Tests in DSD

DSD carries out all tests for a safe dimensioning. Here, the following product-specific and proce-

dure-specific factors for utilisation and overdimensioning are assumed regarding application, mo-

tor and inverter.

• VFCplus with VVC (only possible with Servo Drives 9400)

• The motor is only utilised to the rated torque.

• The rated output current of the inverter is at least 120 % of the rated motor current.

• VFCplus (possible with all inverters)

• The motor is maximally utilised to 75 % of the rated torque.

• The rated output current of the inverter is at least 170 % of the rated motor current.

• Compared to the requirement of the application, the inverter is overdimensioned with an

overall factor of 2.27.

 Note!

Observe the notes in the dimensioning protocol if

• limit values have been exceeded,

• dimensioning has been carried out with Servo Drives 9400 and the control type VFC-

plus with VVC.

• In order to activate VVC (Voltage Vector Control), parameters must be adapted in

the controller.
