INSULATION DETERIORATION DETECTION FUNCTION
The α+ servo amplifier for the 30+-B series includes an insulation deterioration detection function, which can
detect a sign of insulation deterioration in motor windings and power wires automatically and accurately.
This function can use the voltage charged in the servo amplifier DC link to measure automatically the insulation
resistance between the motor or power cable and a ground immediately after the servo amplifier has shifted from a
servo-on state to an emergency stop state, thereby checking for insulation deterioration.
If an insulation resistance of 10 Mȍ or below is detected, a warning is issued.
3.2.1
How to Use
(1) To use the insulation deterioration detection function, set the parameters
listed below.
Parameter No.
Enabling/disabling the function (axis by axis)
Servo amplifier
No2429#0
0: Disable for SV (default)/1: Enable for SV
Spindle amplifier
No4549#0
0: Disable for SP (default)/1: Enable for SP
(2) Measuring the insulation resistance requires charging the DC link voltage.
So, keep the amplifier released from an emergency stop for at least 5
seconds before measurement. This is unnecessary when the machine is
working normally before measurement.
(3) The measurement of insulation resistance start by inputting the emergency
stop(*ESP) to connector CX4 of common power supply (PS) after the DC
link voltage is charged.
3.2.2
How to Check
(1) If insulation deterioration is detected, “LKG” in the lower section of the
CNC screen blinks.
(2) Measurement results can be viewed on the “LEAKAGE DETECTION
MONITOR” screen of the CNC.
3.2.3
Action
If insulation deterioration is detected, measure the insulation resistance of motor and power cables separately with
a megohmmeter to see which has a deteriorated insulation, the motor or power cable.
Then, replace the motor or power cable whichever is relevant.

3.2.4
Other Notes
(1) No insulation resistance is measured in the following cases:
- The servo amplifier enters an emergency stop state again before entering a
ready state.
- The servo amplifier is released from an emergency stop state during
insulation deterioration checks.
(2) Continuing a long-term operation with insulation deteriorated may cause
the machine to stop because of the ground fault interrupter tripping or an
alarm occurring. If insulation deterioration is detected, replace the relevant
motor or power cable as soon as possible.
(3) No accurate measurement can be made while the motor is running. So, no
measurement will be made even in an emergency stop state, for example, if
the spindle motor is rotating through inertia.
WARNING
Insulation resistance measurement starts when the emergency stop signal (*ESP) applied to the
connector CX4 of the common power supply (PS) represents an emergency stop state. During
insulation resistance measurement, the voltage charged in the DC link is applied to the motor.
Do not touch the motor during measurement to avoid getting electrical shocks. Insulation
resistance measurement begins 6 seconds after the emergency stop state has been entered.

How to replace the battery for the absolute Pulsecorder
3.3.1
Outline
・ When the voltage of the batteries for absolute Pulsecoders becomes low, alarm 307 or 306 occurs, with the
following indication in the CNC state display at the bottom of the CNC screen.
Alarm 307 (alarm indicating the voltage of the battery becomes low) :
The indication "APC" blinks in reversed display.
Alarm 306 (battery zero alarm) :
The indication "ALM" blinks in reversed display.
・ When alarm 307 (alarm indicating the voltage of the battery becomes low) occurs, replace the battery as soon as
possible. In general, the battery should be replaced within one or two weeks,however, this depends on the
number of Pulsecoders used.
・ When alarm 306 (battery zero alarm) occurs, Pulsecoders are reset to the initial state, in which absolute positions
are not held. Alarm 300 (reference position return request alarm) also occurs, indicating that reference position
return is required.
・ In general, replace the batteries periodically within the service life listed below.
- A06B-6050-K061 or D-size alkaline dry cells (LR20) : Two years (for each six-axis configuration)
- A06B-6073-K001 : Two years (for each three-axis configuration)
- A06B-6114-K504 : One year (for each three-axis configuration)
NOTE
The above values indicate the estimated service life of batteries used with FANUC absolute
Pulsecoders. The actual battery service life depends on the machine configuration based on, for
example, detector types. For details, contact the machine tool builder.
3.3.2
Replacing procedure of the battery
To prevent absolute position information in absolute Pulsecoders from being lost, turn on the machine power
before replacing the battery. The replacement procedure is described below.
<1> Ensure that the power to the servo amplifier is turned on.
<2> Ensure that the machine is in the emergency stop state (the motor is inactive).
<3> Ensure that the DC link charge LED of the servo amplifier is off.
<4> Detach the old batteries and attach new ones.

WARNING
・ The absolute Pulsecoder of each of the α+F,α +S series servo motors and the ββ+S series
servo motors (β+S0.4 to β+S22) has a built-in backup capacitor. Therefore, even when the
power to the servo amplifier is off and the batteries are replaced, reference position return is
not required if the replacement completes within less than 10 minutes. Turn the power on and
replace thebatteries if the replacement will take 10 minutes or more.
・ To prevent electric shock, be careful not to touch metal parts in the power magnetics cabinet
when replacing the batteries.
・ Because the servo amplifier uses a large-capacitance electrolytic capacitor internally, the servo
amplifier remains charged for a while even after the power is turned off. Before touching the
servo amplifier for maintenance or other purposes, ensure your safety by measuring the
residual voltage in the DC link with a tester and confirming that the charge indication LED (red)
is off.
・Be sure to replace the batteries with specified ones. Pay attention to the battery polarity. If a
wrong type of battery is used or a battery is installed with incorrect polarity, the battery may
overheat, blow out, or catch fire, or the absolute position information in the absolute
Pulsecoders may be lost.
・ Ensure that the battery connector is inserted in the correct position.
3.3.3
How to insert batteries into the battery case
Use the following procedure to replace the batteries in the battery case.
<1> Loosen the screws on the battery case and detach the cover.
<2> Replace the batteries in the case (pay attention to the polarity).
<3> Attach the cover to the battery case.

CUATION
・ Since a battery is not a commercial item, please be sure to purchase it from Fanuc. Therefore,
Fanuc recommend preparation of the spare battery.
・ When using the built-in batteries, do not connect them to the BATL (B3) of connector
CXA2A/CXA2B. The output voltages from different SV batteries may be short-circuited, resulting
in the batteries becoming very hot.
・ If it is attached where a battery cable is stretched, loose connection etc. may occur.
・ When +6V of CX 5X and 0V short-circuit, it becomes the cause of generation of heat of the
battery, a burst, ignition, and the absolute position information disappearance in an absolute
pulse coder.
・ In case you insert a connector, please insert horizontally to the direction of the pin of the
connector.

4.2.
HOW TO REPLACE FUSES ON PRINTED-CIRCUIT BOARDS
In theαi series, a printed-circuit board can be removed and inserted from the front of the servo amplifier.
The printed-circuit board removal/insertion procedure is common to the PS, SV, and SP.
Note
1. When the fuse is blowed, the cause by the power supply short circuit of other apparatus
(sensor etc.) connected to servo amplifier can be considered.
Please exchange the fuse after a check whether other apparatus is normal.
If the cause is not removed, there is a possibility that the fuse will be blowed again.
2. Please use the fuse supplied from FANUC.
3. Please check the rating mark on the PCB and seal of the fuse to prevent mistakes.
4. Reverse connection of 0V and 24V of the connector(CXA2D) for the external DC24V or the
connector(CXA2A/B) for the communication between amplifiers make the fuse blow.
[Countermeasure]
1.Replace the fuse.
2.Change to the correct connection.
Pull the PCB
toward front side
Hold the upper and
Lower hooks
PCB
To insert the printed-circuit board, reverse the above procedure.
Ensure that the upper and lower hooks snap into the housing.
If the printed-circuit board is not inserted completely, the housing
remains lifted. Pull out the printed-circuit board and insert it again.
