5. Function and Usage

Speed adjust method

This driver provides the user below three-speed control method:

Inner potentiometer speed adjustment: Rotate the potentiometer on the driver panel

counterclockwise, the rotate speed decrease, rotate the potentiometer on the driver panel

clockwise, the rotate speed becomes higher. Please make sure the potentiometer is set in the

minimum state when you use external input mode to adjust the speed.

External input adjustment: Connect the terminals of the external potentiometer to the GND and

+6.25v terminal, connect the regulator terminal to SV, then you can adjust the speed by using an

external potentiometer. It also can achieve speed adjust through other control units (Such as PLC,

SCM, etc) input analog voltage to SV. The acceptance of SV is DC 0V~+5V, and the corresponding

motor rotate speed is 0 to rated speed.

You also can use the external digital signal to adjust speed: apply PWM with 5V amplitude and

1KHz~2KHz Frequency between SV and GND to adjust the speed. the motor rotate speed is

adjusted by the duty radio liner adjustment. At this time, by adjusting the R-SV potentiometer,

SV digital signal amplitude can be 0~1.0 ratio attenuation processing. Generally, adjust R-SV to

1.0, SV input digital signal without attenuation processing.

Motor operate/stop control (EN)

You can control the brushless motor to run or stop by controlling the terminal “EN” and “GND”

BLD-AC750S Brushless Driver

connecting. The motor will be running when we connect the terminal “EN” to “GND”; when

shut down, the motor will stop naturally, and the stopping time will be decided by the inertia

and load adding on the motor.

Motor rotation direction control ( F/R )

You can control the motor rotation direction by controlling the terminal “F/R” and “GND”

connecting. When connecting terminal “F/R” to terminal “GND”, the motor will run at CCW

(view from motor output side), and when shut down, the motor will run at another direction.

Attention: If you need to change the motor rotation direction, please stop the motor at

first, otherwise the driver shall be caused to damage.

Brake the motor to stop ( BK )

You can break the motor to stop if need. The motor will run when the terminal “

K” not

connects

“GND”, but if you connect these two terminals, the motor will stop quickly. And the

motor stopping time will be decided by inertia and load adding on the motor.

Attention: If you are not necessary to stop the motor quickly, please DO NOT use this function,

cause it has some electrical and mechanical impact on the motor and driver.

Speed signal output(PG)

The speed pulse output port is 0C, output 30V/10mA max. You can connect with a resistance

(3K ohm ~10K ohm) between signal and input power to get the pulse signal, this port will output

serial pulses which has fixed extent ( it is 50uS). This output pulse from every rotation of the

motor is 3 x N, “N” means the total pole number of the magnet. For example, 2 pair of poles,

means 4 poles motor, 12 pulses per turn, when the motor speed is 500rpm, the pulses out

from the PG is 6000.

Alarm output (ALM)

The alarm output port is 0C, output 30V/10mA max. You can connect a resistance (3K ohm

~10K ohm) with the input power to get the alarm signal. When alarm, this port is connecting

the

GND (Low voltage), and the driver will stop working and keep in alarm status.

Drive failure

Over-voltage or over-current will lead the driver to a protection status, the driver will

automatically stop working, the motor stop and blue light are flashing. As long as you enable

BLD-AC750S Brushless Driver

terminals to reset (EN and GND disconnected) or power Off, the driver will disarm the alarm.

Please check the motor wiring once this failure occurred.

6.1 Parameter Setting Sequence

Please insure that the motor is under the stop situation when set the parameter. That is, in

panel mode, the motor is in the stop state or, the motor is enabled to disconnect in external

port mode,

1. In standby condition, press “ENTER” to call out the system parameters, press “ENTER” again, it

will call out the parameter value.

2. Press “△” or “▽” to the parameter number you want. Press “SET” to return to standby mode if

there is no need to change value.

3. Press “ENTER” to show the parameter setting value. Press “SET” to return to standby mode if

there is no need to change value.

4. Press “△” or “▽” to the value demanded.

5. Press “ENTER” to save the changes and press “SET” to return to standby mode.

Note: At setting mode, it will return to speed display interface if there is no press within one minute.

6.2 Working mode

Motor works at two modes. One is the panel mode, another is terminal control. The motor runs

as the setting, display shows the speed of motor. Under the panel mode, Press “SET” to start/stop

the motor, long press “△”or

“

to acceleration or deceleration speed, press “ENT” to insure

and know the running speed.

Mark 2: The system working mode is divided into "speed mode" and "control mode". The

speed mode is defined in P000, and the control mode is defined in P013.

7. System usage

Connect on the wires of the motor and driver (motor winding wires, Hall sensor, and power supply)

strictly as request. It can not achieve the CW and CCW through changing the wires connection like

the asynchronous motor. The motor will run abnormality with the wrong wires connection, like

brushless motor will shake much or heat quickly (the temperature will up to 80 degrees in seconds

to 2 min.), and will damage the motor and driver.

Please run the motor while connecting the power supply, Hall wires and drive power supply. Firstly

set the potentiometer to the minimum, press the start switch, increase the motor potentiometer

a little, the motor should run. If the motor does not run or shaking, maybe did the wrong wires

connection, please recheck the brushless motor wires till the motor running normally.

8. Communication Mode

This communication model is used standard Mod bus protocol, implement national standards GB/T

19582.1 - 2008. It is using RS485 two-wire serial link communication, Physical interface uses two

3.81mm spacing 3 core Phoenix terminals, the serial connection is very convenient. The transmission

mode is RTU, the testing mode is CRC, CRC start word is FFFFH. Data mode is 8-bit asynchronous

serial, 2 stops bit, without an invalid bit, Supports multiple communication rates (see the table of

parameters)

Parameters function supporting: 03H is for multi-register read, 06H is for single register write
