•Acceleration Time And Deceleration Time Change (Setting：07)
•The acceleration time and deceleration time can be changed through the control
circuit terminal g~j
as described on page 39.
•External Baseblock (A Contact) (Setting：08)
•External Baseblock (B Contact) (Setting：09)
•With either of these settings, the multi-function input terminal controls its
inverter baseblock operation.
•During running : As an external baseblock signal is detected, the digital operator
will display a “B.B. Alarm”. Then, the inverter output is blocked. After the
baseblock signal is cleared, the motor will resume running according to its then
reference signal.
•During deceleration : An external baseblock signal is input, the digital operator
will display “ B.B. Alarm”, the inverter is blocked from output and the output
frequency will drop to zero. The motor will then coast to stop freely. After this
external baseblock signal is cleared, the inverter will stay in stop mode.
•Acceleration and Deceleration Ramp Hold (Setting:10)
•With this setting, the signal of Acceleration/deceleration ramp hold (input from
the multi-function input terminals) will pause the Acceleration/deceleration of
motor and maintain the then output frequency. The motor will coast to stop if an
OFF command is input while the acceleration / deceleration ramp hold input is
ON, the then output frequency will be memorized and the command of
Acceleration/deceleration ramp hold is released.
