Rockwell Automation LPM20 Liquid-Cooled AC Drive with High Performance Drive Control - Manual (Page 39)

Installation/Wiring 1-27
Analog Output
+/- 10V dc
Used to drive analog meters
displaying speed and current.
0-10V Analog Output Required Parameter Changes
Using Analog Output 1 (-10V to +10V) to meter
Motor RPM and direction:
• Send the data to the Analog Output Parameter
833 [Anlg Out1 Real], the destination, linked to
Parameter 71 [Filtered SpdFdbk], the source.
• Scale the Output to the source parameter.
Example: Parameter 835 [Anlg Out1 Scale] =
175 (where Parameter 4 [Motor NP RPM] 1750
is divided by 10V output).
Using Analog Output 2 (-10V to +10V) to meter
Motor current:
• Send the data to the Analog Output Parameter
840 [Anlg Out2 Real], the destination, linked to
Parameter 308 [Output Current], the source.
• Scale the Output to the source parameter.
Example: Parameter 822 [Anlg Out2 Scale] = xx
(where Parameter 2 [Motor NP FLA] is divided
by 10V output).
Primary Encoder Interface -
Supports 5V dc/12 V dc
differential encoders with
internal power supply. Primary Encoder - Internal Supply Using Encoder 0 as speed feedback:
• Set Parameter 222 [Motor Fdbk Sel Pri] to a
value of 0 (Encoder 0 = default), so the drive will
use this encoder as the primary motor speed
feedback device.
• Set the value of Parameter 232 [Encoder 0
PPR] to match the installed encoder’s resolution
(Pulses per Revolution).
