PED+
O
In-position Signal: OC output signal, activated when actual motor position reaches to the
target. This port can sink or source MAX 20mA current at 24V. In default, the impedance
between PED+ and PED- is high impedance in normal operation and becomes low when the
target is reached. The active impedance of in-position signal can be software configurable
(see software manual).

ALM+
O
Alarm Signal: OC output signal, activated when one of the following protection is activated:
over-voltage, over current and position following error. This port can sink or source MAX
20mA current at 24V. In default, the impedance between ALM+ and ALM- is low impedance
in normal operation and becomes high when any protection is activated. The active
impedance of alarm signal is software configurable.

The power input connector is a two pin screw terminal. It has the +Vdc and GND inputs which corresponding to the
positive and negative output the power supply, respectively.

The RS232 communication connector is used to configure the programmable parameters like micro step, holding
current percentage, active edge/level of control signal, etc. A PC with at least one serial port is required. You can
copy the software either from
http://www.leadshine.com
or form Leadshine CD. See the detail in software manual.
