RTS 2nd Generation SERVO AMPLIFIER

PVD 3487 GB 03/2004
7.1 Speed loop rapid adjustment
* Offset adjustment
Once ambient temperature is stabilised, adjust zero speed to
the mid-position with the "SPEED OFFSET" potentiometer
on the front panel.
* Speed adjustment
The "SPEED ADJUST" potentiometer produces fine
calibration of speed for a given reference.
* Gain adjustment
By increasing gain, the servo motor becomes more rigid.
Turn the "GAIN" potentiometer clockwise until the motor is
unstable and vibrates.
Then turn the potentiometer back one or two turns. If there is
a large load on the potentiometer, the potentiometer
adjustment range may be inadequate and resistance R101
will have to be increased.
