CAUTION
⋅ When the acceleration/deceleration time (Pr. 7, Pr. 8, etc.) setting under Real sensorless vector control or vector control is 0s,
the S-pattern acceleration/deceleration A to D (Pr. 29 = "1, 2, 4, 5") is linear acceleration/deceleration.
⋅ Set linear acceleration/deceleration (Pr. 29 = "0 (initial value)") when torque control is exercised under Real sensorless vector
control or vector control. When acceleration/deceleration patterns other than the linear acceleration/deceleration are selected,
the protective function of the inverter may function.
