Rockwell Automation Allen-Bradley Kinetix 5100 - Scaling of Analog Command (Torque Mode)

Scaling of Analog Command (Torque Mode)
The motor torque command is controlled by the analog voltage difference
between the T_REF and GND analog signals. The torque slope and its range
can be adjusted by the Analog to Torque Scale parameter.
Motor torque command is based on the following equation:
If the ID148 (P1.041) parameter is set at its default setting of 100 and the
external analog input voltage is 10V, the torque command is 100% of the rated
torque.
If the ID148 (P1.041) parameter is set to 300 and the external analog input
voltage is 10V, the torque command is 300% of the rated torque.
If the ID148 (P1.041) parameter is set at its default setting of 100 and the
external analog input voltage is 5V, the torque command is 50% of the rated
torque.
In Speed, PT and PR Modes set the torque limit corresponding to 10V (max.
voltage) for analog torque limit.
