WARNING

PRECAUTIONS

1. Read this instruction manual in its entirety before installing the Isolated Monitor Card AO-12B2 or

operating the inverter with this card installed.

2. DO NOT connect or disconnect wiring, or perform signal checks while the electrical power is turned ON.

Failure to observe these and other precautions indicated in this manual will expose the user to high
voltages, resulting in serious injury or death. Damage to equipment may also occur.

!

CAUTION

NOTE

The Option Card uses CMOS IC chips. Therefore, the card could become damaged when physically
handled if static electricity is present. The person handling the card should wear a discharge strap to
eliminate the possibility of static charge (if present) affecting the card.

Failure to observe this precaution may result in equipment damage.

INTRODUCTION

The Isolated Analog Card AO-12B2 mounts to an inverter’s control board via connection to option port
3CN, and is used to output dual analog signals for monitoring the inverter’s status: output frequency, out­put current, etc. The signal level is jumper selectable for -10 to +10 VDC, 0-20mA, or 4-20mA ranges.

The channels are isolated from the inverter, but not from each other.

INSTALLATION

1. Before attempting to install or use the Isolated Analog Monitor Card AO-12B2, read the follow­ing instructions.

2. After unpacking the card, verify that you have received the correct code number and that no dam­age had occurred during shipping. Contact your YASKAWA representative should you require
any assistance.

3. Turn OFF the main electrical power to the inverter, and allow sufficient time (usually 5 minutes)
for the DC bus to decay to less than 50V DC. The DC bus voltage can be measured by removing
the terminal strip cover, and then using the B1/ and terminals located on the main terminal
strip.

4. Remove the inverter’s cover by first removing the digital operator.

a) For smaller inverters, push inward (on the cover) at the indented area located near the bot-

b) Larger inverters have screws to hold their covers in place that must be removed.

tom on each side of the cover. While lifting the cover, pivot the cover’s bottom upward.

(Refer to the VS-616/ VS-676 Series User’s Manual, if necessary).

5. Check that the indicator CHARGE lamp is OFF (power OFF indication).

6. Place the Monitor Card onto the standoff post in the Control Board, aligning the Monitor Card’s
connector with the Control Board’s 3CN connector. Refer to Fig. 1 Location of Isolated Analog
Monitor Card AO-12B2.

7. Gently, push the Monitor Card downward onto the standoff post until it protrudes through the
card’s mounting hole, while aligning and connecting the card’s female connector to the control
board’s 3CN male connector.

8. Connect the Monitor Card’ s grounding cable (green wire) to the control board’ s T erminal No.12
(G) ground terminal screw.

CAUTION

WIRING NOTES

1. Separate the output signal wires that are connected to the Isolated Analog Monitor Card’s terminal
block (TB1) from the main circuit wires and other power cables.

2. Use a twisted pair-shielded wire to connect output signals. Connect the shield as shown in Fig. 3 to
prevent noise interference.

Shield

A. NEVER connect the wire’s shield to signal wires.
B. CONNECT the wire’s shield (at the inverter side only) to terminal TB1-3.
C. WRAP insulating tape around exposed shielded, sheathed areas and wires where termination occurs.

3. Care must be taken in the selection of the twisted shielded wire over 50 feet long. The impedance of
the wire should be sufficiently low to insure signal amplitude for proper operation of all equipment
connected to the Isolated Analog Monitor Card AO-12B. In general, as the wire’ s length is increased,
it’s cross section or gauge must also increase.

4. The National Electrical Code (NEC) and any applicable regional or local codes should be observed
when wiring electrical devices.

Wiring Connection Notes:

1. To prevent noise, use shielded wire as specified in Fig.4.

2. Separate the power wiring circuits (200VAC or greater) and relay wiring circuits (120VAC) from the
control wires.

3. Wire lengths must be 164 feet (50 meters) or shorter.

4. Connect the AO-12B2 grounding lead wire (E) to the inverter control board’s grounding terminal 12.

5. Applicable wire sizes for terminal block TBI are as listed in the following table.

1. Cable too heavy exerts pressure on the Option Card and could cause failure.

2. Cable too thin could cause a poor connection or prematurely break or overheat.

Programming Example:

Program a G5 inverter to output a signal on Channel 2 of the AO-12B2

Option Card proportional to output current. The desired signal level is
10 volts at 200% of inverter rated output current.

Step 1. Verify that the option card is properly installed and wired.

Step 2. Jumper Settings:

Channel 2 as output voltage -10 to +10 VDC
HDR1 Jumpers in position 2 to 4 and 1 to 3
HDR3 Jumpers in position 4 to 6 and 1 to 3
Refer to Pages 9 and 10 for further details.

Step 3. Program Channel 2 to desired signal.

Output current = > F4-03=03
Refer to Table 9 on Page 14.

Step 4. Program desired signal amplitude.

If voltage desired is 10V @ 200% current,
this means 5V @ 100% current.

So, 10V

X Setting Value = 5V

100%

Thus, a setting value of 50% or 0.50 is necessary, F4-04 = 0.50

Step 5. Verify operation.
