ANALOG SPEED REFERENCE

(BIPOLAR) (AI-14B) MODEL DS387

Section A: Installation in a GPD 515

INTRODUCTION
When installed, this option allows the user to interface three separate high resolution analog input signals, each of

which may be either current or voltage (13-bit plus sign). These signals can act as a direct replacement for the
three existing analog inputs available on the drive (3-channel individual mode), or the signals can be added together
and used as a single frequency reference (3-channel addition mode). Gain and Bias are adjustable for both modes
using drive parameters. Polarity (sign) of the speed reference controls direction of motor rotation.

INSTALLATION
A1. Disconnect all electrical power to drive.

A2. Remove drive front cover. Check that CHARGE indicator lamp inside drive is off.
A3. Verify voltage has been disconnected by using a voltmeter to check for voltage at incoming power terminals

(L1, L2, L3).

NOTE: If this option is being installed in a GPD 515 with speed feedback, the speed feedback card needs to
be temporarily un-installed to allow access to the connector 2CN on the Drive’s Control Board and TC1-TC4
on the AI-14B option card.

A4. See Figure A1. Install the option on the Main Control Board, 1PCB, and ensure 2CN is properly connected.
Make sure Electrostatic procedure is followed.

Figure A4. AI-14B Block Diagram

As Figure A4 shows, there are two possible modes of operation for the AI-14B board when it is installed in the
GPD 515. These modes are selected by drive parameter F2-01 (AI-14B Input Selection). When F2-01 is set to
" 0 ", 3-channel individual mode is selected. In this mode the AI-14B replaces the analog inputs on the GPD 515
main control board (see Table A3). When F2-01 is set to " 1 ", 3-channel addition mode is selected. In this mode
the AI-14B adds the three channels together. This new “added” signal replaces the automatic speed reference
input (terminal 13) when reference source is set to "Option PCB" ( b1-01 = 3).

INTRODUCTION
When installed, this option allows the user to interface three separate high resolution analog input signals, each of

is adjusted by using drive constants. Polarity (sign) of the speed reference controls direction of motor rotation.

C2. Remove drive front cover. Check that CHARGE indicator lamp inside drive is off.
C3. Verify voltage has been disconnected by using a voltmeter to check for voltage at incoming power terminals

(L1, L2, L3).
