Configuring VFD CX Settings

Use the VFD Configuration Screen to configure the motor parameters, transmission controller parameters, and EEPROM saving option parameters.

Mode

Off-line or On-line.

Procedure

  1. Click the VFD_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.
  4. Click Next to open the Advanced VFD Configuration Screen.

Fields

Point Name Min. Value Max. Value Typical Values Description
Maximum speed 0 100% 100% Maximum motor speed

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

0 <= minimum speed <=  maximum speed <= 100

If the value is changed via the network it is not saved in the frequency converter’s non-volatile memory, unless bit 1 in nciEeprSave has been set to 1.
Minimum Speed 0 100% 0.0% Minimum motor speed

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

0 <= minimum speed <= maximum speed <= 100

If the value is changed via the network it is not saved in the frequency converter’s non-volatile memory, unless bit 0 in nciEeprSave has been set to 1.
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. 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). If the value is changed via the network it is not saved in the frequency converter’s non-volatile memory, unless bit 5 in nciEeprSave has been set to 1.
Nominal frequency 30 500 60 Hz

50Hz		 Nominal motor frequency

This configuration property is used to provide the nominal frequency for the motor. If the value is changed via the network it is not saved in the frequency converter’s non-volatile memory, unless bit 4 in nciEeprSave has been set to 1.
