Determining The Current Torque Of A Drive - HEIDENHAIN iTNC 530 HSCI Technical Manual

6.11.11 Determining the current torque of a drive

920
With Module 9170 you can determine the averaged, maximum and minimum
torque of a drive.
The information about the torque utilization always refers to the values
determined between two PLC cycles. The momentary torque is returned in
tenths of per cent of the nominal torque.
Example:
For the first axis (e.g. X axis and QSY 190D EcoDyn with M
averaged torque of 281 is determined via Module 9170.

Module 9170 Find the current torque
Module 9170 makes the averaged, maximum and minimum load values of the
drive of an axis available between two PLC cycles as a reference value for the
rated torque value or rated power. One mode also supplies the algebraic sign
of the averaged load.
Call:
PS B/W/D/K <Axis>
Axis-specific: Dependence on MP4020 bit 14
PS B/W/D/K <Mode>
0: Torque value in per cent of the rated torque
1: Torque value in tenths of per cent of the rated torque
2: Torque value in tenths of per cent of the rated torque with
algebraic sign; minimum and maximum torque will not be
calculated (=0)
