Setpoints
This parameter is used to set the gain and bias of the isolated VI/II input
terminals 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.

• Set VI/II 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 Point 1 Torque.
• Set VI/II 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 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 Torque Reference Setpoint 1 (%) and is the output torque
value that is associated with the setting of VI/II Reference Point 1 ( F201 )
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 Point 2 Torque
Program

Torque

Setpoints
This parameter is used to set the gain and bias of the VI/II input terminals when
either 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 Point 2 Torque (%) and is the output torque value
that is associated with the setting of F203 .
This value is entered as 0 to 250% of the rated torque.
See F201 for additional information on this setting.
