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 Param. 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 Param. 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 Param. 091 [Speed Ref A Hi] to the upper value of the desired speed
reference range in Hz
4. Set Param. 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 Param. 361 [Digital In1 Sel] to option 7 “Run” or 9 “Run Reverse”
2. Set Param. 362 [Digital In2 Sel] to another option such as 8 “Run
Forward” or 10 “Jog”
