Common I/O Programming Changes
Your application needs can require changing parameters from their factory
default settings.
Speed Reference A
Change Speed Reference A from Analog In 2 to Analog In 1 to connect an
external potentiometer.
1. Set Parameter 090 [Speed Ref A Sel] to option 1, Analog In 1.
Sets the speed reference input to I/O terminals 14 and 15 for voltage, and
I/O terminals 16 and 17 for current.
2. Set Parameter 096 [TB Man Ref Sel] to option 9, MOP Level.
Eliminates a potential conflict alarm condition. Analog In 2 is not a valid
Speed Reference source if selected for any of the following parameters:
• 117 [Trim In Select]
• 126 [PI Reference Sel]
• 128 [PI Feedback Sel]
• 147 [Current Lmt Sel]
3. Set Parameter 091 [Speed Ref A Hi] to the upper value of the desired
speed reference range in Hz.
4. Set Parameter 092 [Speed Ref A Lo] to the lower value of the desired
speed reference range in Hz.
Speed Reference A is now configured for an external potentiometer.
