4.1.6 Gain adjustment
As a simple tuning method, the Pr. 819 "easy gain tuning" function is available. (Refer to page 47.)
• You can select whether the torque limit in the constant
power range be constant torque limit (setting is "1") or
constant power limit (initial setting is "0"), using Pr. 803
"constant power range torque characteristic selection"
under torque limit operation.
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.
