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
