External torque restriction
REMARKS
Refer to the Instruction Manual (basic) for details of the other parameters.
CAUTION
Whether the torque restriction in the constant output range is set to constant torque restriction or
constant output restriction in the torque restriction setting depends on the setting of Pr. 803 "constant
output range torque characteristic selection".
Related parameters
• Torque command bias adjustment ⇒ Pr. 904 "torque command No. 3 bias" (Refer to page 202.)
• Torque command gain adjustment ⇒ Pr. 905 "torque command No. 3 gain" (Refer to page 202.)
Pr. 24 to Pr. 27
Refer to Pr. 4 to Pr. 6 (page 90)

RH, RM, RL signal input compensation (Pr. 28
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.

compensation
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.
Related parameters
• Multi-speed setting ⇒ Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239 (multi-speed setting) (Refer to page 90.)
• RH, RM, RL signals⇒ Pr. 180 to Pr. 183, Pr. 187 (input terminal function selection) (Refer to page 163.)
• Speed compensation using terminal 2 ⇒ Pr. 73 "speed setting signal" (Refer to page 125.)
• Function assignment to terminal 1 ⇒ Set "0" in Pr. 868 "No. 1 terminal function assignment" (Refer to page 195.)
• Pr. 59 "remote setting function selection" ⇒ Refer to page 116.
• Calibration of terminal 1 ⇒ Pr. 902 "speed setting No. 2 bias", Pr. 903 "speed setting No. 2 gain" (Refer to page 202)
Operation selection functions 1 (Pr. 17 to Pr. 37)
Parameter-set torque restriction operation is performed.
Changing the torque restriction parameter value by communication
enables torque restriction to be adjusted by communication.
Torque restriction using the analog voltage from the terminal 3 is
made valid.
