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 pulse transmitter used for feeding back information on motor speed. The encoder is used in applications where great accuracy in

speed control is required.

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

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..

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)

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).

STW

Status Word

FC Standard Bus

Includes RS 485 bus with FC protocol or MC protocol. See par. 8-30

Protocol

Thermistor:

A temperature-dependent resistor placed where the temperature is to be monitored (frequency converter or motor).

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.

VT Characteristics

Variable torque characteristics used for pumps and fans.

VVC

plus

If compared with standard voltage/frequency ratio control, Voltage Vector Control (VVC

plus

) improves the dynamics and the stability, both when the speed

reference is changed and in relation to the load torque.
