Detailed Drive Operation Chapter 1
Using Digital Inputs and the Selector Switches to Configure Preset Speeds:
The digital inputs can be used to configure up to 16 preset speeds using the
Selector Switches function.
Example Digital Input and Selector Switch Configuration:
In this example, three digital inputs are used to control the status of bits 1 “Sel
Swtch 00”…3 “Sel Swtch 02” of parameter 1022 [Sel Switch Ctrl] to then select
one of eight preset speeds configured in parameters 1029…1036. The binary
coded decimal (BCD) output of bits 1 “Sel Swtch 00”…3 “Sel Swtch 02” of
parameter 1022 are or’d together to select the desired parameter and preset speed.
• Set parameter 826 [Dig In2 Sel] to 34 “UserGen Sel0”. When digital input
2 is energized, bit 1 “Sel Swtch 00” of parameter 1022 is set high.
• Set parameter 827 [Dig In3 Sel] to 35 “UserGen Sel1”. When digital input
3 is energized, bit 2 “Sel Swtch 01” of parameter 1022 is set high.
• Set parameter 828 [Dig In4 Sel] to 36 “UserGen Sel2”. When digital input
2 is energized, bit 3 “Sel Swtch 02” of parameter 1022 is set high.
• Set bit 1 “Sel Switches” of Par 1000 [UserFunct Enable] to “1” (enables the
Selector Switch user function).
• Set bit 0 “SSW DataPass” of Par 1022 [Sel Switch Ctrl] to “1” (enables the
passing of the data from the selected parameter to Par 1045 [SelSwtch
RealOut] and 1046 [SelSwtch DIntOut]).

control that selects
1 of 16 inputs (Pars
1029 – 1044 ) that
provides output to
Par 1045 or Par
1046 . BCD values
of bits 01 – 04 of
Par 1022 are or’d
together to select a
switch. Bit 01 of
1022 is the LSB. A
binary value of
“0000 ” selects Par

value of “1111 "
selects Par 1044 .
