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
