pattern called
Stator Flux-oriented Asynchronous Vector Modulation (par. 14-00).
Slip Compensation
The adjustable frequency drive compensates for the motor slip by giving the frequency a supple-
ment that follows the measured motor load, thus keeping the motor speed almost constant.
Smart Logic Control (SLC)
The SLC is a sequence of user-defined actions executed when the associated user-defined events
are evaluated as true by the SLC.
