VFD CX

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

Click the VFD_Configuration_screen button on the left pane to open the VFD Configuration screen.
Enter information into available fields.
Click Commit to save the settings or Reset to revert to the last saved settings.
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 non-volatile memory of the frequency converter, 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 non-volatile memory of the frequency converter, 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 non-volatile memory of the frequency converter, 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 non-volatile memory of the frequency converter, unless bit 4 in nciEeprSave has been set to 1.
