3. Product description
Festo P.BE-CMMD-AS-HW-EN 1002NH 35
Limit switch
The limit switches serve to limit the range of motion for safety reasons. During homing,
one of the two limit switches can serve as reference points for positioning control.
Sample input
If a fieldbus is used for activation, a high-speed sampling input is available for time-critical
tasks for various applications (position sensing, special applications, ...).
Analogue input
The CMMD-AS motor controller has an analogue input for input levels ranging from
+10 VDC to –10 VDC. The input is a differential input (12 bit), ensuring a high degree of
protection against interference. The analogue signals are quantified and digitalised by
the analogue-digital converter at a resolution of 12 bits. These analogue signals serve to
specify setpoints (speed or torque) for the control.
Basic functions
The existing digital inputs are already allocated to the basic functions in standard
applications. The analogue input AIN0 is also available as a digital input for use of further
functions, such as the jog function, route program and synchronisation.
Mode switching allows you to switch between the following default settings:
Mode Function
Mode 0 Positioning
Mode 1 Jog function
Mode 2 Travel program
Mode 3 Synchronisation
