Torque Reference Setpoint #1

This parameter is used to set the direction, 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.

RX Input Torque Control Setup

Perform the following setup to allow the system to receive Torque control input at the RX input terminal:

•	Program Utilities	Command and Frequency Settings Command
	Mode Select Terminal Block.
•	Program ⇒Utilities ⇒Command and Frequency Settings ⇒Frequency#1
	Mode Select ⇒RX.
•	Provide a Run command (F and/or R).

Torque Control

Perform the following setup to allow the system to perform Torque control from the RX input terminal:

•	Set RX Torque Reference Setpoint #1,
•	Set the RX⇒input signal level (RX⇒Speed Ref #1) that represents the⇒RX
	Torque Reference Setpoint #1,
•	Set RX Torque Reference Setpoint #2, and
•	Set the RX input signal level (RX Speed Ref #2) that represents the RX
	Torque Reference Setpoint #2.

This is accomplished by establishing an associated V/f output pattern for a given RX input level.

This parameter sets RX Torque Reference #1 and is the output torque value that is associated with the setting of RX Speed Reference #1 when operating in the Torque control mode.

This value is entered as -250 to +250% of the rated torque.

This parameter is used to set the direction, 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.

This is accomplished by establishing an associated V/f output pattern for a given RX input level.

See RX Torque Reference Setpoint #1 for further information on this setting.

This parameter sets RX Torque Reference Setpoint #2 and is the output torque value that is associated with setting of RX Speed Reference Setpoint #2 when operating in the Torque control mode.

This value is entered as -250 to +250% of the rated torque.
