Start-Up

8.1 Configuring the System
Before putting the IP 266 into operation, you must check to make sure that you
are using the right interface module and that the peripheral elements have been
assigned the correct parameters.
These peripheral elements include:
• the emergency limit switches
• the power section on the IP 266's analog output
• the hardware limit switches
• the drive system mechanics
• the incremental position encoder
• the programmer.
8.1.1 IP 266 Limit Switches
In order to limit the positioning range, you must fit limit switches which ensure
that the drive will be moved only within its mechanical limitations.
The limit switches must be connected and tested before powering up the IP 266
and the power section.
As regards the IP 266, you must differentiate between software limit switches,
hardware limit switches and emergency limit switches.
• Software limit switches
You define the locations of the software limit switches in the machine data.
These switches are activated when a reference point is set.
• Hardware limit switches
Hardware limit switches are switches which are connected to the IP 266 via
connecting leads. They are connected to the terminals on the terminal block,
and are used to limit the path of travel.
