I have two different 8-wire steppers in parallel configuration with two different Leadshine digital drives. I'm looking for to match my driver current settings with motor specs.
Dip switch settings of the driver are printed in DM556 as Peek and RMS , in DM860 as Peek and Ref. Which one I should match with my motor rated current, Peak or Ref/RMS? For max performance obviously
I have read some posts about this subject, but haven't found clear answer. Votes are like 50/50.... Peak/RMS
My hardware:
Motor1, PK299-E4.5A (RATED CURRENT A/PHASE)
Bipolar (Parallel) 6.2A
Bipolar (Series) 3.18A
Unipolar 4.5ADM860 DIGITAL DRIVER
REF Current - Peak Current
......
4.28A ---- 5.14A
4.86A ----- 5.83A
5.43A ----- 6.52A
6.00A ----- 7.20AMotor2,
M60STH88 (RATED CURRENT A / PHASE)
Bipolar (Parallel) 4.2A
Bipolar (Series) 2.1A
Unipolar 3ADM556 DIGITAL DRIVER
Peak Current - RMS Current
.....
3.8A ----- 2.7A
4.3A ----- 3.1A
4.9A ----- 3.5A
5.6A ----- 4.0A
Leadshine manual is also writing:
"Parallel ConnectionsAn 8 lead motor in a parallel configuration offers a more stable, but lower torque at lower speeds. But because of the lower inductance, there will be higher torque at higher speeds. Multiply the per phase (or unipolar) current rating by 1.96, or the bipolar current rating by 1.4, to determine the peak output current."
