Rockwell Automation 1397 DC Drive Firmware 2.xx - Manual (Page 48)

2–30 Installation
Publication 1397-5.0 — June, 2001
The Bulletin 1397 is supplied with the following standard I/O
compliment:
• 10 Digital Inputs
24V DC internally or externally supplied
8V DC turn–on voltage
0.5 mA turn–off current
• 3 Contact Outputs
250V AC maximum
30V DC maximum
2A maximum resistive load
1A maximum inductive load
• 2 Speed Reference Inputs
Analog Reference 1
±10V DC
4 – 20 mA
10 – 50 mA
Converted within Drive to 12 bit plus sign
Analog Reference 2
External potentiometer (5k
Ω min.)
±10V DC
Converted within Drive to 12 bit plus sign
• DC Tachometer Input
10 – 250V DC
Converted within Drive to 12 bit plus sign
• 2 Analog Outputs
±10V DC
4A maximum load
In order to maintain simplicity, the functions of the analog and
digital inputs are fixed. The analog and digital outputs, however,
may be reconfigured. See Chapter 5 for information on parameters
that must be manipulated to reconfigure the outputs.
ATTENTION: The 1397 Drive control circuitry
includes solid–state components. If hazards due to
accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exist, an
additional hardwired stop circuit may be required to
remove AC line power to the Drive. When AC input
power is removed, there will be a loss of inherent
regenerative braking effect and the motor will coast to a
stop. An auxiliary braking method may be required.
