Hardware Description
125 – 300 HP, 230VAC 250 – 600 HP, 460VAC
4-21
The inputs are preconfigured for the following signals: RUN
REFERENCE SELECT A,B,C, RAMP DISABLE, JOG 2, JOG1,
NORMAL STOP, START, CLOSE CONTACTOR, CLEAR FAULT.
Digital Outputs – Five programmable solid state outputs are provided.
These 24VDC outputs, can be connected to any source parameter such as
the logic status word. All five outputs are LED indicated for high input
level visibility.
These outputs are preconfigured for the following signals: ZERO SPEED,
DRIVE RUNNING, READY, AT CURRENT LIMIT, AT SET SPEED.
Analog Inputs – Two programmable analog inputs allow a +/– 10 volt
signal through a 12 bit A to D converter, thus providing 4.88 millivolts per
bit resolution.
The inputs are preconfigured for the following signals: VELOCITY
REFERENCE, TACH VELOCITY.
Analog Outputs – Two programmable analog outputs allow a +/– 1024
Drive signal to be converted to a +/– 10VDC analog output through a 12
bit digital to analog converter, thus giving 9.76 millivolts per bit resolution.
Through programming of associated Scale and Offset parameters the
effective range of the Drive signal can be extended to +/– 32767. The
digital Drive signal can be any of the 1395 run-time parameters.
The outputs are preconfigured for the following signals, VELOCITY
FEEDBACK, ARMATURE CURRENT FEEDBACK.
All user connections to the board are made at Terminal Block TB3 located
at the bottom of the 1395 Drive.
All inputs and outputs have the flexibility of being reconfigured by the
user for other signals.

the Digital Reference Adapter Manual.
Node Adapter Board The Node Adapter Board provides an interface between external devices
and the Main Control Board of the Bulletin 1395. The board allows the
1395 to be controlled using an Allen-Bradley PLC Controller from either
the PLC3

or PLC5

family.
For a more detailed description of the Node Adapter, refer to the Node
Adapter Manual.
Multi-Communication Board The Multi-Communication Adapter Board provides a sophisticated
interface to Allen-Bradley PLC controllers and other equipment capable of
communicating over serial communications links.
The Multi-Communication Adapter is not preconfigured. Refer to the
Multi-Communication Board Software/Hardware Reference Manual, for
hardware and integration information.
