How to optimize stepper performance using Chinese driver DQ542MA

Hello, I am trying to determine the optimal configuration in terms of micro stepping and the sort of IPM performance I can expect.

Currently my motors are stalling at 200 IPM without being connected to a machine and I am not sure if that is the best it can do.

Here is what I have:

DQ542MA driver, 48v 8.3amp power supply, 270 oz 2.8amp stepper, P4 machine with XP and MACH 3

Specs for DQ542MA.

Current max IPM @ 1/2 steps= 400 steps/per rev, 1/8 steps=1600 steps/rev, or 1/16 steps= 3200 steps/per rev is about 170 with acceleration ranging from 30 to 50.

Any help would be appreciated.

Thx.

You should do it attached to whatever you are trying to drive. The max speed depends on the load. It does not make sense to tweak the settings on the motor alone.

Thanks H500. I should have been more clear.

Max IPM is 170 with load of an X axis with a 10 pitch ballscrew. Max IPM with no load is 200. Acceleration ranging from 30 to 50

170 ipm is respectable. On my SX3, the x-axis can do about 250 ipm with 5tpi ball screws, but I normally set it to 100.

One more thing to consider - based on the photograph, it looks like you might be using 6-wire motors (because it appears that the motor has a 6-pin connector).

There are two different ways to hook up a 6-wire motor to a bipolar driver such as the DQ542MA - either a full-coil hookup or a half-coil hookup. If you are using a full-coil hookup, and the inductance of the motor is relatively high, then you may find that changing to a half-coil hookup may permit you to get greater torque at a higher speed (neglecting other possible reasons for motor stalling or drop-off in torque, such as "mid-band resonance").
