Table 8.1: Electrical/general specifications
CONTROL METHOD  Voltage source.
 Type of control:
- V/f (Scalar).
- VV W: Voltage Vector Control.
- Sensorless vector control (without encoder).
 PWM SVM (Space Vector Modulation).
 Full digital (software) current, flux, and speed regulators.
Execution rate:

OUTPUT
FREQUENCY
 0 to 3.4 x rated motor frequency (P0403). The rated motor frequency
is programmable from 0 Hz to 300 Hz in the V/f and V VW modes and
from 30 Hz to 120 Hz in the vector mode.
 Maximum output frequency limit according to the switching frequency:
- 125 Hz (switching frequency = 1.25 kHz).
- 200 Hz (Switching frequency = 2 kHz).
- 250 Hz (switching frequency = 2.5 kHz).
- 500 Hz (switching frequency ≥ 5 kHz).
PERFORMANCE SPEED
CONTROL
V/f (Scalar):
 Regulation (with slip compensation): 1 % of the rated speed.
 Speed variation range: 1:20.
VVW:
 Regulation: 1 % of the rated speed.
 Speed variation range: 1:30.
Sensorless:
 Regulation: 0.5 % of the rated speed.
 Speed variation range: 1:100.
PERFORMANCE TORQUE
CONTROL
 Range: 10 to 180 %, regulation: ±5 % of the rated torque (with encoder).
 Range: 20 to 180 %, regulation: ±10 % of the rated torque (sensorless
above 3 Hz).
