Example Settings for the OL
(Speed Reference Setting)
Given the following fixed parameter settings, the following table lists examples of the
OL
• No. 5 (Number of Digits Below Decimal Point) = 3
• No. 34 (Rated Motor Speed) = 3,000 min
• No. 36 (Number of Pulses per Motor Rotation) = 65,536 P/R

If the output ratio is 25% ... 25 ÷ 0.01 = 2,500
50% ... 50 ÷ 0.01 = 5,000
75% ... 75 ÷ 0.01 = 7,500
