1.22 Alarm 27 – Pusher Can Not Push Bar
e 2 7 : P U S H E R C A N N O T
Alarm27:
P U S H B A R !
Description :
If the interface implements a start signal from the bar feeder to the lathe, then the
part length is checked BEFORE the chuck on the lathe closes. If the length is too
short then this alarm occurs (The difference to Alarm 17 is that Alarm 27 already
occurs before the chuck is closed. This is only possible if the interface includes a
start signal from the bar feeder to the lathe.).
Solution :
Check the value of parameter F2.
Make sure nothing is blocking the pusher.
