The detailed information
Description
The BLD-120 is a high performance, cost-effective 3 phase BLDC motor drive
which can provide power output 125VA 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-200 also support
PWM external input and other speed adjustment methods.

Speed Adjustment Instruction:
A£®Motor speed adjusted by the internal potentiometer RV
B£®Motor speed adjusted by the external potentiometer
C£®Motor speed adjusted by External analog voltage input
D£®Motor speed adjusted by PWM input: Pulse duty ratio 10%-90% / Speed linear modulation
Pulse rate: 1K-10K/ pulse amplitude 5V
Peak Power Setting
To protect the motor, set the arrow number as the same as the motor nominated power. Whenever overload occurs the drive will turn out to be the protection mode. |
