LCP
The Local Control Panel (LCP) makes up a complete interface for control and programming of the
frequency converter. The control panel is detachable and can be installed up to 3 metres from the
frequency converter, 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 0.5067
≡
mm
2
.
msb
Most significant bit.
NLCP
Numerical Local Control Panel LCP101
On-line/Off-line Parameters
Changes to on-line parameters are activated immediately after the data value is changed. Changes
to off-line 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 Set-up, while another Set-up is active.
SFAVM
Switching pattern called S tator F lux oriented A synchronous V ector M odulation (par. 14-00).
Slip Compensation
The frequency converter compensates for the motor slip by giving the frequency a supplement
that follows the measured motor load 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.
Thermistor:
A temperature-dependent resistor placed where the temperature is to be monitored (frequency
converter or motor).
