A06B-6079-H206

The FANUC A06B-6079-H206 is a 2-axis servo amplifier module. Its standard dimensions are 380 x 60 x 307 mm. The Status display is a 7-segment LED that indicates the operation status on the module. If the Status display is not on then the power is not turned on, the cable has a power connection, or the module is defective. If the module is defective, replace the fuse or servo amplifier. If there is a single middle line on the display, the control power supply is waiting for the ready signal. If all the outside lines are on, the servo amplifier is ready to operate and the servo motor is supplied with power. If an alarm is issued on the servo amplifier, a value other than “0” and “-” is displayed.

A pin board can be used with the A06B-6079-H206. The use of a check pin board allows you to observe the signals inside FANUC servo amplifiers. CN1 and CN2 are wired with a one to one correspondence. The connector pin numbers correspond to the check pin numbers. You can observe an instantaneous motor current value by observing the voltage across a reference voltage check pin and a motor current check pin with an oscilloscope. Note that you cannot use a device as a multimeter to observe the correct values. You can also measure the voltage across a reference voltage (0V) check pin and a power check pin with a multimeter, oscilloscope, or the like to observe the power supply voltage fr the control circuit inside the servo amplifier. If the measured voltage is within 5% relative to the nominal voltage, the measured voltage is considered acceptable.

A special lithium battery can be installed in the A06B-6079-H206. Be sure to install the battery with correct polarity, otherwise it may overheat, blow out, or catch fire. Use the factory-installed protection sockets in the unused connector after installing. This can help prevent the battery from short-circuiting.

The Status display provides a wonderful perspective on how the product is functioning at any given time. In the case that the status display does not appear to be turned on it is likely that at least on of the following is occurring or has occurred: the power is not turned on, or the module is defective.  In the case that the module is defective, replacing the fuse or servo amplifier is a great solution to problem. Another key message to be aware of is if there is a single middle line appearing on the status display.  If this occurs, it is likely that the control power supply is waiting for the ready signal. If all the outside lines are on, the servo amplifier is ready to operate, and the servo motor is supplied with power. Last but not least, if an alarm is issued on the servo amplifier, a value other than “0” and “-” is displayed.  So, as you can, see this status display and module as a whole is a fantastic piece of equipment.

Another handy function of this A06B-6079-H206 is that a pin board can be used. The use of a check pin board allows you to observe the signals inside a FANUC servo amplifiers. CN1 and CN2 are wired with a one to one correspondence. The connector pin numbers correspond to the check pin numbers. You can observe the instantaneous motor current value by observing the voltage across a reference voltage check pin and a motor current check pin with an oscilloscope.

If the measured voltage is within 5%, relative to the nominal voltage, the measured voltage is considered acceptable. A special lithium battery can also be installed in the A06B-6079-H206. Be sure to install the battery with correct polarity, otherwise it may overheat, blow out, or catch fire. Use the factory-installed protection sockets in the unused connector after installing. This can help prevent the battery from short-circuiting.  This valuable information will be an asset to you if you are working to better understand this 2 Axis Alpha Servo Module, and any 2 Axis Alpha Servo Module in general.
