 ATTENTION:
When Y2/DO terminal is used as high-speed pulse output (set by P23.02), delay time set by
P21.05 is disabled.
Enabled state of digital

 Unit's place: Y1
0: Positive logic; ON when current passes through
1: Negative logic; ON when no current passes through
 Decade: Y2 (same as Y1)
 Hundreds place: relay 1 output
0: Positive logic; ON when there is coil excitation
1: Negative logic; ON when there is no coil excitation
 Thousands place: Reserved
Wiring diagram of digital output terminal is shown as Fig. 5-17:

doubling technology(FDT)
 Unit's place: FDT1 detective object
0: Set value of speed (frequency after Accel/Decel)
FDT1 output frequency is the command frequency after Accel/Decel.
1: Detected speed value
FDT1 output frequency is actually detected or identified frequency. If the drive is under V/f
pattern, it should be output frequency.
 Decade: FDT2 detective object
0: Set value of speed (frequency after Accel/Decel)
FDT2 output frequency is the command frequency after Accel/Decel.
1: Detected speed value
FDT2 output frequency is actually detected frequency or frequency after autotuning. If the
drive is under V/f pattern, it should be output frequency.
