GE af-600 fp

DSP
Digital Signal Processor.
Relay Outputs:
The frequency converter features two programmable Relay Outputs.
Electronic Thermal Overload
Electronic Thermal Overload is a thermal load calculation based on present load and time. Its purpose is to estimate the motor temperature.
Initialising
If initialising is carried out (par. H-03 Restore Factory Settings), the programmable parameters of the frequency converter return to their default settings.
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 none-periodic duty.
keypad
The keypad makes up a complete interface for control and programming of the frequency converter. The 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.
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.
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.
PID Controller
The PID controller maintains the desired speed, pressure, temperature, etc. by adjusting the output 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
Stator Flux oriented Asynchronous V ector M odulation (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.
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 LC.
Thermistor:
A temperature-dependent resistor placed where the temperature is to be monitored (frequency converter or motor).
