DM556 is a high performance micro stepping driver based on sinusoidal current control technology. Thanks to this technology and the function of automatic adjustment to the motor (current self-regulation parameters), low noise and heating levels, smooth movement and the best performance at high speeds are achieved compared to most drivers on the market. Designed to work with 2-phase and 4-phase hybrid stepper motors.
• Supply voltage up to +45 VDC.
• Output current up to 5.6A
• Auto-tuning function for motor
• Sinusoidal current control technology
• Input pulse frequency up to 200 kHz
• TTL compatible opto-isolated inputs
• Automatic current reduction in hold mode
• Control of 2-phase and 4-phase motors
• Support for PUL/DIR and CW/CCW modes
• Protection against voltage surges, short circuits and overcurrents
The driver is suitable for a wide range of stepper motors from 17 to 34 NEMA. Used with various kinds of machine tools such as XY tables, engraving machines, labeling machines, laser cutting machines, transfer machines, etc. Extremely well suited for applications requiring low noise, low heat, high speed and accuracy.
The driver uses an 8-bit DIP switch to set the microstep resolution and motor operating current:
SW 1 ┐ SW 2 ├─ Operating current SW 3 ┘ SW 4 ── Holding current (50%/100%) Motor auto-identification and parameter auto-tuning (2 changes/sec) SW 5 ┐ SW 6 │ SW 7 ├─ Microstep resolution SW 8 ┘
Setting the operating current, first three DIP switches (SW1, 2, 3):
Peak current, A RMS current, A SW1 SW2 SW3 Default / software setting (0.5 to 5 .6 A) off off off 2.1 1.5 on off off 2.7 1.9 off on off 3.2 2.3 on on off 3.8 2.7 off off on 4.3 3.1 on off on 4.8 3.5 off on on 5.6 4.0 on on on
Setting the holding current with switch SW4.
In the OFF position, the holding current is set to 50% of the operating value,
in the ON position, it is set equal to the selected value of the operating current.
Microstep mode selection is set by DIP switches SW5, 6, 7, 8 as shown in the table:
