0-5A 2-Phase closed loop Stepper Drive for Adjustable Current Control

0-5A 2-Phase closed loop Stepper Drive with Adjustable Current

The 0-5A 2-Phase closed loop Stepper Drive 2HSS57 sets output current in the 0-5 A range from a 24-60 VDC supply and implements full closed loop control, using encoder feedback to regulate the current, speed, and position loops. An adjustable current window lets the drive match a range of motor sizes rather than a single fixed rating. Lyenwsin supplies this drive for compact CNC equipment, robotics, and laboratory automation.

Current Flexibility and Feedback

Because peak phase current is adjustable in the 0-5 A band, the same drive can be tuned to smaller and larger NEMA23-class motors within its power budget. The closed loop then trims actual current to the load, so the axis draws only what it needs. This lowers standstill heating and keeps the motor and cabinet cooler in duty cycles with long idle phases.

Signal-Level Compatibility

Command and status signals operate at 5-24 V, which aligns with the logic levels commonly found on PLC and controller outputs. This simplifies wiring and reduces the need for external level shifting in mixed-voltage cabinets.

Operation and Command

The drive accepts pulse/direction step commands, making it a drop-in positioning stage for established controllers. With closed loop position holding, it tolerates load transients without converting them into accumulated positional error.

Key Specifications

• Phase count: 2-phase
• Output current: 0-5 A (adjustable)
• Supply voltage: 24-60 VDC
• Signal voltage: 5-24 V
• Control mode: Pulse/Dir
• Feedback: full closed loop control

Typical Applications

This drive is suited to compact CNC equipment, robotics, packaging and printing machinery, textile and food processing lines, industrial automation, and automated handling mechanisms where adjustable current and clean signal-level handling simplify integration.

Selection Considerations

Set the current trim to the motor’s rated phase current before first run, then verify standstill temperature in the final cabinet layout. The 5-24 V signal compatibility removes most interface adapters, but confirm the controller output levels. Lyenwsin’s support team can assist with setting the current range for your motor.
