Keypad
The Keypad makes up a complete interface for control and programming of the frequency converter. The Keypad is detachable and can be installed up to 10ft/
3M from the frequency converter, i.e. in a front panel with the optional Remote Keypad Mounting Kit (RMKYPDAC)..
Logic Controller (LC)
The LC is a sequence of user defined actions executed when the associated user defined events are evaluated as true by the Logic Controller. (Parameter group
LC-##).
lsb
Least significant bit.
msb
Most significant bit.
MCM
Short for Mille Circular Mil, an American measuring unit for cable cross-section. 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 Keypad.
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 OPCENC.
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. F-37
Adv. Switching Pattern
).
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..
STW
Status Word
Drive Standard Bus
Includes RS 485 bus with Drive protocol or MC protocol. See par. O-30
Protocol
.
Thermistor:
A temperature-dependent resistor placed where the temperature is to be monitored (frequency converter or motor).
THD
Total Harmonic Distortion state the total contribution of harmonic.
Trip
A state entered in fault situations, e.g. if the frequency converter is subject to an over-temperature or when the frequency converter is protecting the motor,
process or mechanism. Restart is prevented until the cause of the fault has disappeared and the trip state is cancelled by activating reset or, in some cases, by
being programmed to reset automatically. Trip may not be used for personal safety.
Trip Locked
A state entered in fault situations when the frequency converter is protecting itself and requiring physical intervention, e.g. if the frequency converter is subject
to a short circuit on the output. A locked trip can only be cancelled by cutting off mains, removing the cause of the fault, and reconnecting the frequency converter.
Restart is prevented until the trip state is cancelled by activating reset or, in some cases, by being programmed to reset automatically. Trip may not be used for
personal safety.
