terminals of the same phase of the driver(A+,A- is one phase, B+,B- is another
phase). 57HS22 motor lead definition, Series and Parallel Connections method is

FD430 driver can only drive 2-phase hybrid step motors, which cannot drive 3-phase
and 5-phase stepping motor.

）
The method of judging whether the stepping motor is connected in series or in
parallel is correct, When the driver is not connected, directly rotate the motor shaft
by hand, If it can rotate easily and evenly, then the wiring method is correct; If the
resistance is large and uneven rotation with a certain sound, then the wiring method
is incorrect.

. Protection Functions
1
）
Short Circuit Protection / Over-current Protection
Over-current protection will be activated when continuous current exceeds the limit
current value or in case of short circuit between motor coils or between motor coil and
ground, and RED LED will turn on once within each periodic time (3 s). Reset the driver
by repowering it to make it function properly after removing above problems.
2
）
Over-voltage protection
When power supply voltage exceeds 38VDC, protection will be activated and RED
LED will turn on twice within each periodic time (3 s). Reset the driver by repowering it
to make it function properly after removing above problems.
3
）
Phase Error Protection
。
Motor power lines wrong & not connected will activate this protection. RED LED
will turn on four times within each periodic time (3 s). Reset the driver by repowering it
to make it function properly after removing above problems.
Attention
:
since there is no protection against power leads (

) reversal, it is critical
to make sure that power supply leads correctly connected to driver. Otherwise, the driver
will be damaged instantly.
