Initializing
If initialization is carried out (par. 14-22
Intermittent Duty Cycle
An intermittent duty rating refers to a sequence of duty cycles. Each cycle consists of an on-load and an off-load period. The operation can be either
periodic duty or non-periodic duty.
LCP
The Local Control Panel 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 10 ft [3 m] from the adjustable frequency drive, i.e., in a front panel by means of the installation kit option.
NLCP
Numerical Local Control Panel interface for control and programming of adjustable frequency drive. The display is numerical and the panel is basically
used for display process values. The NLCP has no storing and copy function.
lsb
Least significant bit.
msb
Most significant bit.
MCM
Short for Mille Circular Mil, an American measuring unit for cable cross-sections. 1 MCM = 0.5067 mm
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.
Process PID
The PID regulator maintains the desired speed, pressure, temperature, etc. by adjusting the output frequency to match the varying load.
PCD
Process Data
Pulse Input/Incremental Encoder
An external digital sensor used for feedback information of motor speed and direction. Encoders are used for high speed accuracy feedback and in high
dynamic applications. The encoder connection is either via term 32 and 32 or encoder option MCB 102.
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 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 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 Smart Logic Controller.
(Parameter group 13-xx Smart Logic Control (SLC).
STW
Status Word
FC Standard Bus
Includes RS 485 bus with FC protocol or MC protocol. See par. 8-30
