AMP-0021 AMP-0006 Some potentiometers adjustments are dependent upon your amplifier model and version. Skip adjustment if you don’t see the Pot on your amplifier because it has a fixed value. Potentiometer Definition: Signal Gain Pot The SIG Pot affects how the amplifier converts the input signal to an RPM value. A low adjustment will cause the machine not to get up to the Rapid Traverse speed and it will generate a MOTOR OVERLOAD fault;... - Page 3 DC Amplifier Adjustment Procedure Machine with Scales: Before adjusting the amplifier, verify that scale cable (if applicable) is disconnected from the 1010 axis card of the corresponding axis amplifier to be adjusted. If it is connected (using the glass scale feedback), power down the machine, disconnect the cable, and then power up the machine.
- Page 4 For Metric Ballscrews the target value is 302. For Inch Ballscrews and Rotary tables the target value is 595. Use the SETP command to check the current Ballscrew Type if you’re not sure about which ballscrew you may have. The goal of the adjustment is to match the other axes so the system is dynamically balanced with all the XYZ axes.
