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:

◆ ICAN BLDD-01 Motor Setting Panel Operating Process:

Connect to CP-in (BLDD48-45A)

SW1/ Off (Factory setting)   RV—Turn Off

BLDD-01 Parameter Setting Table:

◆ BLDD-01 Panel Setting Process:

1. Turn on the power supply, press to stop the motor

2. Press <▲> or <▼> to choose the mode you need  (Press Esc  return and motor running)

3. Press enter into parameter mode (Press Esc return and motor running)

4. Press <> or <> to change the parameter (flashing)

5. Press to reserve, parameter stop to flash. Press 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

◆ Motor Parameter set by other host controller:

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.

FAQS：

1. How can get it started as soon as possible when you first use the drive?

After you correctly connect the power cord, the motor line, the Hall line, the external potentiometer slowly accelerates. After the motor is turned correctly, you can test the enable, direction and other functions. If you are unfamiliar with the product, the initial use should be done after the test. And then it can be installed to the actual use.

2. What will come about if power supply is reverse?

It will immediately burn the drive.

3. What is the maximum of the upper control signal voltage ?

The maximum voltage of the speed regulation signal is 5V. Exceeding this voltage will cause the drive to burn.

4. After the driver has been working for a long time, the shell is hot. Is it normal?

Yes, it is. At room temperature, after long working hours, it is up to 90 degrees. And it will not affect the performance.

5. The power indicator is light, but the motor does not turn and shift, what is the reason?

There may be a mistake in the phase line and the Hall line. Please re-energize the wiring according to the motor manual.

6. Can my motor speed transferred to 6000 with this drive?

The maximum speed of the brushless motor is determined by the parameters of the motor itself. The drive can control the motor speed from 0 to the highest speed.

7. I already have a motor and how to install this drive after wiring?

You must first determine the motor phase and the definition of the Hall line, and then you can connect it with wires. If you are not sure, you need to ask the motor manufacturers. Incorrect wiring can cause damage to the drive.

8. Can I add some features on this drive or do new product development?

Yes, please contact us.
