Shared Specifications

Hybrid Stepper Servo Control

The HS86 uses a servo-like control principle while combining the characteristics of open-loop stepper and servo systems. According to the product documentation, this control approach is designed to improve stepper system performance, reduce motor heating and low-speed vibration, and provide fast start-stop response with low-vibration stopping.

The driver also supports automatic current reduction when the motor is stationary.

High-Resolution Microstep Control

The HS86 supports configurable microstep settings from 200 to 40,000 and a pulse response frequency of up to 200kHz. This provides flexible pulse-based motion control for systems requiring different microstep configurations and higher pulse input frequencies.

Control Signal Interface

The HS86 provides differential control inputs for pulse, direction, and enable functions.

• PLS: Pulse control input

• DIR: Direction control input

• ENA: Enable control input

The PLS input supports +5V to +24V signals, with a pulse width requirement greater than 2μs for reliable response. The DIR input also supports +5V to +24V signals, while ENA is used to enable or disable motor operation.

Position and Alarm Outputs

The HS86 provides PEND and ALM output interfaces for system status monitoring.

PEND provides a position-in-place output when the motor reaches the commanded position.

ALM provides an alarm output when overcurrent, overvoltage, undervoltage, or position error conditions occur. Both outputs support a maximum drive current of 50mA.

Encoder Interface

The HS86 includes an encoder interface for A/B phase feedback and provides a 5V encoder power supply.

• PA+ / PA-: Encoder A-phase input

• PB+ / PB-: Encoder B-phase input

• VCC: Encoder 5V power supply

• EGND: Encoder power ground

Power and Motor Connections

The HS86 provides dedicated power and motor phase connections. The strong-current interface documentation specifies AC20–80V input or DC30–110V input, with dedicated A+ / A- and B+ / B- terminals for the two motor phases.

RS232 Serial Communication

The HS86 uses a PH2.0-7P connector for serial communication. A dedicated serial cable and USB-to-TTL conversion interface can be used to connect the driver to a PC for parameter configuration.

Through the PC software, users can configure parameters such as motor current, microstep resolution, and operating mode. The source documentation specifies that the serial connector must not be connected or disconnected while powered.

Protection Functions

The HS86 provides protection and alarm functions for common operating faults, including:

• Overcurrent protection

• Overvoltage protection

• Undervoltage protection

• Position error alarm

These functions provide additional monitoring for hybrid stepper motion control systems.

Environmental Conditions

The HS86 supports natural cooling or fan cooling and is specified for an operating temperature of 0–50°C and relative humidity of 40–90% RH.

The installation environment should avoid excessive dust, oil mist, corrosive gases, strong vibration, combustible gases, and conductive dust.

Typical Applications

The HS86 is designed for motion control systems using hybrid stepper motors where closed-loop-style control characteristics, encoder feedback, and flexible digital parameter configuration are required.

Typical applications include:

• Industrial automation equipment

• CNC and positioning systems

• Linear motion equipment

• Automated machinery

• Precision positioning systems

• OEM motion control equipment
