When enabled at F810, this parameter is used to allow the user to set the gain
and bias of the speed control input to the drive when the speed control signal is
received via the source selected at F810.
Gain and Bias Settings
When operating in the Speed Control mode and using one of the control
sources from Settings above, the settings that determine the gain and bias
properties of the input signal are:
Communications Reference Speed Setpoint #1 (frequency) (F812),
•
•
the communications input signal value that represents Communications
Reference Speed Setpoint #1 (frequency): F811,
Communications Reference Speed Setpoint #2 (frequency) (F814), and
•
•
the communications input signal value that represents Communications
Reference Speed Setpoint #2 (frequency): F813.
Once set, as the input signal value changes, the output frequency of the drive
will vary in accordance with the above settings.
This parameter sets the Communications Reference input value that represents
Communications Reference Speed Setpoint #1 (frequency). This value is
entered as 0 to 100% of the Communications Reference input value range.
