Test Board Installation
IMPORTANT:
Press
E
-
STOP
to de-energize servos before installing the
test board.
1. Remove the cable attached to
J1
of the Servo Drive you wish to
monitor and connect it to
P1
of the test board.
2. Attach
W1
of the test board to
J1
of the servo.
3. Re-energize the servos.
Test Points
Refer to
Table 3
for a description of test points and signals.
Table 3, Servo Drive Test Board: Test Points and Jumpers
Test Point
Pin
Signal
TP1 3
Command Signal
TP2 4
Common for all servo signals and potentiometers.
All readings are referenced to TP2.
TP3 5
Tachometer
TP4 6
Motor Current output monitor. The scale factor is
1V = 5A.
TP5 9
Clamp input from the SCB. When pulled to chassis
ground, the servo’s output is forced to 0 VDC.
TP6 10
Fault output. When the servo card is faulted, the
output is pulled low. If TP6 is pulled to chassis
ground, the Servo is disabled and coasts to a stop.
JMP1 11
Command Signal Common. If removed, JMP1 will
open the common line at Pin 11 of J1.
JMP2 3
Common Signal. If JMP2 is removed, the
Command signal will open at Pin 3 of J1.
Jumpers
While troubleshooting, you can remove jumpers to isolate the Servo Drive
from the DAC outputs of the Motion Control Board during troubleshooting.
If Pin 2 of JMP1 and JMP2 are shorted together, the Servo Drive’s input
is fixed at 0 VDC; this can be useful in troubleshooting balance problems.
