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.
