1. Overview

The HBS86H hybrid stepper servo drive system integrates the servo control technology into the digital stepper drive perfectly. And this product adopts an optical encoder with high speed position sampling feedback of 50 μ s, once the position deviation appears, it will be fixed immediately. This product is compatible the advantages of the stepper drive and  the servo drive, such as lower heat, less vibration, fast acceleration, and so on. This kind of servo drive also has an excellent cost performance.

5.5 Sequence Chart of Control Signals

In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram:

Remark:

PUL/DIR

1. t1: ENA must be ahead of DIR by at least 5μ s. Usually, ENA+ and ENA- are NC (not connected).
2. t2: DIR must be ahead of PUL active edge by 6μ s to ensure correct direction;
3. t3: Pulse width not less than 2.5μ s;
   1. t4: Low level width not less than 2.5μ s.

6. DIP Switch Setting

6.1 Activate Edge Setting

SW1 is used for setting the activate edge of the input signal, “off” means the activate edge is the rising edge, while “on” is the falling edge.

6.2 Running Direction Setting

SW2 is used for setting the running direction, “off” means CCW, while “on” means CW.

6.3 Micro steps Setting

The  micro  steps  setting  is  in  the following table, while SW3 、

SW4 、 SW5 、 SW6 are all on, the internal default micro steps inside is activate，this ratio can be setting through the HISU

1. Typical Connection

This drive can provide the encoder with a power supply of +5v, maximum current 80mA. It adopts a quadruplicated-frequency counting method, and the resolution ratio of the encoder multiply 4 are the pulses per rotate of the servo motor. Here is the typical connection of

10. Parameter Setting

The parameter setting method of 2HSS86H-KH drive is to use a HISU adjuster through the 232 serial communication ports, only in this way can we setting the parameters we want. There are a set of  best default parameters to the corresponding motor which are care

adjusted by our engineers, users only need refer to the following table, specific condition and set the correct parameters.

Actual value = Set value × the corresponding dimension

There are total 20 parameter configurations, use the HISU to download the configured parameters to the drive, the detail descriptions to every parameter configuration are as follows:

11. Processing Methods to Common Problems and Faults

11.1 Power on power light off

n No power input, please check the power supply circuit. The voltage is too low.

11.2 Power on red alarm light on

n Please check the motor feedback signal and if the motor is connected with the drive.

n The stepper servo drive is over voltage or under voltage. Please lower or increase the input voltage.

11.3 Red alarm light on after the motor running a small

angle

n Please check the motor phase wires if they are connected correctly， if not， please refer to the 3.4 Power Ports
