3.4 PD42-1270 Torque Curves
The following diagrams show the torque vs. speed curves for the PD42-1-1270, the PD42-2-1270, and
the PD42-3-1270 at three different typical conditions. All measurements have been done in spreadCycle
chopper mode. The measurement conditions are:
1. V DD =+24V, I
COILRM S
=1A, 1/256 microstepping
2. V DD =+24V, I
COILRM S
=1A, half stepping
3. V DD =+12V, I
COILRM S
=1A, half stepping
