Appendix 3-2 Changed functions
(1) Addition of X74 signal
The change applies to the July 2006 production or later.
Magnetic flux decay output shutoff signal (X74) becomes a valid input by setting "74" in any of Pr. 178 to Pr. 189 (Input
terminal function selection). (Refer to page 242)
(2) Writing/reading of Pr. 296 Password lock level and Pr. 297 Password lock/unlock, and output of
Password locked error (LOCD) (Refer to page 318)
The changes apply to the April 2010 production or later.
(3) Magnetic flux decay output shutoff function (Pr. 850 = "2")
The change applies to the December 2010 production or later.
Use this parameter to activate the magnetic flux decay output shutoff (Pr. 850 = "2") under Real sensorless vector control to
decay the leftover magnetic flux before shutting off outputs. (Refer to page 206)
(4) Addition of the stop-on contact and the load torque high-speed frequency control selection
(Pr. 270 = "11 or 13")
The change applies to the December 2010 production or later.
Use this parameter to enable/disable E.OLT (Stall prevention stop) detection under stop-on contact control.
