Setpoints
This parameter is used to set the gain and bias of the RX input terminal when
the RX terminal is used as the control input while operating in the Torque
Control mode.
The bias and gain of the RX terminal may be trimmed at F474 and F475 ,
respectively.
RX Torque Control Setup
Perform the following setup to allow the system to receive Torque Control
input at the RX input terminal:

• Set RX Input Point 1 Torque ( F220 ).
• Set RX Reference Point 1 ( F216 ) — the input analog signal level that
corresponds to the torque setting at RX Input Point 1 Torque .
• Set RX Input Point 2 Torque ( F221 ).
• Set RX Reference Point 2 ( F218 ) — 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 RX input level.
Once set, as the RX input voltage changes, the ASD output speed and/or torque
will vary in accordance with the above settings.
This parameter sets RX Input Point 1 Torque and is the output torque value
that is associated with the setting of RX Reference Point 1 when operating in
the Torque Control mode.
This value is entered as -250% to +250% of the rated torque.
Direct Access Number — F220
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — -250.00
