M5645 4.5A128 Micro Step 57 86 Two-Phase Stepper Motor Driver Replacing M542 / 2M542

Description:
- 42,57,86,110,4.5A fit within the two-phase / four-phase / four-wire / six-wire stepper motor;
- Independent power field pipe structure,
- Using ARM-Cortex Dsp chip32-bit kernel as the master;
- Advanced H-bridge bipolar constant phase flow drive;
- Chopper parameter auto-tuning,Automatic detection of the motor and the power supply voltage and generates a matching optimization chopperParameters;
- Dynamic freewheeling control technology,Dynamically adjusting the motor speed control damping freewheeling speed ratio, increase the motor speed step accuracy, improve power efficiency, reduce the output current frequency ripple which reduces motor heating silicon steel magnetic eddy current losses lead to motor (motor "Iron Loss ");
- Current 1-4.5A8 filesAdjustable, 0.5A increments;
- Working voltage range20-56V,56V supply voltage can work reliably;
- 16 file segments: full step, half step, 1/4-step, step 1/8, 1/16-step, 1/32-step, 1 /64,1 / 128 steps,Step 1/5, 1/10-step, 1/15-step, 1/20 steps, 1/25-step, 1/30 steps, 1 /40,1 /50 steps,Up to 128 segments;
- Automatic semi-flow function;
- Offline / enable control;
- Optocoupler isolation input signal;
- Independent power terminals, easy to use;
- Overheat protection;
- Wrong phase and short circuit protection;
- Stepping up to the maximum pulse frequency200KHZ;
- TVS diode transient power surge protection;
- Independent power terminals for easy wiring.
- The drive power output using eight independent high-power field pipe, 8:00 cooling, for high current drive, it is particularly important. The use of low-cost integrated single-chip driver control circuit sucked and eight power tubes are all integrated in a dozen square millimeter chip silicon core, the heat is highly concentrated, resulting in premature aging chip life.

Instructions:
- Run current regulation (Running Current)
- Use DIP switchesSW1, SW2,SW3 adjust the operating current.

  SW1   SW2   SW3   CURRENT
  OFF   OFF   OFF   1.0A
  OFF   OFF   ON   1.5A
  OFF   ON   OFF   2.0A
  OFF   ON   ON   2.5A
  ON   OFF   OFF   3.0A
  ON   OFF   ON   3.5A
  ON   ON   OFF   4.0A
  ON   ON   ON   4.5A

Holding Current (automatic semi-flow)(Holding Current)
- Use DIP switchSW4 adjusted to keep current.When the motor stopped holding time (0.5 seconds without input step pulse), SW4 =OFF, the motor current is reduced by half, SW4 =ON, not half.

  SW4   Holding Current
  ON   Full Current (full flow)
  OFF   Half Current(semi-flow mode)

Subdivision adjustment (Microstep)
DIP switch SW5, SW6, SW7, SW8 used to adjust the motor subdivision mode, a total of 16 kinds of sub-modes:

SW5 SW6 SW7 SW8 PULSE/REV MICROSTEP
OFF OFF OFF OFF 200 1
OFF OFF OFF ON 400 2
OFF OFF ON OFF 800 4
OFF OFF ON ON 1600 8

Signal inputs:
- PUL +: pulse signal + pole
- PUL-: pulse signal - pole

- DIR +: direction control signal + pole
- DIR-: direction control signal - pole

- ENA +: + enable signal pole
- ENA-: enable signal - pole

Note:Offline enable a Reset signal and the other two signals, users can not connect, when that is no signal input, it is to enable the driver to enter the working mode; if a signal is input, the drive will go into sleep mode.

Control signal PC controller can be active high and to be active low. When the high effective, all the negative terminal of the control signal as the signal ground connected together, when active low, all the positive terminal of the control signals together as a signal common terminal.

Note:Signal VCCValue5VWhen,RShort (no series resistor R);

Signal VCCValue12VWhen,RTo1K ~ 1.2KGreater than1 / 8WResistance;

Signal VCCValue24VWhen,RTo2.7K ~ 3.3KGreater than1 / 8WResistance;

Output and power ports:
DC +: connect the power + pole
DC-: take power - pole
A +, A- then stepping motors A phase
B +, B- then stepping motors B phase
