Balancing the DSP
2
Board (F6)
On systems that use an ANILAM Servo Amplifier Board (see Figure 6,
Digital Brushless AC Servo Amplifier, P/N 33001279 ), measurements for
this procedure can be made at the J2 input connector with the Servo
Amplifier Test Board, (see Figure 4, ANILAM Servo Amplifier Test Board,
P/N 33001399 ).
NOTE: If ANILAM did not provide the servo amplifiers, follow the
guidelines for balancing supplied by the manufacturer.
Refer to Figure 5, ANILAM DSP2 Board Balance Pots, P/N 33001102 .
Measure command voltages across TP1 and TP2 of the test board.
NOTE: These signals can also be found on Pin #1 and Pin #3 of the J2
input connector on the ANILAM Servo Amplifier Board.
All DSP
2
Boards are adjusted at the factory and should be within limits.
Only balance the DSP
2
Board if it is not at 0 VDC (±0.001 V).
NOTE: On 4200T systems, the DSP
2
Board is located inside the CNC
console. Open the CNC chassis by loosening the thumbscrews
and opening the cover.
Balance the DSP
2
Board with the
servos off, initially . Next, verify the DSP
2
Board balance with
the servos on, and correct for voltage offset as required.
1. Press Balance ( F6 ) to output a zero voltage signal to the axis.
2. Press
START
.
3. Refer to Figure 5, ANILAM DSP2 Board Balance Pots, P/N 33001102 .
Make adjustments for axis outputs 0–3 on the DSP
2
Board at
potentiometers R108-R111 respectively.
4. Adjust the potentiometer for the selected axis until the voltage across
the pins is 0 VDC (
±
0.001 V).
5. Press MANUAL ( F4 ) to cancel the test.
