The Cloudray 3DM580S is a digital step servo drive designed for industrial applications, offering enhanced performance over traditional analog stepper drives. It is built on a 32-bit DSP platform developed by TI and incorporates micro-stepping technology and a PID current control algorithm. This design results in low noise, low vibration, low heating, and high-speed, high-torque output, making it suitable for a wide range of stepper motors. The 3DM580S also features S-shape acceleration/deceleration for pulse trains and can trigger motor start-stop operations using normal switching values.
Function Description:
The 3DM580S drive operates in a constant current control mode, converting input power into a PWM chopping wave to deliver voltage to the motor. This process means the input power significantly influences the drive's performance. The drive supports various pulse modes, including Direction & Pulse, CW/CCW double pulse, and A/B orthogonal pulse. It also includes a 2MHz digital signal filter for pulse filtering and automatically halves the current when the motor stops running, reducing heat generation.
A key feature is its resonance suppression, which automatically calculates resonance points and inhibits intermediate frequency (IF) vibration. The drive also includes parameter adaptation, automatically detecting motor parameters during initialization to optimize control performance.
The ENA (enable/disable) port controls the motor's state. When the internal optocoupler is off, the drive supplies current to the motor. When it's on, the drive cuts off current to each motor phase, placing the motor in a free state where it won't respond to stepper pulses. This port can also be used to restart the drive after a fault, provided the fault is cleared and a trailing edge signal is input to the ENA terminal. The level logic of the enable signal can be configured as opposite to the default.

Usage Features:
- Motor Compatibility: Designed for low resistance and low inductance hybrid stepper motors, commonly 3-phase with 3 or 6 leads.
- Control Signal Interface: Standard DM series drives use a switch interface. Compatible with pulse signal generating devices such as PLCs, MCUs, control cards, and controllers.
- Pulse Level Compatibility: Supports 3.3V-24V pulse levels without requiring external resistors.
- Power Supply Selection: Higher input voltage can increase motor torque at high speeds, while lower voltage can reduce motor heating for low-speed applications.
- Acceleration/Deceleration: Built-in S-type acceleration and deceleration. The motor accelerates to the set speed when the switch is closed and decelerates to a stop when the switch is off.
- Pulse Filtering Function: Can be enabled to smoothen input pulse commands, resulting in softer motor acceleration and deceleration. The default filtering time is 6.4ms, configurable up to 25.6ms via software.
- Motor Direction Selection: DIP SW5 controls the initial running direction (clockwise or counterclockwise) based on the initial pulse.
- Control Mode Selection: DIP SW8 allows selection between closed-loop and open-loop control modes.
- DIP Switch Configuration: DIP switches SW1-SW4 are used to set the output current, SW6-SW8 for pulse per revolution settings, SW5 for motor direction, SW6 for pulse filtering, SW7 for pulse mode, and SW8 for open/closed loop selection.
Maintenance Features:
