I have two different 8-wire steppers in parallel configuration with two different Leadshine digital drives at 1/8 microsteps. 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 4.5A	DM860 DIGITAL DRIVER REF Current - Peak Current ...... 4.28A ---- 5.14A 4.86A ----- 5.83A 5.43A ----- 6.52A 6.00A ----- 7.20A
Motor2, M60STH88 (RATED CURRENT A / PHASE) Bipolar (Parallel) 4.2A Bipolar (Series) 2.1A Unipolar 3A	DM556 DIGITAL DRIVER Peak Current - RMS Current ..... 3.8A ----- 2.7A 4.3A ----- 3.1A 4.9A ----- 3.5A 5.6A ----- 4.0A

Thank's!

Hi Kmin
The peak current =1.3*RMS ,normally ,we set RMS for the motor
For your motor 1 ,PK299-E4.5A ,and if the connection type is parallel ,the current setting on DM860 should be 6.00A ----- 7.20A
For motor 2 .the DM556 current setting is 5.6A ----- 4.0A (for parallel connection)
