Torque Limit
Signal
The Torque Limit output [TRQ] works in conjunction with the torque limit function covered in
the intelligent input section. The torque limit function limits the motor torque according to the
criteria selected by parameter B040. When torque limiting occurs, the [TRQ] output turns ON,
then turns OFF automatically when the output torque falls below the specified limits. Note that
the Torque Limit input [TL] must be ON in order to enable torque limiting and its related
output, [TRQ]. See
“Torque Limit” on page 4–30
in the intelligent input section.

Series inverters accumulate the total hours in Run Mode (run time) and the total hours
of power-ON time. You can set thresholds for these accumulating timers. Once the threshold is
exceeded, an output terminal will turn ON. One use of this is for preventative maintenance. A
signal light or audible alert could signal the need for servicing, calibration, etc.
The two outputs [RNT] and [ONT] share the same time threshold parameter, B034. Typically,
you will use either the [RNT] or the [ONT] output only—not both at once. These outputs are
useful for the notification that a preventative maintenance interval has expired.
