Acc. / Dec. modes selection
Unit: Acc. / Dec. modes selection
0: Linear Acc. / Dec.. Output frequency increase or decrease according to constant slope.
1: S curve Acc. / Dec.. Output frequency increase or decrease accoring to S curve.
• T5: setting acc time; T7: actual acc time. T6: setting dec time; T8: actual dec time.
Ten: Reference frequency for Acc. / Dec. time
0: Max frequency (F00.06).
1: Setting frequency.

Acc time is the time that HD3N accelerates from 0 Hz to reference frequency in linear form.
Dec time is the time that HD3N decelerates from reference frequency to 0Hz in linear form.
• Reference frequency is set by tens of F03.00. It supports acc time or dec time only, refer to figure in
F03.00.
Switching of Acc. / Dec. time:
• Select Acc. / Dec. time by No. 26/27 of DI terminal or F03.09/F03.10 when HD3N is running.
Switching of Acc. / Dec. mode:
• The Acc. / Dec. modes (linear or S curve) can be set by F03.00 or No 28 function of DI terminal.
Note: If braking units are not adopted correctly, dec speed is too high or load interia is too large, over-pressure
will occur to HD3N. Please select suitable braking unit, increase the dec time or adjust F19.18/F19.19.
F03.09 Switching frequency of acc time 1 and 2 0.00 - Upper limit
When running frequency is lower than F03.09, acc time 2 is adopted; otherwise acc time 1 is adopted.
• This function is invalid when Acc. / Dec. time is selected by DI terminal (DI = 26/27).
F03.10 Switching frequency of dec time 2 and 1 0.00 -
Upper limit
frequency [0.00Hz]
When running frequency is lower than 03.10, dec time 2 is adopted; otherwise dec time 1 is adopted.
• This function is invalid when Acc. / Dec. time is selected by DI terminal (DI = 26/27).
