This parameter is used to set the direction, gain, and bias of the RX input
terminal when this terminal is used as the control input while operating in the
Speed Control or the Torque Control mode.
This parameter sets the RX input level that represents RX Reference Point 2
(frequency) (direction/torque/frequency). The range of values for this parameter
is -100 to +100% of the -10 to +10 VDC RX input signal range.
See RX Reference Point 1 ( F216 ) for additional information on this setting.

Speed Reference Setpoints
This parameter is used to set the direction, gain, and bias of the RX input
terminal when this terminal is used as the control input while operating in the
Speed Control mode.
This parameter sets RX Point 2 Frequency and is the frequency that is
associated with the setting of RX Reference Point 2 ( F218 ).
See RX Reference Point 1 ( F216 ) for additional information on this setting.

Setpoints
This parameter is used to set the direction, gain, and bias of the RX input
terminal when this 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.

• 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 ( F216 ).
This value is entered as -250 to +250% of the rated torque.
