Parameter Units Level
24-FSEL - Speed Reference Selector L2
Note: Reference 21-MODE and parameter 32-FMAX thru 38-F7 for a thorough understanding of this
parameter setting.
This parameter is used to define the frequency command signal source when operating from other than the
inverter's keypad. That generally means the definition of signal types applied to either the VIN or CIN
terminals. This parameter can also be used to re-define terminal strip speed control (referenced in 21-
MODE) as keypad operation.
The proper usage of this parameter is dependent on the selection made at 21-MODE. Typically, no
changes are necessary at this parameter.
0 VIN/CIN Terminal input, speed pot or external 0-2, 0-10 VDC or 4-20 mA 1
1 -VIN/CIN Terminal input, inverse speed control
2 VIN Same as Code 0, but external speed pot current monitored. If
any of the three connections are broken, the drive will stop. Not
for use with any externally supplied voltage or current references.
3 VIN Terminal input, follows the 6FS (6X) output of another WFC series inverter. 1, 3
4 FPT1 Pulse train input at VIN, 0-1 kHz (6-10 VDC peak minimum) 1
5 FPT2 Pulse train input at VIN, 0-10 kHz (6-10 VDC peak minimum)
6 FKPAD Keypad Speed Reference 2
7 FEXT2 External speed reference 2 programmed via 26-FEXT2 (default = 0 Hz)
8 FEXT1 External speed reference 1 programmed via 25-FEXT1 (default = 0 Hz)
9 F2 Programmable via 33-F2 (default = 5 Hz)
10 F3 Programmable via 34-F3 (default = 20 Hz)
11 F4 Programmable via 35-F4 (default = 40 Hz)
12 F5 Programmable via 36-F5 (default = 60 Hz)
13 F6 Programmable via 37-F6 (default = 0 Hz)
14 F7 Programmable via 38-F7 (default = 0 Hz)
15 FMAX Programmable via 32-FMAX (default = 60 Hz)
19 VIN Terminal input, follows the 6FS (48X) output of another WFC series inverter. 1, 3
Notes:
1. Data codes 0 thru 5 define the type and response characteristic of input speed signal connected to the
terminal strip of the inverter.
2. If speed control is programmed from the keypad at parameter 21-MODE, the selection at parameter 24
is ignored.
3. Frequency of input signal determined by parameter 88-FRO. If parameter 24-FSEL is set data code 19,
adjust the J2 jumper (see page 15, figure 2.8) to the 0-2V position for better resolution. The table that
follows notes the maximum operating frequency when using this data code and parameter 83-PWM.
Consult the factory with any questions.
The maximum running frequency available when using data code 19 (48x pulse train from another WFC
HT
series inverter) is limited by the operating carrier frequency. When selecting the carrier frequency at
parameter 83-PWM and parameter 24-FSEL is set to data code 19, the maximum operating frequency will
be limited by the following values.
For all models except the WFC4075-0: For the WFC4075-0 only:
83-PWM data code 1 (3kHz) ---- 62 Hz max. 83-PWM data code 1 (2.3 kHz) ---- 48 Hz max.
83-PWM data code 2 (4kHz) ---- 83 Hz max. 83-PWM data code 2 (2.5 kHz) ---- 52 Hz max.
83-PWM data code 3 (6kHz) ---- 125 Hz max. 83-PWM data code 3 (4.6 kHz) ---- 95 Hz max.
83-PWM data code 4 (8kHz) ---- 166 Hz max. 83-PWM data code 4 (5 kHz) ---- 104 Hz max.
83-PWM data code 5 (12kHz) ---- 250 Hz max. 83-PWM data code 5 (9.2 kHz) ---- 191 Hz max.
83-PWM data code 6 (16kHz) ---- 332 Hz max. 83-PWM data code 6 (10 kHz) ---- 208 Hz max.
