5.44.8.4 Master Follower Interlock
As Interlock signals are sent from Serve Drive, Leader Drive puts together through Communication
Line. Every Trip such as HAND State or OFF State of Serve Drive is processed by Interlock in Leader
Drive .
This is, other Server Drives keep performing Master Follower function except the cases that it is in
HAND/OFF State or there are trips
If Leader Drive is HAND State or OFF state, Master Follower system is not activated.
In case that Pipe Broken and Interlock Trip are caused in Leader Drive, every drive operating is
stopped and Master Follower keeps performing the function except Leader Drive if there is
another Trip.
(Leader Drive executes PID control and overall system control consistently.)
In this operating priority (M1 M2 M3 M4 M5 M6 M7 M8), if interlock3 or any

trip and HAND/OFF State are caused, the motor is activated in this order(M1 M2 M4 M5
