Description:

JKBLD300 DC brushless driver is suitable for speed regulation of three-phase DC brushless motors with power below 300W, and it can provide external potentiometer speed regulation, external analog voltage speed regulation, and PWM speed regulation of upper computer (PLC, microcontroller, etc.). At the same time the driver has a large torque start, fast start and braking, forward and reverse switching, manual and automatic speed control. It is suitable for DC brushless motors with voltage from 14V to 56V and power less than 300W.


Features:

  • Acc/Dec time setting

  • Pole-pairs selection

  • Open/closed loop control

  • Max output current P-sv setting

  • Restart

  • Alarm indication

  • Built-in RV speed setting

  • External potentiometer speed setting

  • External analog signal speed setting

SPEED Output pulse frequency corresponded with running speed. Speed can be figured out according:

N(rpm)= (F/P)x60/3

F:Output pulse frequency  P: Motor pole pairs N: Motor speed

For example: Motor has 4 pole pairs,

   F=1sec/2ms=500Hz

   N(rpm)=(500/4)x60/3=2500

ALM Motor or driver fault signal output. It is 5v in normal  situation and 0V when fault occurs

1, Q: The motor does not turn and no holding torque:

     A: ① check whether the power line is connected to the wrong voltage is too low, need to increase the voltage or correct the power line

         ② check whether the motor wiring is correct, if not correct motor wiring. Check if the motor wiring is correct, if not, correct the motor wiring.

         ③ Whether the enable signal is valid, resulting in the motor does not work.

         ④ Is the subdividing parameter correct?

         ⑤ Is the current parameter correct?


2、Q:Motor does not rotate but has holding torque:

      A: ① The phase sequence of motor wires is wrong, need to swap any two wires.

          ② Pulse signal input is wrong, need to check the pulse wiring.


3、Q: The motor torque is too small:

      A: ① Phase current setting is too small, need to set the phase current corresponding to the motor.

          ② acceleration is too fast, reduce the acceleration value

          ③ motor blocking, need to rule out mechanical problems

          ④ drive and motor mismatch, need to replace the appropriate drive


4、Q:Motor steering error:

      A: ① motor line phase sequence is wrong, need to swap any two wires

          ② motor line has a broken circuit, check and connect the right


5、Q:The alarm indicator light is on:

     A: ① Is the motor wire connected incorrectly

         ② Whether there is over-voltage and under-voltage conditions

         ③ Motor or driver is damaged


6、Q:Motor acceleration blocking:

     A: ① short acceleration time

         ② motor torque is too small

         ③ Low voltage or current
