*1 When the FR-A5AP is not fitted, the function names in parentheses are used.
*2 " in the Control Mode field indicates that the corresponding function is valid.
*3 Functions as the stall prevention operation level.
*4 The acceleration/deceleration pattern C setting (Pr. 29 = 4) is made valid when the FR-A5AP is fitted.
*5 Functions as an overspeed detection frequency under encoder feedback control and as an excessive speed
deviation detection frequency under vector control. Excessive speed deviation detection frequency is a parameter
available with an upgraded inverter. The parameter acts only as an overspeed detection frequency for a standard
inverter. Refer to the inverter manual for the availability of the excessive speed deviation detection frequency.
