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
800
[Anlg ln1 Data] (the source)
•
Select Ref 1 as the active speed ref
Par 16
[Speed Ref Sel] = 1
•
Par 153
[Control Option]\bit 0 = 0 (Unipolar Speed
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
Analog Outputs
- +/
-10V DC
Used to drive analog
meters displaying speed
and current
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
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

Connection Example
Primary Encoder
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
Primary Encoder - using internal power supply
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
