Start-Up
8.4 Executing the Start-Up Test
The drive must be within the permissible traversing range before the IP 266 can
be tested together with the drive. This range is defined by the two hardware limit
switches.
C A U T I O N :
All limit switches must be correctly installed before executing the start-up test,
i. e. both the hardware limit switches and the emergency limit switches must be
connected.
Remember that you can actuate the emergency off switch at any time!
It has been assumed that your power section has been matched to the drive.
The first step
Power up the PLC
Switch on the 24 V supply
Connect the programmer to the IP 266
Start COM 266
(ON-LINE)
Keep an eye on the monitor's error line when making your entries. If a problem
occurs, it will be flagged on this line.
8-12
No CPU program need be available
at this point.
If you entered "yes" for "IP-STOP if
CPU-STOP" in the IP 266 machine
data, the CPU must be at RUN.
The CPU should not address the
IP 266 during the first phase of the
start-up procedure.
The power section is still off.
