Rockwell Automation SP600 AC Drive User Manual Version 1.0 - Manual (Page 211)

Parameter Descriptions 12-81
The drive scales the value read from the analog input and converts
it to scaled units for the drive. The user controls the scaling by
setting parameters that associate a low and high point in the input
range with a low and high point in the target range.
Analog In 1 Hi sets the highest input value to the analog input 1
scaling block. See figure 12.51.
322 Analog In 1 Hi
Range: 4.000 to 20.000 mA [0.001 mA]
+/-10.000 VDC [0.001 V]
0.000 to 10.000 V [0.001 V]
Default: 20.000 mA

Analog Input Scaling Example
Assume:
• Speed Ref A Sel = Analog In 1
• Ref Lo (92) = 10 Hz
• Ref Hi (91) = 60 Hz
• Analog In 1 Lo (323) = 0.0 V
• Analog In 1 Hi (322) = 10.0 V
• Analog In Config (320) = xxxx...xx00
