Yaskawa AI-14B User Manual

Analog Input Option Card

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.

d) If any of the control signal input terminals (TC1-TC3) are NOT used, jumper them to the 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) 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-14B option; however, the drive will have to be programmed for the input requirements of the peripheral 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.
