z Brake sequence function (Pr. 278 to Pr. 285)
Pr. 278 "brake opening frequency"
Pr. 279 "brake opening current"
Pr. 280 "brake opening current detection time"
Pr. 281 "brake operation time at start"
Pr. 282 "brake operation frequency"
Pr. 283 "brake operation time at stop"
Pr. 284 "deceleration detection function selection"
Pr. 285 "overspeed detection frequency"
This function is used to output from the inverter the mechanical brake opening completion signal timing signal
in vertical lift and other applications.
This function prevents the load from dropping with gravity at starting due to the operation timing fault of the
mechanical brake or an overcurrent alarm from occurring at a stop, ensuring secure operation.
z The mechanical brake opening completion signal may either be entered or not entered into the inverter.
z This function is only valid when "7" or "8" is set in Pr. 60 to select brake sequence mode. (With the
exception of Pr. 285)
