Problems Suggestions
Motor does not rotate.
Check whether the ATYPE of the controller is correct;
Check whether the pulse send mode matches the input
pulse mode of the drive;
Check whether the motor already reached hardware or
software position limit, resulting in ALM signal comes.
Check whether pulse count is normal in ZDEVELOP.
The controller works normally,
pulses is sent out normally,
motor still does not rotate.
Check whether connection between drive and motor is
correct and whether connection between the drive and the
controller is correct.
Check whether the drive works properly and there is no
alarm.
Motor can rotate, but it doesn’t
work normally.
Check whether deceleration and speed exceed the device
limit;
Check whether pulse frequency output exceed the
receiving limit of the drive;
Check whether connection between controller and drive
are correct and whether anti-interference measures are
well done;
Check whether current limiting resistance used in the
photoelectric isolation circuit of pulse and direction signal
output is too large and the working current is too small.
Motor is under control, but it
may oscillate or overturn
sometimes.
Check whether the drive parameters setting is correct.
Check whether acceleration or deceleration period and
motion speed were set properly in Software.
Motor is under control, but
homing position is inaccurate.
Check whether the origin signal switch works normally;
Check whether the origin signal is disturbed.
The position limit signal is
invalid.
Check whether the position limit sensor works normally;
Check whether t
he signal of the limit sensor is disturbed;
The expansion module cannot
be connected, and alarm light
of the expansion module is on.
Check whether there is a 120Ω resistor at both ends;
Check whether multi expansion modules use the same ID.
No signal comes to the input.
Check whether the IO is supplied normally;
Check whether the input signal level matches the input
channel.
Check whether the input number matches the ID of the IO
board.
The output does not work.
Check whether the IO is supplied normally;
The IO also needs supply.
Check whether the output number matches the ID of the
