Control logic
When truck is not on work-position and test-position, truck allow to rack-out only.
Only all interlock signals are on, and the controller is no fault, the controller will allow operation.
When the rack-in process brake occurs, stop the current operation and drive the motor to test-position, if in the retum process,brake happen again, stop the motor running; rack-out process when the brake occurs, stop the current operation and reverse drive motor run 300mS.
When a timeout (timeout is set to 70S) not to reach the designated position occurs, should be returned to test-position.
After motor is on test-position, delay 400mS, then reverse run 20mS.
Over-current settings, first 15 second in rack-in process , 220Vset 1.2A, 110V set 2A, 125V set; In time remaining, 220V set 4A,110V to 5A. 125V set 6.5A. First 7 second in rack-out process, 220V set 4A, 110V set 5A, 125V set 6.5A; In time remaining, 220V set 1.2A, 110V set 2A, 125V set 3A.
