control the current drawn. The motor drivers are supplied with 24V
to achieve rapid current increase and good torque. Each phase of the
motor can be supplied with up to 1.5 A, which is regulated by the
software independently of the step rate. U1840 is used for synchro-
nizing the pulse width modulation to the drivers to prevent high
peak values in the current drawn.
6.9 Control Panel
The control panel is made up of a LCD display with 4 x 40 charac-
ters and a keypad with 22 push-buttons. The function buttons control
the menu choices shown on the display. The numeric and alphanu-
meric keys are used to enter parameters and for setups.
