JKBLD750 Nema34 / Nema 86 Motor Driver Three Phase 750W 48VDC
25A-45A
JKBLD750 brushless dc driver is suit the following three-phase sine
wave power and 48V DC 750W brushless dc motor speed regulation, can
provide an external potentiometer control, external analog voltage
control, PC (such as PLC, SCM) PWM speed regulation, and other
functions. At the same time the drive have large starting torque,
quick start and brake, and positive & negative switching,
combination of manual and automatic control.
Description:
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.

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
(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
