Shenzhen ECON Technology Co.,Ltd | Updated: May 10, 2016

Stepper common problem Summary


Dear Customer,


When you use ECON stepper motor,stepper drive,and easy servo,meet problems,kindly get solutions from below information.If can not get answer from here,consult our technical engineer.


One. Motor does not rotate


Reason 1,power indicator light(green) is off

Solution:check power supply circuit,make sure that the L/N polarity of power is correct,power cable connecting is fixed


Reason 2,subdivision setting is wrong

Solution:adjust subdivision setting


Reason 3,current setting is wrong

Solution:adjust current setting


Reason 4,motor release signal setting is wrong

Solution:check MF input


Reason 5,control signal drive capability is too weak or frequency is too high

Solution:improve PU signal range or lower pulse input frequency



Two.Motor rotating direction is wrong


Reason,motor wiring is wrong

Solution:2 phase motor,exchange any phase wiring(like exchange A+/A- wiring);3

phase motor,exchange any two phase wiring(like exchange U/V wiring)


Three.Motor stalling/noise/shake


Reason 1,Motor problem

Solution:change motor


Reason 2,The torque of motor is small

Solution:Replace with big torque motor


Reason 3,Motor axis and load is not coaxiality

Solution:Adjust motor and load connecting respectively location to coaxiality


Reason 4,Motor wiring is wrong

Solution:check motor wiring


Reason 5,Motor current setting does not match with drive setting

Solution:adjust drive current setting to motor rated current


Reason 6,Subdivision setting is wrong

Solution: adjust subdivision setting to correct value(generally,low setting will lead to high speed)


Reason 7,Motor operating speed is in resonance point range

Solution:Adjust motor speed to avoid physical resonance


Reason 8,Acceleration time is too short

Solution: extend accelerating time



Four.Location is inaccurate


Reason 1,Subdivision setting is wrong

Solution:adjust subdivision setting


Reason 2,Low current setting lead to step losing

Solution:adjust current setting


Reason 3,Motor and load connection is loose

Solution:check motor and load connecting,like fasten coupling


Reason 4,Signal get interference

Solution:eliminate interference,like add shield to signal input
