Festo P.BE-CMMS-AS-HW-EN en 0708NH 25
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 Field bus 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 motor controller CMMS-AS has an analogue input for input levels in the range of +10 V
to -10 V. The input is designed as a difference input (12 bit) to ensure 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 spec-
ify setpoints (speed or torque) for the control.
Basic functions
The existing digital inputs are already allocated to the basic functions in standard applica-
tions. The analogue input AIN0 is also available as a digital input for use of further func-
tions such as the jog function, route program and synchronisation.
MODE switching allows you to switch between the following default settings:
