TL signal terminal assignment ⇒ Set "26" in any of Pr. 180 to Pr. 183 and Pr. 187 (input terminal function selection). (Refer to page 61)

REMARKS

•When an analog signal is used to make external torque restriction, refer to page 47 for calibration of the No. 3 terminal (Pr. 904 "torque command No.3 bias" and Pr. 905 "torque command No.3 gain").

•When an analog signal is used to make regenerative torque restriction from the No. 1 terminal, perform calibration of the No. 1 terminal. (Pr. 919 "No. 1 terminl a bias (torque/magnetic flux)", Pr. 920 "No. 1 terminl gain (torque/magnetic flux)") Refer to page 47.

(3) Torque restrictions during acceleration and deceleration

You can set torque restrictions during acceleration and deceleration individually.

The following chart shows torque restrictions according to the settings of Pr. 816 "acceleration torque restriction" and Pr. 817 "deceleration torque restriction".

After -60<preset speed-speed<60r/min status has persisted for one second, acceleration/deceleration ends and it is judged as constant speed operation.

4.1.6Gain adjustment

As a simple tuning method, the Pr. 819 "easy gain tuning" function is available. (Refer to page 43.)

REMARKS

• For fine adjustment of gain, refer to the Instruction Manual (detailed))

•Manual gain adjustment (Pr. 820, Pr. 821, Pr. 830, Pr. 831)

•Speed feed forward control and model adaptive speed control are also available.
