Common I/O Programming Changes

Your application needs may 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”
This sets the speed reference input to I/O terminals 1 & 2. For 4…20 mA
operation, a jumper must be placed between terminals 17 & 18.

2.

Set Parameter 096 [TB Man Ref Sel] to option 9 “MOP Level”
This eliminates a potential Conflict alarm condition. Analog In 2 is not a
valid Speed Reference source if selected for any of the following:

117 [Trim In Select]

126 [PI Reference Sel]

128 [PI Feedback Sel]

147 [Current Lmt Sel]

179 [Sleep-Wake Ref ]

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

Control Scheme

Change from 3 Wire Start/Stop to 2 Wire Run/Not Run at Digital In 1 &
Digital In 2.

1.

Set Parameter 361 [Digital In1 Sel] to option 7 “Run” or 9 “Run Reverse”

2.

Set Parameter 362 [Digital In2 Sel] to another option such as 8 “Run
Forward” or 10 “Jog”
