·
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.
7. RS232 Communication Connections
The RS232 communication only use Transmit,
Receive and ground signals. Connect them to the
serial port accordingly. The right drawing shows
the RS232 communication cable with a 9-pin
D-Shell female connector.
