VI/II Input Point 1 Torque
Program Torque Setpoints
This parameter is used to set the gain and bias of the isolated VI/II terminal
when the VI/II terminal is used as the control input while operating in the
Torque Control mode.
The bias and gain of the VI/II terminal may be trimmed at F470 and F471,
respectively.
VI/II Torque Control Setup
Perform the following setup to allow the system to receive Torque Control
input at the VI/II terminal:
• Connect the input control current or voltage to the II input or the VI input,
respectively.
•Program Fundamental Standard Mode Selection Frequency Mode 1
VI/II.
•Program Fundamental Standard Mode Selection Command Mode
Selection Terminal Board.
•Set VI/II Input Point 1 Torque (F205).
•Set VI/II Reference Point 1 (F201) — the input analog signal level that
corresponds to the torque setting at VI/II Input Point 1 Torque.
•Set VI/II Input Point 2 Torque (F206).
•Set VI/II Reference Point 2 (F203) — the input analog signal level that
corresponds to the torque setting at VI/II 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 VI/II level.
Once set, as the VI/II voltage or current changes, the output torque of the ASD
will vary in accordance with the above settings.
This parameter sets VI/II Input Point 1 Torque and is the output torque value
that is associated with the setting of VI/II Reference Point 1 when operating in
the Torque Control mode.
This value is entered as 0% to 250% of the rated torque.
Note: When using the isolated VI/II terminal the IICC terminal must
be used as the return (negative) connection.

VI/II Input Point 2 Torque
Program Torque Setpoints
This parameter is used to set the gain and bias of the VI/II terminal when the
VI/II 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 VI/II level.
This parameter sets VI/II Input Point 2 Torque and is the output torque value
that is associated with the setting of VI/II Reference Point 2 when operating in
the Torque Control mode.
This value is entered as 0% to 250% of the rated torque.
See VI/II Input Point 1 Torque (F205) for more information on this setting.
