Subroutine 52 - Turret2_Bin_T (Turret With Binary Coding Function) - Siemens SINUMERIK 808D Operating Instructions Manual

3.25 Subroutine 52 - TURRET2_BIN_T (turret with binary coding
function)
Purpose
Subroutine 52 is used to control the turret with encoder positioning signals and function of
dual-direction adjacent tool change. Contact the turret vendor for the working theory and the
timing diagram of a tool change.
During a tool change, the NC interface signals "Read-in disable" (DB3200.DBX6.1) and
"Feedhold" (DB3200.DBX6.0) are set, so the part program can continue running only after
the tool change action.
The turret position action is forbidden in case of an emergency stop, turret motor overload or
program test/simulation.
This subroutine can activate the following alarms:
● Alarm 700022: Turret motor overload
● Alarm 700023: Programmed tool number higher than the max. tool number of the turret
● Alarm 700024: Wrong setting of the max. tool number for the turret
● Alarm 700026: Not able to find expected tool in monitor time
● Alarm 700011: Not able to lock tool in expected time
