Question/Problem
OLS
206 Has F_0122 Error: X Axis EE11A and EE11B Not On after Homing
Environment
Lenze PLC
Answer/Solution
Steps to troubleshoot:
In order to check
if shuttle is at the home slot, check E11A and E11B sensors are ON, E13 Sensor is
ON, and x axis position value should be zero that indicates the first slot.
Step1: Check for EE11A and E11B signals, make sure
both the signals are ON after homing is completed
To check for these sensor value,
Follow the below step:
•
Connect the
shuttle to the power supply.
•
Move the shuttle inside
the railing and monitor I/O to the PLC
•
If these signals
are coming back to the PLC(Signal values are True in code), that means there is
no issue with the sensors and shuttle is working fine on the railing.
Step 2:
Next step is to see for the homing sensor EE13, if this is ON that
means, it can see the reflector and shuttle is at home slot that is slot1.
Step3:
Check x axis position
value in PLC code, it should be zero which indicates the first slot.
Step 4: Next step is to check, while shuttle is
moving towards the home slot is centered on the rail slot or not.
Follow below steps:
-
Check guide
wheels are aligned properly.
-
Clean the rail
-
Clean
shuttle wheels, idle and drive wheels
-
Clear bearings
on wheels
Resolution:
Guide wheels were not aligned properly for OLS 206.
Site removed plc and Wi-Fi module from shuttle 206 and place
it in one of the spare shuttles which they have and it is working fine.
