RX2 Reference Point 1
Program Frequency Speed Reference Setpoints
This parameter is used to set the gain and bias of the RX2 terminal when the
RX2 terminal is used as the control input while operating in the Speed Control
mode or the Torque Control mode.
Note: The Expansion IO Card Option 1 option board (P/N ETB003Z)
is required to use this terminal.
This parameter sets the RX2 level that is associated with RX2 Input Point 1
Frequency when operating in the Speed Control mode or is associated with
the RX2 Input Point 1 Torque when operating in the Torque Control mode.
The bias and gain of the RX terminal may be trimmed at F476 and F477,
respectively.
RX2 Speed Control Setup
Perform the following setup to allow the system to receive Speed control input
at the RX2 terminal:
•Program Fundamental Standard Mode Selection Frequency Mode
1 RX2.
•Program Fundamental Standard Mode Selection Command Mode
Selection Terminal Board.
•Set RX2 Input Point 1 Frequency (F223).
•Set RX2 Reference Point 1 (F222) — the input analog signal level that
corresponds to the speed setting at RX2 Input Point 1 Frequency.
•Set RX2 Input Point 2 Frequency (F225).
•Set RX2 Reference Point 2 (F224) — the input analog signal level that
corresponds to the speed setting at RX Input Point 2 Frequency.
•Provide a Run
command (F and/or R).
Once set, as the RX2 voltage changes, the ASD output speed and/or torque will
vary in accordance with the above settings.
This parameter value is entered as -100% to +100% of the RX2 signal range.
See the Expansion IO Card Option 1 instruction manual (D/N 58685) for
more information on the function of this terminal. See parameter F476 and
F477 for information on fine-tuning this terminal response.

RX2 Input Point 1 Frequency
Program Frequency Speed Reference Setpoints
This parameter is used to set the gain and bias of the RX2 terminal when the
RX2 terminal is used as the control input while operating in the Speed Control
mode.
This parameter sets RX2 Input Point 1 Frequency and is the frequency that is
associated with the setting of RX2 Reference Point 1 when operating in the
Speed Control mode.
See RX2 Reference Point 1 (F222) for more information on this setting.
