When enabled via the Communications Reference Select parameter, this parameter is used to allow the user to set the gain and bias of the speed control input to the ASD when the speed control signal is received via the source selected at the Communications Reference Select parameter.
Gain and Bias Settings
When operating in the Speed Control mode and using one of the control sources from the Communications Reference Select parameter, the settings that determine the gain and bias properties of the input signal are:
• Communications Speed #1 (Hz),
• the communications input signal value that represents Communications Speed #1 (Hz),
• Communications Speed #2 (Hz), and
• the communications input signal value that represents Communications Speed #2 (Hz).
Once set, as the input signal value changes, the output frequency of the ASD will vary in accordance with the above settings.
This parameter sets the Communications Reference input value that represents Communications Speed #1. This value is entered as 0 to 100% of the Communications Reference input value range.
Changes made to this parameter require that the power be cycled (Off then On) for the changes to take effect.
