Consideration Of I0 When Using Synchronous Motors; Module 9166 Momentary Utilization Of The Drive Motor - HEIDENHAIN iTNC 530 HSCI Technical Manual

July 2013

Consideration of I0 when using synchronous motors:

If I0 differs too much from Irated, then the utilization display can be adapted
via MP2312.x. In this case you must set MP2312.x = I
Example for the behavior of I0 and Irated with an OSY155F-EcoDyn motor:
12
10
8
6
4
2
0
0 500
In the diagram you can see that:
I0 = 12.8 A, Irated = 9.8 A, nRated = 3000 rpm
For the synchronous motor:
Mactl = kT · Iactl
Mrated = kT · Irated
Mrated = f(n)

Module 9166 Momentary utilization of the drive motor

The evaluation through MP2312.x is already calculated in the utilization of the
drive motor.
