Analog I/O Connection Example
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

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 (Par 4 [Motor NP
RPM] = 1750 / 10V)
Output #2
Using Analog Out 2, -10V to + 10V to meter Motor
Motor
Current:
Current
• Send the data to the Analog Output
Par 820 [Anlg Out2 Real] (the destination) linked to
Par 308 [Output Current] (the source)
• Scale the Output to the source parameter
Par 822 [Anlg Out2 Scale] = xx (Par 2 [Motor NP
FLA] / 10 V Output)
Required Parameter Changes
Using Encoder 0 as speed feedback:
• Par 222 [Motor Fdkbk Sel] = 0 "Encoder 0" (default)
• Par 232 [Encoder0 PPR] = Pulses/Rev for installed
