Adjustment Procedure

 Caution:

The X–Axis motor may tend to run away, out of control, if the tach
wires are reversed.  If the axis moves in the wrong direction, the
motor wires are reversed.  If, however, reversing the leads doesn’t
stop a runaway motor, make sure the T (Tachometer) potentiometer
is not full counterclockwise.

1.

Apply a signal step input command between 0 and 10 VDC at positions 1 and 4
on the signal input connector. (Suggest 5 VDC input voltage)

2.

Slowly turn the (S) Signal pot 4 turns in the clockwise direction observing that
the motor shaft rotates at a reasonably controlled rate.

3.

Slowly turn the (C) Current pot 4 turns in the clockwise direction (motor shaft
speed may increase and stabilize).  If the X axis motor shaft runs to a high or
uncontrolled rate, reverse the tach wires coming to the signal input connector.

4.

If the X axis motor shaft rotates in the wrong direction for a given polarity of the
signal input voltage, reverse both the tachometer wires along with the red and
black motor power wires on the terminal block.

5.

If connected, verify that the Left and Right limit switches properly inhibit the axis
travel in the direction defined.  The normally open limits are activated when tied
to common.

6.

Slowly turn the (S) pot clockwise to increase the motor shaft speed to full
speed.

7.

If a high output voltage tachometer is used, it may be necessary to turn the (T)
pot a few turns counterclockwise to achieve the desired speed.

8.

Slowly turn the (C) pot to the full clockwise position if the servo control’s peak
current is less than the rated peak current of the motor.  If the peak motor
current is less than that of the servo control, a reduced current MUST be
maintained.

Note: The following 5 steps (9 through 13) are to be followed in setting up each axis

before connecting the servo motors to the equipment.  The following
procedure should also be used after the equipment has been installed with a
load and control applied for the final fine tuning.

9.

Slowly turn the (R) pot in the clockwise direction until the axis becomes
unstable and then turn the pot back one turn in the counterclockwise direction.
This adjustment is best done with a step input command.

10. If the motor shaft rotates with the signal input voltage at zero; slowly turn the (B)

pot to eliminate any motor shaft rotation.

11. If the motor shaft overshoots when stopping, turn the (T) pot in the

counterclockwise direction being careful not to turn to full counterclockwise.
Full counterclockwise on the (T) pot may cause the motor shaft speed to
become uncontrollable.

12. The (S) pot can now be adjusted to optimize the maximum response for the

given signal input voltage range.

13. Repeat the wiring instructions in Section 2 of this manual and the Start-up

procedure in this section for each servo motor and servo control card.
