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 bldc motor driver (user Setting)   RV—Turn Off

 

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

SW1/ Off (Factory setting) set J1 (internal) as bldc motor driver (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:

◆ 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 <bldc motor controller> or <bldc motor controller> 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

Function4:run-up time
Communication format:“y“ 0X00
Instruction:send “y“ then a hexadecimal number

Safety attention:

1、The motor and drive wiring must be connected in the power-off state. Do not connect electrical wiring under power.

2、According to the illustrated method, connect the power cord, motor winding wire and Hall signal line correctly. Please pay attention to the order of UVW three-phase must be consistent.

3、Do not disassemble the drive at random to prevent damage.

4、Do not touch all terminals on power-on state.

5、Do not drive without shell operation

6、Impact of the drive may cause damage.
