1.3 RS485 Bus
The RJ11 connector of RS485 intermodular connects directly to the same RS485 bus.The
RS485 line needs a terminating resistor of 22kΩ or higher. This connector can be used to
communicate with the Controller in the place of the USB connection.
1.4 Open loop/closed loop
The Controller has three different movement modes of operation. When executing a
movement, the controller will drive a stage differently when set to different modes.
The first mode(Legacy Open Loop) is a traditional Open Loop. It follows a standard
trapezoidal velocity characteristic. It bases the transition between acceleration, constant velocity
and deceleration. This is entirely theoretical and does not guarantee a set trajectory or end point.
The second mode(Special Open Loop) is also open loop, however this one does not follow
the standard trapezoidal velocity set by the user. Instead, it rounds off the velocity to an even
number of servo clocks per transition. This causes the motor to sound much cleaner than the
previous mode. However it does sacrifice accuracy.
The third mode (Closed Loop) is a traditional closed loop. The controller will constantly try
to achieve an ideal trapezoidal velocity characteristic. Like the previous mode it can guarantee
position final within the specified deadband.
