The DM542 is a versatility fully digital stepping drive based on a DSP with advanced control algorithm. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. The Self-test and auto-configuration technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives in the markets. Its unique features make the DM556 an ideal solution for applications that require low-speed smoothness.

Microstep resolutions and output current are programmable, the former can be set from full-step to 102,400 steps/rev and the latter can be set from 0.5A to 5.6A.
However, when it's not in software configured mode, this drive uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as shown below:
Microstep Resolution Selection
When it's not in software configured mode, microstep resolution is set by SW5, 6, 7, 8 of the DIP switch as shown in the following table:
| Microstep | Steps/rev.(for 1.8o motor) | SW5 | SW6 | SW7 | SW8 |
| 1 to 512 | Default/Software configured | on | on | on | on |
| 2 | 400 | off | on | on | on |
| 4 | 800 | on | off | on | on |
| 8 | 1600 | off | off | on | on |
| 16 | 3200 | on | on | off | on |
| 32 | 6400 | off | on | off | on |
| 64 | 12800 | on | off | off | on |
| 128 | 25600 | off | off | off | on |
| 5 | 1000 | on | on | on | off |
| 10 | 2000 | off | on | on | off |
| 20 | 4000 | on | off | on | off |
| 25 | 5000 | off | off | on | off |
| 40 | 8000 | on | on | off | off |
| 50 | 10000 | off | on | off | off |
| 100 | 20000 | on | off | off | off |
| 125 | 25000 | off | off | off | off |
Current Settings
When it's not in software configured mode, the first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor's required current.
| Peak Current | RMS Current | SW1 | SW2 | SW3 |
| Default/Software configured (0.5 to 5.6A) | OFF | OFF | OFF | |
| 1.0A | 0.71A | ON | OFF | OFF |
| 1.6A | 1.04A | OFF | ON | OFF |
| 1.91A | 1.46A | ON | ON | OFF |
| 2.37A | 1.69A | OFF | OFF | ON |
| 2.84A | 2.03A | ON | OFF | ON |
| 3.34A | 2.36A | OFF | ON | ON |
| 4.2A | 3.0A | ON | ON | ON |
Note: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed condition.
