P1.6 489 Motor Nom Speed 1,2,3 RW
Use this parameter to set the Motor Rated Speed.
P1.7 490 Motor PF 1,2,3 RW
Use this parameter to set the Power factor cos phi of the motor.
P1.8 487 Motor Nom Voltage 1,2,3 RW
Use this parameter to set the motor rated voltage.
P1.9 488 Motor Nom Frequency 1,2,3 RW
The rated frequency of the motor. This is the frequency at which ”Motor Nom Voltage” is applied to
the motor. Below this frequency, the applied motor voltage will be reduced. Above this frequency the
voltage remains limited to ”Motor Nom Voltage”
P1.10 2465 HOA Source 1,2,3 RW
Use this parameter to enables the HOA control function. If enabled it selects the desired location for
switching between Hand, Off, and Auto control locations.
0 - I/O terminal/Keypad/Fieldbus - Controlled by either control terminals, keypad or fieldbus location.
1 - Keypad - Drive is looking for control source location from the keypad Hand/OFF/AUTO buttons only.
2 -I/O Terminal - Drive is looking at the control terminals only for the control place selection.
3 - Fieldbus - Drive is looking at the Feildbus control selection only for the control place selection.
P1.11 1695 Hand Control Place 1,2,3 RW
Selects where the drive will look for the start command in the "Hand" location.
• I/O terminal Start 1 and 2 would be from the Digital hardwired inputs assigned via the input group
• Fieldbus would be from a communication bus.
• Keypad would be from the Start/Stop buttons on the keypad.
