Open-loop DC drive DP3L

three-phase stepperhigh-performancehigh-voltage

Product overview
The DP3L series is a high-voltage, open‑loop pulse-type stepper motor driver designed for 200–240 VAC supply. It integrates an updated control algorithm that increases torque and speed performance by approximately 10–30% at medium and high speeds compared with the previous model. Pulse and direction inputs accept both 5 V and 24 V levels.

Key features

• Updated control algorithm delivering 10–30% higher torque at medium/high speeds versus previous model.
• Improved motor performance with reduced motor temperature rise.
• 3-digit dialing for selecting 8 current levels.
• 4-digit dialing for selecting 16 subdivision (microstep) levels.
• Automatic power‑on self‑tuning function.
• Optional automatic half‑current when stationary to reduce heat and power consumption.
• Pulse response frequency up to 200 kHz.
• Protection functions: overcurrent, overvoltage and short‑circuit protection.
• External alarm output: maximum output current 50 mA, withstand voltage 24 VDC.

Typical applications

• Slicing machines
• Garment packaging machines
• Non‑woven bag making machines
• Glove manufacturing machines
