Analog Input Option Card
AI-14B
Figure 2. Voltage/Current Selection Jumpers
Part Number: AI-14B.
Applicability: F7, G7, GPD515/G5, G5 HHP.
Note: If used in a GPD503/G3 or VCD703/VG3, refer to
Instruction Sheet 02Y00025-0296.
Introduction: The AI-14B analog input option board is
mounted on the drive’s control board and enables the user to
interface three separate high-resolution analog input signals,
each of which may be either voltage or current (13-bit + 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. The polarity (sign) of the analog input can be
used to control items such as motor direction and torque
direction.
Receiving: All equipment is tested against defect at the
factory. Report any damages or shortages evident when the
equipment is received to the commercial carrier who
transported the equipment.
Warning: Hazardous voltage can cause severe injury or
death. Lock all power sources feeding the drive in the “OFF”
position.
Caution: This option card uses CMOS IC chips. Use proper
electrostatic discharge (ESD) protective procedures when handling the card to prevent I.C. damage or erratic drive operation.
Important:
1. If this option is being installed in a drive with an encoder (PG) feedback option card, that card will need to be temporarily
removed to allow access to connector 2CN on the drive’s control board and TC1 – TC4 on the AI-14B option card.
2. Before installing this option, a technically qualified individual, who is familiar with this type of equipment and the hazards
involved, should read this entire installation guide.
Installation and Wiring:
1. Disconnect all electrical power to the drive.
2. Remove the drive’s front cover.
3. Check that the “CHARGE” indicator lamp inside the
drive is off.
4. Use a voltmeter to verify that the voltage at the
incoming power terminals (L1, L2, L3) has been
disconnected.
5. Option Card Installation: See Figure 1. Position the option
card above the control board’s 2CN connector and gently
press the card into place.
6. Wiring: Refer to Figure 3 and Tables 1 & 2. Make wire
connections between the AI-14B card and the drive as well
as all peripheral devices. Observe the following:
a) Determine whether a voltage or current signal will be
used for each of the channels of the AI-14B board. Set
selection jumpers accordingly. See Figure 2.
b) Keep the AI-14B (i.e. control circuit) wiring separate
from main circuit input/output wiring. A separate
metallic grounded conduit with only the option card’s
wiring running through it is preferred.
c) To prevent erroneous operation caused by noise
interference, use shielded cable for control signal wiring.
Limit the distance to 10m (33 feet) or less.
