Speed Adjustment Instruction:


Motor Speed Adjusted By The Internal Potentiometer RV:

SW1/ Off (Factory setting)   


Motor Speed Adjusted By Analog DC 0V~+5V Input:

 SW1/ Off (Factory setting) set J1 (internal) as 2.png  (user Setting)   RV¡ªTurn Off


Motor Speed Adjusted By Analog DC 0V~+10V Input:

SW1/ Off (Factory setting) set J1 (internal) as  3.png (user Setting)   RV¡ªTurn Off


Motor Speed Adjusted By Pulse Rate Input:

Pulse rate: 0K¡ª3KHZ Speed linear modulation  

Pulse amplitude: 5V   Pulse duty ratio: 50%

SW1/ On (User setting)      RV¡ªTurn Off

  J7 (Internal)/ Switch on with the jumper cap on J1 (User setting)   


Motor Speed Quick Response Setting:

SW2/ On ( User setting): PID closed loop--quick speed response

SW2/Off (Factory setting): Open loop--Normal speed response


Motor Speed Signal Output:

Connecting SPEED and COM to get pulse output F=N*P/60

F¡ªPulse output frequency

P¡ªPole number of BLDC motor


Drive Alarm Output:

When drive alarm, it will break over with the port of COM and be low

level. The drive stop to work and alarm light run.


Lead Wire Connection:

BLDD-01 Panel Setting Process:

1. Turn on the power supply, pressto stop the motor

2. Press <¡ø> or <¨‹> to choose the mode you need  (Press Esc  return and motor running)

3. Pressenter into parameter mode (Press Esc return and motor running)

4. Press < > or < > to change the parameter (flashing)

5. Pressto reserve, parameter stop to flash. Pressreturn and motor running.


Panel Protection Mode:

When the system running, panel nixie light shows Err¡Á

Err0 represents Over-voltage or Over-temperature protection

Err1 represents Over-current protection

Err2 represents Hall sensor error protection
