1 Overview
1.1 Product Description
The servo stepper drive system combines the advantages of open-loop stepper and
servo control, and is particularly suitable for the upgrade of open-loop stepper drive
control and the cost reduction of traditional servo control.
1.2 Feature
l Digital PI current loop, low noise.
l Three operating modes:
- Self-operating mode: The motor can be triggered by a pulse signal. When
the pulse signal optocoupler is turned on, the motor starts self-run
according to the parameter setting of PA-45~PA-53; when it is turned off,
the motor stops self-running.
- Open loop mode: for testing and emergency use. The motor temperature
rise is higher.
- Position mode: This mode is the default mode of the drive and is suitable for
most occasions. When the driver works in this mode, the motor does not
lose step, the temperature is low, and the high and low speed performance
are better than the open loop mode.
l The microstep setting can be any number between 400-60000.
l Protection functions such as overcurrent, phase error, overvoltage and position
deviation error.
l 6 digital LED display, which can easily set parameters and monitor motor
running status.
l Pulse command averaging filter, the filter can turn the curve without
acceleration and deceleration into a trapezoidal acceleration/deceleration curve,
which greatly smoothes the motion. The trapezoidal acceleration/deceleration
curve is filtered to become a smoother S-shaped acceleration/deceleration
curve. Especially suitable for point-to-point sports occasions.
l Three types of pulse command: pulse + direction, double pulse(CW/CCW) and
quadrature input.
1.3 Application field
Mainly used in robots, industrial robot arms, engraving machines, wire stripping
machines, marking machines, cutting machines, plotters, CNC machine tools, automatic
assembly equipment and pattern machines.

BHSS-1000W-PARA (Parameter) belongs to easy servo (servo-stepper) drives. With new generation
of 32-bit DSP motor control technology, which completely overcomes the problem of lost step of
open-loop stepping motor, BHSS-1000W-PARA greatly improves the high and low speed performance
and torque utilization rate of stepping motor, and effectively reduces motor heat.

Install the drive with the upright side installation to create a strong air convection on
the surface of the heat sink; if necessary, install a fan near the drive to force heat
dissipation to ensure that the drive works within a reliable operating temperature range
(The reliable operating temperature of the drive is usually within 60 ° C and the motor
operating temperature is within 80 ° C).

7 Common faults and handling
Caution：
l The drive and motor must be powered off for at least 5 minutes before
touching the drive and motor to prevent electric shock and burns.
l After the drive fault alarm, it must be eliminated according to the alarm code
before it can be put into use again.
7.1Troubleshooting
Does the LED display an error
code?
Is the supply voltage within the voltage range
required by the drive?
Is the power input connected?
Is the connecon loose?
Is the connecng part loose, disconnected,
broken, or shorted?
Is the wiring correct?
Is the control
