    Manual” mode for the drive. If the GSDA-CM-8 option card is in the Auto/Manual master slot and the GSDA-CM-8 jumper is in place for Auto mode, then the drive will also be in Auto mode. The GSD8 drive will then accept the target speed setting from the option card. Whether or not the GSD8 drive follows the GSDA-CM-8 analog input source depends on the analog input routing option on the serial card.
  • Page 6 SLOT 500 SLOT 200 (Install GSDA-CM-8 in slot 500 only) The GSDA-CM-8 is configured with default values that provide a checkout procedure to verify that the network is connected correctly and functioning. See the GSDA-CM-8 Item (Parameter) Table for further details.

  • Page 7: Using The Analog Input

    Using the Analog Input The GSDA-CM-8 has a built-in analog to digital converter. This input may be used in lieu of a digital pick-up signal or to control Target speed, current program, or frequency generator output frequency. To use this input with a potentiometer source, connect a pot wiper to Pin 7 of the serial interface port, pot high to the +5V terminal, pot low to the Common terminal.
  • Page 8 By selecting the voltage source type, the GSD8 drive will track a rapidly changing analog input signal. The GSDA-CM-8 samples the analog input signal at the rate of 50 milliseconds. Intended primarily as a feedback signal, replacing an encoder feedback signal or a leader signal when in a master/follower application;...
  • Page 9 • Analog Source Signal Maximum Value Minimum Value: “Minimum Value” refers to the lowest scaled value produced by the GSDA-CM-8, A to D converter when the analog source signal is at the lowest value. • For a potentiometer source signal, minimum value occurs with the potentiometer wiper at the closest position to the potentiometer terminal connected to the GSDA-CM-8, signal common;...
