Parameters setup

3.1 Parameters P1

This series characteristics are used to set up some functions by clients self, they can be self-adjust according to clients’ different demand. They are operation functions, have no relation with fundamental characteristics of driver

3.2 Control panel operation

 As picture on left, there are 4 keys on the panel,

“SET”: press this key can enter or quite P1 setup menu

 “▲”and “▼”: “+”and “-”,to choose the function and adjust the parameters. Otherwise, “+”is the hotkey to enter trial operation function.

“ENT”: “confirmation” and “operation”, when setting parameters, press this button to enter adjustment interface and jump. Under trial operation type, press ENT to start or stop motor.

Display instruction: total 6 digital tube shows “888888”, the light most is first and the lowest

Attention: The adjustment is forbidden if the adjusted value is larger than the maximum allowed, the bottom will be no response.

3.3 How to set parameters

Example:

Demand: set internal speed (P1.1) to 1000rpm/min

Operation step as below:

1. After connecting  with  power, display “H  0”, the driver is standby, press “SET”, will display“P0。 0”
2. Press “SET”, display “P1  0”, the driver is entering P1 setting state
3.Press “▲”, until display “P1。 4”
4. Press “ENT”, display “2000”, and the first of light most is flashing
5. Press “ENT”, until the flashing is moving to the fourth position
6. Press “▼”, change into “1000”
7. Press “SET”, display “P1。 4”, the parameters had been set up and save automatic
8. Press “SET” again, display “P2  0”
9. Press “SET” again, back to standby state, display “H  0”, now, the new parameters adjustment had finished and take effect

Attention:
1. after adjustment, the driver need to connect with power again, then the new parameters will take effect   

     2. The parameters with “★” in the list can not been adjust when motor working

3. The adjustment is forbidden if the adjusted value is larger than the maximum allowed, the bottom be will no response 

Wiring Diagram

Functions

1. Speed adjustment method

This driver provide below three adjust methods for the user to choose: 

Analog voltage adjustment speed: the terminals of external potentiometer connect to the +5v terminal in signal control and COM, connect the regulator terminal to SV, not only make it possible to adjust speed by external potentiometer (10K~100K), but also can achieve speed adjust through other control unit (Such as PLC, Microcontroller, 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 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 will adjust by the duty radio liner adjustment.

The third method to adjust speed is using communication order controlling

2. Motor operate/stop control (EN)
You can control the brushless motor to run or stop by controlling the terminal “EN” and “COM” connecting. The motor will run when we connect the terminal “EN” to “COM”; when shut down, the motor will stop naturally. And the starting time will decided by the initial setup in panel, the motor running will be affected by load added 

3. Motor rotation direction control ( F/R )
You can control the motor rotation direction by controlling the terminal “F/R” and “COM” connecting. When connect terminal “F/R” to terminal “COM”, 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 controller shall be caused to damage.

4. Break the motor to stop  ( BK )
You can break the motor to stop if need. Motor can be running when the terminal “BK” not connect to “COM”, but if you connect these two terminal together, motor will stop quickly. If the overload alarm frequently, you need to add brake resistance for driver, the resistance value is not less than 100Ω, and power is not less than 100W. Attention: when install the brake resistance, the driver must be under without power and indicating light state. The brake resistance accessories is for charge

5. Speed signal output (PG) 

The speed pulse output is 0C, output 30V/10mA max. You can connect with a resistance (3K ohm ~10K ohm) between “PG” and the input power to get the speed pulse signal. The relationship of output frequency F(Hz) and speed N(rpm)is: F=N * P / 60 , P is the pole pairs of motor, Output Pulse per revolution.

6. Alarm output (ALM)
The alarm output port is 0C, output 30V/10mA max. You can connect with a resistance (3K ohm ~10K ohm) between ALARM output and the input power to get the alarm signal. When alarm, this port and the GND connecting (Low voltage), and the controller will stop working and keep in alarm status.

Working methods

The driver has three working methods by setting panel. The first is panel manual operation, press R/S to start or stop the motor, press + - to up or reduce the speed, press“ ←∣”ENTER to confirm the speed. The second is by external terminals, the motor is working with settle, digital tube display running speed. The third method is communication type.

Protection type

When the motor is running abnormally, the digital tube will display:

(1) OL   motor locked。

(2) OC   over current。

(3) HE   hall signal failure。

(4) LV   under voltage input 。

(5) HU   over voltage input。

(6) EE   IPM failure protection。

(7) OT   motor too hot

System using

Firstly, connect motor and driver lines (wounding lines, hall signal lines and power line) in strictly observe related norms and specification. It can’t to reverse the motor by change lines connection, it is completely different with asynchronous motor. The motor and driver can not work normally even damaged if lines connected wrong

You can start the trial operation after connecting motor power line, hall line and driver power lines. At first, set the control panel or terminal control, secondly set the pole pairs of brushless DC motor (wrong pole pairs will display inaccurate speed and offer wrong inner parameter ), then press the start button, enlarge the potentiometer slightly , the motor will run, if the motor do not work, or shake, or alarm, maybe the lines connection is not correct, or load is too large, please check again, until the motor running normally.
