3.5.3 RH, RM, RL signal input compensation (Pr. 28 )
Pr. 810 Setting Torque Limit Input Method Operation
0 Internal torque limit
Parameter-set torque limit operation is performed.
Changing the torque limit parameter value by communication
enables torque limit to be adjusted by communication.
1 External torque limit Torque limit using the analog voltage from terminal 3 is made valid.
REMARKS
Refer to the Instruction Manual (basic) for details of the other parameters.
CAUTION
Whether the torque limit in the constant power range is set to constant torque limit or constant power
limit in the torque limit setting depends on the setting of Pr. 803 "constant power range torque
characteristic selection".
Related parameters
• Torque command bias adjustment ⇒ Pr. 904 "torque command terminal 3 bias" (Refer to page 190.)
• Torque command gain adjustment
⇒ Pr. 905 "torque command terminal 3 gain" (Refer to page 190.)
Pr. 24 to Pr. 27 Refer to Pr. 4 to Pr. 6 (page 77)
By entering 0 to ±10V into terminal 1 (speed setting auxiliary terminal), the speeds of the RH, RM and RL
signals (command speeds for multi-speed operation) can be compensated for.

CAUTION
• When "4 or 14" is set in Pr. 73, the compensation signal is input from terminal 2, not from terminal 1.
(Override function)
• Since terminal 1 is a multi-function selection terminal, its function varies with the Pr. 868 setting. Set
"0" in Pr. 868. Refer to Pr. 902 and Pr. 903 for calibration of the terminal 1.
