JKBLD750 Brushless DC Motor Driver

The JKBLD750 BLDC motor drive is a high performance, cost-effective 3phase BLDC motor drive, which can provide power output Max 750VA.The design is based on advanced DSP technology and feature high torque, low noise, low vibration, PID speed loop, PID current loop, over current protection, over load protection and a combined use of manual speed adjustment and automatic speed adjustment.

Note①: Potentiometer/10KΩ or analog signal DC 0V~+5V (Change

internal switch J1/DC0-10V).Turn off the internal potentiometer  RV

when using an external potentiometer to adjust the motor speed.

Note②:High level/5V (5mA) 

●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  (user Setting)   RV—Turn Off

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

 SW1/ Off (Factory setting) set J1 (internal) as  (user Setting)   RV—Turn Off

● Motor Speed Adjusted By Pulse Rate Input:

Pulse rate: 0K—3KHZ Speed linear modulation  

Pulse amplitude: 5V   Pulse duty ratio: 50%

SW1/ On (User setting)      RV—Turn 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—Pulse output frequency

P—Pole 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: Take care of the sequence of U,V,W

Motor Parameter set by ICAN BLDD-01 (Optional) :

●RS232 Communication Interface CP-in

The BLDD48-45A  BLDC motor drive support RS232 communication Protocol to set motor run-up time, etc. When choose ICAN BLDD-01 as host controller, the operating process and instruction as below:

●ICAN BLDD-01 Motor Setting Panel Operating Process:

Connect to CP-in (BLDD48-45A)

SW1/ Off (Factory setting)   RV—Turn Off

BLDD-01 Parameter Setting Table:

● BLDD-01 Panel Setting Process:

1. Turn on the power supply, press <Set> to stop the motor

2. Press <▲> or <▼> to choose the mode you need  (Press Esc  return and motor running)

3. Press <Set> enter into parameter mode (Press Esc return and motor running)

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

5. Press <Set> to reserve, parameter stop to flash. Press <Esc> return and motor running.

Panel Protection Mode:

When the system running, panel nixie light shows Err×

Err0 represents Over-voltage or Over-temperature protection

Err1 represents Over-current protection

Err2 represents Hall sensor error protection

●Motor Parameter set by other host controller:
