For GPD 515/G5 and GPD 503
Adjustable Frequency Drives
ANALOG SPEED REFERENCE (UNIPOLAR) (AI-14U)
MODEL DS386
Before installing this option, a TECHNICALLY QUALIFIED INDIVIDUAL, who is familiar with this type of
equipment and hazards involved, should READ this ENTIRE INSTRUCTION SHEET.
IMPORTANT
This option may have been installed by the factory. However, certain steps can
only be completed at the installation site. Therefore, review and then perform
those steps which complete the installation process.
INTRODUCTION
When installed, this option allows the user to interface a high resolution (14-bit) analog speed reference to the
GPD 515/G5 or GPD 503. This reference can be either voltage (0-10V) or current (4-20mA). Frequency
command gain and bias are adjusted by programming settings in the drive.
CAUTION
The option card uses CMOS IC chips. If proper electrostatic discharge (ESD)
protective procedure is not used when handling the card, the ICs may be damaged,
resulting in erratic performance of the drive.
INSTALLATION
1. Disconnect all electrical power to drive.
2. Remove drive front cover. Check that CHARGE indicator lamp inside drive is off.
3. Verify voltage has been disconnected by using a voltmeter to check for voltage at incoming power terminals
(L1, L2, L3).
WARNING
HAZARDOUS VOLTAGE CAN CAUSE SEVERE INJURY OR
DEATH. LOCK ALL POWER SOURCES FEEDING DRIVE IN
"OFF" POSITION.
NOTE: If this option is being installed on a GPD 515/G5 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, TC2
& TC3 on the AI-14U option card.
4. See Figure 1 (GPD 515/G5) or Figure 2 (GPD 503). Install the option on the Main Control Board, 1PCB, and
ensure 2CN is properly connected. Make sure Electrostatic procedure is followed.
