Description
"Acknowledge START": confirm, feedback.
"Acknowledge an error": the user confirms that he has noted the error. The
device then exits the error status (errors can only be acknowledged for the
CMMO-ST if the cause has been eliminated beforehand).
In the network cable between the CMMO-ST and your computer, the
individual wires between the two RJ-45 plugs can be connected in a straight
or cross-over configuration. This is detected automatically. MDI = Medium
Dependent Interface.

Parameterisation and commissioning software
(FCT = Festo Configuration Tool)
The deviation between the setpoint position (in accordance with the
pre-calculated course of the path) and the actual position is calculated
during the execution of a positioning record. This deviation is designated a
following error. The following error can only be detected in closed-loop
operation, i.e. when positional feedback is provided by an encoder
(closed-loop).
Overview of measuring reference system
Proximity sensor used for defining the reference point.
Input/output
Observe the difference between the electrical-physical and the logical status
of an input or output.
Inputs:
– When the circuit is closed an electrical-physical 1-signal is present at the
affected input. The input is "set", the status is "HIGH".
– When the input is set in an electrical-physical manner (1-signal), all inputs
are also set as logical by default (1-signal).
An exception to this rule includes "inverted" inputs, such as the PAUSE
input (STOP/HALT). This must be set in a electrical-physical manner so
that the PAUSE function is inactive. The input is then logically 0, i.e. NOT
logically set.
This is similar for the outputs. Outputs which are typically inverted include
the error output or "Pause" output (Stopped).
Overview of drive functions
The load voltage supplies the power electronics of the motor controller and
thereby the motor. The logic voltage supplies the evaluation and control
logic of the motor controller.
