Factory Configuration

Factory settings

The Altivar 28 is factory-set for the most common operating conditions :
- Display : speed controller ready (when stopped), motor frequency (when running)
- Nominal motor frequency: 50 Hz
- Motor voltage : 230V or 400V, depending on product
- Ramps : 3 seconds
- Low speed : 0 Hz
- High speed : 50 Hz
- Frequency loop gain : standard
- Motor thermal current = nominal speed controller current
- Standstill injection braking current = 0.7 x nominal speed controller current, for 0.5 seconds
- Constant torque operation, with sensorless flux vector control
- Automatic adaptation of the deceleration ramp in the event of overvoltage on braking
- Switching frequency 4 kHz
- Logic inputs :
• LI1, LI2 : 2 directions of operation, 2-wire control on rising edge
• LI3, LI4 : 4 preset speeds (0 Hz, 10 Hz, 15 Hz, 50 Hz)
- Analog inputs :
• AI1 (0 + 10 V) : speed reference
• AI2 (0 + 10 V) or AIC (0, 20 mA) : summing AI1
- Relay R2 :
• speed reference reached
- Analog output AO (0 - 20 mA) :
• motor frequency
If the above values are compatible with the application, the speed controller can be used without
changing the settings.
Labels
The speed controller is supplied with labels in the cover :
• 1 label fixed inside the cover : wiring diagram
• 3 self-adhesive labels to be fixed near the speed controller if required : programming of the main
parameters, meaning of the fault codes and customer settings (blank label)
