Torque

Setpoints
This parameter is used to set the direction, gain, and bias of the RX2 input
terminal when this 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.
The bias and gain of the RX terminal may be trimmed at F476 and F477 ,
respectively.

• Provide a Run command (F and/or R).
• Set RX2 Input Point 1 Torque ( F226 ).
• Set RX2 Reference Point 1 ( F222 ) — the input analog signal level
that corresponds to the speed setting at RX2 Input Point 1 Torque .
• Set RX2 Input Point 2 Torque ( F227 ).
• Set RX2 Reference Point 2 ( F224 ) — the input analog signal level
that corresponds to the speed setting at RX Input Point 2 Torque .
• Provide a Run command ( F and/or R ).
Torque Control is accomplished by establishing an associated V/f output
pattern for a given RX2 level.
Once set, as the RX2 voltage changes, the ASD output speed and/or torque will
vary in accordance with the above settings.
This parameter sets RX2 Input Point 1 Torque and is the output torque value
that is associated with the setting of F222 .
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
additional information on the function of this terminal.

RX2 Input Point 2 Torque
Program

Torque

Setpoints
This parameter is used to set the direction, gain, and bias of the RX2 input
terminal when this terminal is used as the control input while operating in the
Torque Control mode.
Torque Control is accomplished by establishing an associated V/f output
pattern for a given RX2 input level and motor load.
This parameter sets RX2 Input Point 2 Torque and is the output torque value
that is associated with the setting of RX2 Reference Point 2 ( F224) .
This value is entered as -250 to +250% of the rated torque.
Direct Access Number — F227
