Fine Tuning
Leadshine already loads default current-loop parameters and position-loop parameters. Those
default parameter values have been optimized. They should be good enough for most industrial
applications, and there is no need to tune them. However, if you want to fine tune the IES for best
performance for your applications, Leadshine also offers tuning software, ProTuner, which allows you
to adjust those current-loop and position-loop parameters (see software manual).
Protection Functions
To improve reliability, the HBS incorporates some built-in protection functions. The HBS uses one red
LED to indicate the protection type. The periodic time of red is 4 s (seconds), and the blinking times
of red LED indicates what protection has been activated. Because only one protection can be
displayed by red LED, so the drive will decide what error to display according to their priorities. See
the following protection Indications table for displaying priorities.

Over-current Protection
Over-current protection will be activated when continuous current exceeds the limit or in case of
short circuit between motor coils or between motor coil and ground, and RED LED will blink once
within each periodic time.
Over-voltage Protection
When power supply voltage exceeds the limits, protection will be activated and red LED will blink
twice within each periodic time.
!
Caution
When above protections are active, the motor shaft will be free or the LED will
blink. Reset the drive by repowering it to make it function properly after removing
above problems. Since there is no protection against power leads (

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