5.3.20 Frequency Detection
FDT-freq. [ADV: Code No. 73] Frequency detection level
Range: 0.50 - SER 15 Hz.
(Factory Default: 60.0 Hz)
FDT-band [ADV: Code No. 74] Frequency detection band
Range: 0.00 - 30.0 Hz.
(Factory Default: 1.00 Hz)
This function is used to operate one of the multi-function outputs. If a Multi-Function
Output is programmed for FDT_HI the output signal is set once the drive reaches FDT
frequency [ADV: Code No. 73], and resets when the drive frequency falls below FDT
frequency less FDT band [ADV: Code No. 74]. See Fig. 5.3.19. If a Multi-Function
Output is programmed for FDT_PULSE the output pulses as the increasing frequency
passes through FDT frequency and again as the decreasing frequency passes through
FDT frequency less FDT band. If a Multi-Function Output is programmed for FDT_BAND
the output sets when the drive output is at the requested frequency plus or minus the
FDT band. See Section 5.2.4 for more information regarding the Multi-function output.

5.3.21 Speed Display Scaling Factor
Mul factor [ADV: Code No. 75] Scaling factor for USE 04 display
Range: 0 - 999
(Factory Default: 100)
Div factor [ADV: Code No. 76] Scaling factor for USE 04 display
Range: 1 - 999
(Factory Default: 100)
This function is used to scale the display Speed [USE: Code No. 04]. The values in Mul
factor [ADV: Code No. 75] and Div factor [ADV: Code No. 76] can be adjusted to account
for gear ratios.
5.3.22 LED Check
LED check [ADV: Code No. 77] This function is not used.
