E31 Speed Detection (FDT) (Detection level)
E36
(Speed Detection 2 (FDT) (Detection level))
E32 Speed Detection (FDT) (Hysteresis)
E31.E36 and E32 specify the speed detection level and hysteresis band width for the output signal
FDT or FDT2 assigned to a general-purpose programmable output terminal by any of E20 to E24
and E27.
■
Speed detection level (E31 or E36)
The output signal FDT or FDT2 are turned ON when the detected speed has exceeded the speed
detection level specified by E31 or E36 respectively.
- Data setting range: 0.00 to 6000 (r/min)

Data setting range changes depending on the number of poles of motor etc. For details, refer to
section 2.2.
■
Speed detection hysteresis (E32)
The FDT is turned OFF when the detected speed becomes lower than the "Detection level (E31 or
E36) - Hysteresis band width (E32)."
- Data setting range: 0.00 to 900 (r/min)

Data setting range changes depending on the number of poles of motor etc. For details, refer to
section 2.2.
■
Speed detection
Setting any of E20 to E24 and E27 data to "2" assigns the output signal FDT or to "31" assigns the
output signal FDT2 to the specified general-purpose programmable output terminal. The FDT or
FDT2 signal comes ON when the detected speed has exceeded the speed detection level (E31 or
E36). It goes OFF when the detected speed becomes lower than below the "Detection level (E31 or
E36) - Hysteresis band width (E32).
Reference speed is used for detection speed to change when the torque vector is control
is used.
