4. Configuració

4.1 Connexions de cablejat

Proper wiring is crucial for the driver's functionality and safety. Refer to the labels on the driver for correct terminal connections.

• Entrades de senyal:
  • DIR+: Direction signal positive input.
  • DIR-: Direction signal negative input.
  • PUL+: Pulse signal positive input.
  • PUL-: Pulse signal negative input.
  • ENA+: Enable signal positive input.
  • ENA-: Enable signal negative input.
• Connexions del motor:
  • A+, A-: Connect to one coil of the 2-phase stepper motor.
  • B+, B-: Connect to the second coil of the 2-phase stepper motor.
• Font d'alimentació:
  • ACØ, ACØ: Connect to the AC power source (18-80V AC).
  • Alternatively, connect to a DC power source (24-110V DC). Ensure correct polarity.

4.2 Configuració del commutador DIP

The MA860H uses DIP switches to configure the output current and microstep resolution. The switches are labeled SW1 to SW8.

4.2.1 Current Setting (SW1, SW2, SW3)

Use switches SW1, SW2, and SW3 to set the desired peak output current for the motor. SW4 controls the half/full current mode.

SW4 Setting:

• ON: Half Current (reduced reactive current)
• OFF: Full Current

4.2.2 Microstep Setting (SW5, SW6, SW7, SW8)

Use switches SW5, SW6, SW7, and SW8 to set the desired microstep resolution (pulses per revolution).

5. Instruccions de funcionament

Once the driver is correctly wired and configured, apply power. The driver will enter an idle state. Provide pulse signals to the PUL+ and PUL- inputs to initiate motor movement. The direction of rotation is controlled by the DIR+ and DIR- inputs. The ENA+ and ENA- inputs can be used to enable or disable the motor output.

Ensure that the control signals (PUL, DIR, ENA) are within the specified voltage range (5V-24V) for TTL compatibility.

6. Manteniment

The MA860H driver is designed for reliable operation with minimal maintenance. However, adhering to the following guidelines can prolong its lifespan:

• Keep the driver clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Ensure adequate ventilation around the driver, especially around the heatsink and fan, to prevent overheating.
• Comproveu regularment totes les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast o corrosió.
• Operate the driver within its specified environmental conditions (temperature, humidity).
