118 H9 ASD Installation and Operation Manual
RX2 (AI1) Input Point 1 Rate
Program ⇒ To r que ⇒ Setpoints
This parameter is used to set the gain and bias of the RX2 (AI1) input terminal
when the RX2 (AI1) terminal is used as the control input while operating in the
Torque Control mode.
Note: The Expansion IO Card Option 1 option board (P/N ETB003Z)
is required to use this terminal.
RX2 (AI1) Input Torque Control Setup
Perform the following setup to allow the system to receive Torque Control
input at the RX2 (AI1) input terminal:
• Program ⇒ Fundamental ⇒ Standard Mode Selection ⇒ Frequency Mode
⇒ RX2.
• Program ⇒ Fundamental ⇒ Standard Mode Selection ⇒ Command Mode
Selection ⇒ Terminal Block.
• Provide a Run command (F and/or R).
Torque Control
Perform the following setup to allow the system to perform Torque Control
from the RX2 (AI1) input terminal:
•Set RX2 (AI1) Input Point 1 Rate (F226).
•Set RX2 (AI1) Input Point 1 Setting (F222) — the input analog signal
level that corresponds to the speed setting at RX2 (AI1) Input Point 1
Rate.
•Set RX2 (AI1) Input Point 2 Rate (F227).
•Set RX2 (AI1) Input Point 2 Setting (F224) — the input analog signal
level that corresponds to the speed setting at RX Input Point 2 Rate.
• Provide a Run command (F and/or R).
Torque Control is accomplished by establishing an associated V/f output
pattern for a given RX2 (AI1) input level.
Once set, as the RX2 (AI1) input voltage changes, the ASD output speed and/or
torque will vary in accordance with the above settings.
This parameter sets RX2 (AI1) Input Point 1 Rate and is the output torque
value that is associated with the setting of RX2 (AI1) Input Point 1 Setting
when operating in the Torque Control mode.
This value is entered as -250% to +250% of the rated torque.
See the Expansion IO Card Option 1 instruction manual (P/N 58685) for
more information on the function of this terminal.
