Cam control

Function
In "Cam control" operating mode, switching signals are generated dependent on an encoder
value.
The axis can be executed as:
● Linear axis
● Rotary axis with modulo function
The ET 200SP distributed I/O system determines the current actual position value of the axis
using an encoder that is connected to an encoder module, e.g. I/O module or TM Count
1x24V/TM PosInput 1 technology module. In doing so, the encoder signals are evaluated,
e.g. the pulses, which are proportional to the distance covered, are counted. The digital
outputs (cams) switch on or off depending on the actual position value. However, the output
value can be overruled by the control interface, PROFIenergy or CPU STOP.
A maximum of 16 cams can be configured for each DQ4HS module. These 16 cams can be
distributed among the 4 outputs of the module as desired.
You realize a cam control with more than 4 cam tracks with the help of several DQ4HS
modules, whereby each DQ4HS module can represent up to 4 cam tracks. All the DQ4HS
modules of this cam control unit are supplied from a single encoder source but have their
own input/output area. Each DQ4HS module has its own control/feedback interface and can
operate independent of the other DQ4HS module in the multi-track cam control unit.
The DQ4HS module can also be used in mixed operation. In mixed operation, a portion of
the outputs can be used as cam track and the rest of the outputs can be controlled directly
by the CPU.
Requirement
The cam control function can only be used in combination with an interface module that
supports module to module communication (MtM). For example, interface module
IM 155-6 PN/2 HF V4.1 or higher.
