L1600 - Description
L1600 (Z-Motor Driver) controls the AC-motor that
drives the unit up and down. Membrane switches on
the side of the vertical carriage are used to activate the
AC-motor.
Micro switches at the top and bottom of the column
monitor the upper and lower positions of the Z-move-
ment. Based on the logic on the circuit board, the move-
ment of the AC motor is enabled or prohibited. Three
triacs control the Z-motor currents. Outputs are opto-
coupled from the user inputs with TLP3063 circuits. The
board also includes light controls for the laser position-
ing lights.
L1600 also sets the autotransformer input winding.
There are three SET signals, SET 100V, SET 115V and
SET 230V that control what mains voltage goes to what
input winding of the autotransformer.
The auto transformer output voltage is always 230 VAC
