Configuring VFDNX Drive Parameters

Use the VFD NX configuration screen to configure the motor parameters, transmission controller parameters, and EEPROM saving option parameters.

Mode

These parameters can be configured in both Off-line and On-line modes from the wizard.

Procedure

  1. Click the VFDNX_Configuration_screen button on the left pane to open the VFD Configuration screen.
  2. Enter information into available fields.
  3. Click Commit to save the settings or Reset to revert to the last saved settings.

 Description
Maximum Speed
 -163.84 163.83 100.0% Maximum motor speed

The value of the maximum speed must be validated against the value of the minimum speed as follows:

-163.840 <= minimum speed <=

maximum speed <= 163.830
Minimum Speed
 -163.84 163.83 0.0% Minimum motor speed

The value of the minimum speed must be validated against the value of the maximum speed as follows:

-163.84 <= minimum speed <=

maximum speed <= 163.83
Nominal Speed
 300 20000 1725 RPM

3450 RPM

1140 RPM		 Nominal motor speed in RPM. Find this value on the rating plate of the motor.

This configuration property is used to provide the nominal speed of the motor in RPM. This value is necessary to determine the minimum and maximum speed for the motor, based on the configuration properties nciMinSpeed, nciMaxSpeed (entered as percent of nominal speed).
Nominal Frequency
 30 320 60 Hz

50 Hz		 Nominal motor frequency

This configuration property is used to provide the nominal frequency for the motor.
Acceleration Time
 0.1 3000.0 30 sec Minimum ramp up time.

Defines the acceleration time for Vacon NX
Deceleration Time
 0.1 3000.0 30 sec Minimum ramp down time.

Defines the deceleration time for Vacon NX
Default Drive Speed Scale
 -163.84 163.83 0% Default value for nviDrvSpeedScale. It provides scaling for nviDrvSpeedStpt. Negative values of nviDrvSpeedScale indicate reverse (anti clockwise) direction of motor rotation.

This value will be adopted at power-up and in case of not receiving any input variable within the specified Receive Heartbeat time.
