Stepper motor driver DP3CL

Overview
The DP3CL series open-loop bus-type stepper driver is CiA402 compliant and integrates EtherCAT communication (COE), supporting up to 32 axes. With a new-generation control algorithm and optimized bus communication, it achieves communication cycles down to 1 ms for 32 axes and enables motor speeds up to 2000 rpm depending on motor and system configuration. It is designed for multi-axis industrial applications such as electronics assembly and laser equipment.

Key features

• New-generation control algorithm: smoother motor motion and reduced motor temperature rise under typical loads.
• High-speed capability: EtherCAT and control tuning support motor speeds up to 2000 rpm (system dependent).
• Integrated EtherCAT bus (COE): standard EtherCAT master compatibility for fast, deterministic communication.
• High axis capacity: supports up to 32 axes with communication cycles down to 1 ms (for 32 axes at fastest setting).
• Simplified wiring: network cable replaces traditional pulse/direction lines; driver includes power and encoder connections to reduce cable routing and maintenance.
• Improved EMI and reliability: low bus load and point-to-point physical layer help suppress interference and stabilize system performance.

Applications

• Electronics manufacturing and assembly
• Laser processing and laser equipment
• Wire stripping and harness processing machines
• Marking and labeling machines
• Drawing machines and other multi-axis automation systems
