Analog I/O
Connection Example
Analog Inputs
Analog Inputs - shield terminated at source
- +/-10V DC or +/-1.0V
DC (DIP switch setable)
Terminate shields at the
analog source if analog
common is available
Used for Speed
Reference and Speed
Trim
Analog Outputs - +/
-10V DC
Used to drive analog
meters displaying speed
and current
Input/Output
Connection Example
Primary Encoder
Primary Encoder - using internal power supply
Interface -
Supports 12V DC
differential encoders with
internal power supply.
5V DC differential
encoders require
external power supply
and special jumper
settings.
Used as primary closed
loop speed feedback

Required Parameter Changes
Using Analog In1 as 0 - 10 V speed reference:
•
Scale the Input to 1 V
Par 802 [Anlg ln1 Scale] =.1
•
Send the data to the Speed Reference parameter
Par 10 [Speed Ref1] (the destination) linked to Par

•
Select Ref 1 as the active speed ref
Par 16 [Speed Ref Sel] = 1

Par 153 [Control Option]\bit 0 = 0 (Unipolar Speed
Trim
Reference)
Using Analog In2 as -10 to +10V speed trim @ 10%:
•
Scale the input to .1V - 10%
Par 808 [Anlg ln2 Scale]=.01
•
Send the data to the speed Reference parameter
Par 13 [Speed Ref2] (the destination) linked to Par
806 [Anlg ln2 Data] (the source)
•
Select Ref 1 as the active speed ref and Ref2 as trim
[Speed Ref Sel] = 3
Using Analog Out 1, -10V to + 10V to meter Motor
RPM and direction:
•
Send the data to the Analog Output
Par 815 [Anlg Out1 Real] (the destination) linked to
Par 300 [Motor Spd Fdbk] (the source)
•
Scale the Output to the source parameter
Par 817 [Anlg Out1 Scale] = 175 (1750 Par 4 [Motor
NP RPM] / 10V)
Using Analog Out 2, -10V to + 10V to meter Motor

•
Send the data to the Analog Output

Required Parameter Changes
Using Encoder 0 as speed feedback:
•
Par 222 [Motor Fdkbk Sel] = 0 (Encoder 0 = default)
•
Par 232 [Encoder 0 PPR] = Pulses/Rev for installed
