Rockwell Automation 1397 DC Drive Firmware 2.xx - Manual (Page 16)

1–8 Introduction
Publication 1397-5.0 — June, 2001
The three customer analog inputs are Analog Reference 1, Analog
Reference 2 and Analog Tachometer Feedback. These inputs are
converted within the Drive to 12 bits plus sign at their full range.
The electrical specifications for each of these are listed below.
Analog Reference 1 (Terminals 19,20)
(see page 4.25 for J10 & J12 jumper settings)
Voltage Reference +10 V DC
Milliamp Reference 4-20 mA or 10-50 mA
Analog Reference 2 (Terminals 16, 17, 18)
(see page 4.24 for J19 jumper settings)
Potentiometer 5k
Ω minimum
External Voltage Source +10 V DC
0 to 10 Volts DC
Analog Tachometer Feedback
(see page 4.20 for J11 and J14 jumper settings)
Tach Voltage at Top speed 10 to 250 V DC
The two metering analog outputs are available at regulator board
terminals 24, 25 and 26. Terminal 25 is the common connection for
both output signals. The selected signals for both meter outputs are
averaged (filtered) over 100 ms to reduce meter fluctuations.
NOTE: Refer to the Start-Up chapter for information on
programming Analog Outputs.
