control
For controlling a single 5645, use RS-232 communications and
install cable as described in section 2.5.3.1 “J3 Serial Port -
RS-232 Connection.”
For controlling multiple 5645s, use RS-422 or RS-485
communications, which permit a single PC to host from 1 to 31
5645s (each requiring a unique switch selectable address). For
detailed information on setup refer to section 2.5.3.2 “Serial Port
- RS-422 or RS-485 Connection.”
Digital I/O
Control input - One dedicated input to enable the controller.
Connecting this input to I/O Return enables the 5645.
Control output - An open collector (NPN) dedicated output
showing controller fault status. This output turns off to indicate a
fault. Maximum current sinking capability is 50 milliamperes
and maximum off voltage is 12 volts.
General inputs - 16 inputs to support logic type interfaces. The
input circuitry is intended to be operated with open collector type
circuitry. These inputs can be polled under software control. Six
of the 16 inputs can be pre-defined for specific functions: LIMIT
+/-, START/STOP, JOG +/- and mechanical HOME SWITCH.
General outputs - 12 open collector discrete outputs under
software control. Each output can sink a maximum of 50
milliamperes. Maximum off voltage is 12 volts. One of the 12
outputs can be pre-defined for MOTOR MOVING status.
Encoder I/O - The external encoder I/O port permits interfacing
to quadrature type encoder signals for applications such as
electronic gearing. This input can also be configured by software
as a step and direction input.
Note: Factory default is for quadrature encoder inputs.
Step/Dir Out - The Step/Dir output permits controlling external
devices so they can follow step and direction from the 5645.
This output signal is present as long as the 5645 is enabled and
executing any motion profile.
