Mills using
Westamp Servo Amplifiers.
When plugging the J1 Connector onto the Westamp Board, ensure
Pin J1 Connector plugs into Pin 1 on J1 Connector of the new
board. The J2 Connector is not used. Also note that Pins
13,14,15 are not used on the J1 Connector.
Tool Requirements:
a. Voltmeter
b. Small Screwdriver
Procedure:
1. On Servo Control Board, Connectors J2 (X), J3 (Y), and J4
(Z), Connect meter to Pins 8 and 9 for axis to be adjusted.
2. Power Servos Up, adjust SIG to achieve .9 vdc - B
Series (.000"), .65 vdc - BX Series (.0000")
of DAC at 25 IMP in either direction. If an imbalance of
voltage occurs, adjust BAL to get both directional voltages
within .050 vdc of each other.
3. Turn TC CW until motor oscillates, then CCW until motor
stops, then an additional 4 turns CCW.
4. Now zero axis and fine tune BAL pot to achieve CRT readings
of .0000.
Caution: Use Adjustments below
only after performing above procedure
and not
achieving the desired results.
Adjust Pots :
AUX
20 turns CCW
SIG
20 turns CW then 10 turns CCW
TAC/TACH 20 turns CW
CMP/COMP 20 turns CW then 10 turns
CCW
CL/CLM
20 turns CW
BAL
20 turns CW then 10 turns CCW
