Product Description

BLD-300B
Brushless DC Motor Drive
Description
The BLD-300B is a high performance, cost-effective 3 phase BLDC motor drive
which can provide power output 300VA max. 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. The BLD-300B also
support RS232 communication Protocol to set motor run-up time, etc.

Speed Adjustment Instruction:                                                                  Motor Speed Quick Response Setting:

A. Motor speed adjusted by the internal potentiometer RV                         OP/CL Connected (user setting): 
B. Motor speed adjusted by the external potentiometer                            PID Closed loop-Motor quick response
C. Motor speed adjusted by analog signal  0V~+5V input                         OP/CL Disconnected (factory setting):
D. Motor speed adjusted by analog signal  0V~+10V input                        NO PID Closed loop-Motor normal response
E. Motor speed adjusted by PWM input:                                       Lead Wire Connection:
Pulse duty ratio 10%-90% / Speed linear modulation                           Take care of the sequence of U,V,W
