Coordinated multi-axis system

In a coordinated multi-axis system, the motion sequences are in a permanently time-defined rela-

tionship (e.g. applications with cams or clock-related systems).

• In the DSD, you can optimally dimension a multi-axis system with coordinated drive axes relat-

ing to energy.

• Lenze BlueGreen Solutions serves to calculate amortisation times quickly. The cost-cutting po-

tentials are documented in an Energy Performance Certificate.

[7-194] Power characteristic of two coordinated drive axes

Uncoordinated multi-axis system

Uncoordinated motion sequences are not associated with regard to time. Even if only single drive

axes of the multi-axis system are uncoordinated, the DSD calculates with the most unfavourable

power characteristic:

• The peak powers of all single axes occur at the same time.

• The supply components of the network must provide the sum of peak powers in generator

mode and in motor mode of all drive axes.

[7-195] Power characteristic for two uncoordinated drive axes

 Power characteristic drive axis 1

 Power characteristic drive axis 2

 Total power

 Power characteristic drive axis 1

 Power characteristic drive axis 2

The determination of the total power is not possible because there is no relationship between the power character-

istics.
