The movement speed of the device depends on device status and various speed settings. If the device has not
been initialized by the
home
command or by moving towards the home end of the device, movement speed will be
constrained to fail-safe values. The home status of the device can be determined by reading
the
limit.home.triggered
setting.
Movement speed of the device is specified below:
move vel
The device will move at the specified speed regardless of home status.
Knob movement in Velocity Mode
The device will move at the specified speed regardless of home status.
The speed is specified by the
knob.speedprofile
and
knob.maxspeed
settings.
Other movement commands - when the device has not been homed
The device will move at the slower of the
maxspeed
and
limit.approach.maxspeed
settings.
Other movement commands - when the device has been homed
The device will move at the speed specified by the
maxspeed
setting.
I/O Usage and Examples
The X-MCC features a range of flexible input and output options that can be easily examined and controlled from
user software. The input and output capabilities of the X-MCC can also be used with
triggers
to perform actions
based on the current value of the I/O channel.
To minimize the number of power supplies needed, the on-board +5 V and GND connections can be used as non-
isolated power supplies for I/O circuitry as long as the current draw remains below 200 mA.
Digital Inputs
The digital inputs on the X-MCC are fully opto-isolated and bi-directional, giving added flexibility when interfacing to
external equipment. The two examples below demonstrate how the common line can be connected to a power rail
or to ground, depending on the application.
Each digital input contains an internal current limiting resistor of 442 ohms. While this value is suitable for driving
the inputs with 5 V (as shown in the circuit above), higher voltages will require the addition of a series resistor. A list
of recommended values for the external resistor and example circuit are shown below.
