TU-11/12/15 Servo Reference procedure.
Mechanical setup
WARNING: A portion of this procedure is performed with the power cabinet open and energized.
Therefore, it should only be performed by qualified personnel.
1. When the RAM is at top dead center the cam on the back of the crimping unit should be at 45 degrees.
The cam edge will align with the target on the left prox. Switch. See picture below.
The prox switch on left is the direction prox. When master starting the machine, the control will use this
prox to determine which way to rotate the motor to return the ram to the home position. If this prox is not
working the ram could move through bottom dead center before it goes to the home position. The prox
switch on the right is the reference prox. This prox is only used when the machine is master started after
a power down.
