Product description:
The HBS series offers an alternative for applications requiring high performance and high reliability when the servo was the only choice, while it remains cost-effective. The system includes a 2-phase stepper motor combined with a fully digital, high performance drive and an internal encoder which is used to close the position, velocity and current loops in real time, just like servo systems. It combines the best of servo and stepper motor technologies, and delivers unique capabilities and enhancements over both, while at a fraction of the cost of a servo system.
Features:
- Closed-loop, eliminates loss of synchronization
- Broader operating range – higher torque and higher speed
- Reduced motor heating and more efficient
- Smooth motion and super-low motor noise
- Do not need a high torque margin
- No tuning and always stable
- Fast response, no delay and almost no settle time
- High torque at starting and low speed, high stiffness at standstill
- Lower cost

PUL+
|
I
|
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (software configurable, see hybrid servo software operational manual for more detail); In double pulse mode (software configurable), this input represents clockwise (CW) pulse, active both at high level and low level. 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. For reliable response, pulse width should be longer than 10µs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signal.

DIR+
|
I
|
Direction signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation. In double-pulse mode (software configurable), this signal is counter-clock (CCW) pulse, active both at high level and low level. For reliable motion response, DIR signal should be ahead of PUL signal by 5µs at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that rotation direction is also related to motor-driver wiring match. Exchanging the connection of two wires for a coil to the driver will reverse motion direction. The direction signal’s polarity is software configurable.

Enable signal: This signal is used for enabling/disabling the driver. In default, low level (NPN control signal) for enabling the driver and high level for disabling the driver. Usually left UNCONNECTED (ENABLED). Please note that PNP and differential control signals are on the contrary, namely Low level for enabling. The active level of ENA signal is software configurable.

In-position signal: OC output signal, active when the difference between the actual position and the command position is zero. This port can sink or source 20mA current at 24V. The resistance between Pend+ and Pend- is active at high impedance.

Alarm signal: OC output signal, active when one of the following protection is activated: over-voltage, over current and position following error. This port can sink or source 20mA current at 24V. In default, the resistance between ALM+ and ALM- is low impedance in normal operation and become high when ES-D1008 goes into error. The active level of alarm signal is software configurable. See Hybrid servo software operational manual for more detail.
