Mills using
Servo Dynamics direct replacement of Westamps.
When plugging the J1 Connector onto the Servo Dynamics 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 IPM in either direction. If an imbalance of
voltage occurs, adjust (BAL) to get both directional voltages
within .050 vdc of each other.
3. Turn (CMP/COMP) 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
