Wiring Notes
In order to improve anti-interference performance of the drive, it is recommended to use twisted pair shield
cable.
To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should not be tied up
together. It is better to separate them by at least 10 cm, otherwise the disturbing signals generated by motor
will easily disturb pulse direction signals, causing motor position error, system instability and other failures.
If a power supply serves several drives, separately connecting the drives is recommended instead of
daisy-chaining.
It is prohibited to pull and plug power connector while the drive is powered ON, because there is high current
flowing through motor coils (even when motor is at standstill). Pulling or plugging power connector with power
on will cause extremely high back-EMF voltage surge, which may damage the drive.
4.2 Sequence Chart of Control Signals
In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as
following diagram:
