Yaskawa AI-040 User Manual

Isolated Analog Input Option Card

Part Number: AI-040 Kit (UTC000015 Card) (formerly AI-14B2). Applicability: F7, G7, GPD515/G5.

Note: If used in a GPD503/G3, refer to Instruction Sheet 02Y00025-0431.

Introduction: The AI-040 isolated analog input option board is mounted on the drive’s control board and enables the user to employ precision isolated analog signals to interface three separate high resolution analog input signals, each of which may be either current or voltage (13-bit + sign). These signals are isolated from ground and the drive, but NOT from each other. 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-040 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-040 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-040 card. Set selection jumpers accordingly. See Figure 2.

b) Keep the AI-040 (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.

d) If any of the control signal input terminals (TC1-TC3) are NOT used, jumper them to 0V Terminal (TC4). e) Route wires from the drive and connect to the peripheral device. Refer to the drive technical manual for further

information on use of shielded cable.

f) Connect the option card ground wire (G1) to the drive’s ground terminal TB3 (12 for G5). Important: Because the analog input is high-resolution, the voltage source accuracy of the analog input must be

considered. To ensure accuracy, use a high-precision power supply for the voltage source.

7. Adjustment. There are no adjustments to be made on the AI-040 option; however, the drive will have to be programmed for the input requirement(s) of the remote device and the reversing or non-reversing requirement of the specific application. Refer to Figures 4 and 5, and Table 3.

8. Reinstall and secure the drive’s front cover.

9. Place this instruction sheet with the drive’s technical manual.
