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
2
.
On-line/off-line parameters
Changes to on-line parameters are activated immediately after the data value is changed. To activate changes to offline parameters,
press [OK].
Process PID
The PID control maintains speed, pressure, and temperature by adjusting the output frequency to match the varying load.
PCD
Process control data.
Power cycle
Switch off the mains until the display (LCP) is dark, then turn power on again.
Power factor
The power factor is the relation between I
1
and I
RMS
.
For this drive, , therefore:
The power factor indicates to which extent the drive imposes a load on the mains supply.
The lower the power factor, the higher the I
RMS
for the same kW performance.
In addition, a high power factor indicates that the different harmonic currents are low.
The built-in DC coils produce a high power factor, minimizing the imposed load on the mains supply.
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.
Setup
Save parameter settings in 2 setups. Change between the 2 parameter setups and edit 1 setup while the other setup is active.
SFAVM
Acronym describing the switching pattern stator flux-oriented asynchronous vector modulation.
Slip compensation
The drive compensates for the motor slip by giving the frequency a supplement that follows the measured motor load, keeping the
motor speed almost constant.
