Output Signal Wiring
The HBS drives offers ALM (alarm) signal to indicate the error status. The HBS86 has the in-position
(Pend+ / Pend-) to indicate the achievements of the target position. That is, the motor have been in
the position you want it to be. These signals are OC (Open Collector) output and can sink or source
50mA current.

Wiring Notes
l
In order to improve anti-interference performance of the drive, it is recommended to use twisted
pair shield cable.
l
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.
l
If a power supply serves several drives, separately connecting the drives is recommended instead
of daisy-chaining.
l
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.
