Descriptions

LM-HSD57 is one of the models in Jkongmotor series easy servo drives which can take 20-80 VDC operating voltage and output 0.1 -10A continuous load-based current. It is capable of driving NEMA 17, 23, 24 and 34 easy servo motors (stepper motors with encoders) with the position loop closed in real time. Based on latest DSP technology and adopting Novo's advanced control algorithm, LM-HSD57 easy servo drive applies servo control on easy servo motors. When adopted with an easy servo motor, it combines features of both open loop steppers & brushless servo systems, and offers many unique advances features for excellent motion control system performance. When an LM-HSD57 easy servo drive is implemented with a novo SC series easy servo motor, there is No Configuration Needed for almost all applications. The output resolution from LM-HSD57 with the output resolution defaulted to output resolution of 2,000 pulses per resolution (equal to 10 microstep in 2-phase stepper systems). Via DIP switches, a user can also easily change the output resolution to one of 15 output resolutions 400 to 51,200 (equal to 2-256 microstep in 2-phase stepper systems). With novo configuration software, ProTuner, an

advanced user can also set custom settings of resolution, current & position loop parameters, idle current

percentage, etc.

Nema 34 Close Loop Stepper Motor Digital Stepper Driver Manual:



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
