(5) Control power supply
In the event of a power failure, supplies power to the control power supply inputs of
the amplifier and the CNC.
A06B-6077-H002 (200V input type)
Supplies power from connector CX13 to the control power supply inputs of the
amplifier and the CNC.
In normal operation, the200 VAC input to connector CX12 is output to connector
CX13.
In the event of a power failure, DC link voltage is output from connector CX13.
A06B-6091-H002 (400V input type)
Supplies power from connector CX28 to the control power supply inputs of the
amplifier and the CNC.
In normal operation, the200 VAC input to connector CX27 is output to connector
CX28.
In the event of a power failure, 300 VDC (voltage resulting from stepping down
the DC link voltage) is output from connector CX28.
Power supply capability of connectors CX13 and CX28
1000 VA maximum (including up to 300 VA to be supplied to the PSM control power supply)
Power switching time
After a power failure, when the output of connector CX13 or CX28 switches from200
VAC to direct-current voltage, an instantaneous break of up to 30 msec occurs (state
in which the output of connector CX13 and CX28 becomes 0 V).
To connector CX13 or CX28, connect a device that permits an instantaneous break of
30 msec.
Calculation of the power capacity
If the power capacity of the device to be connected to connector CX13 or CX28 is
indicated in units other than VA, determine the power capacity with the method
described below.
If power consumption is indicated in watts
Divide the consumption by the power factor, and you will get the power capacity. If the
power factor is unknown, assume the power factor to be 0.5.
If current consumption is indicated in amperes
Multiply the consumption by the working voltage of 200V, and you will get the power
capacity.

Power Failure Backup Module
Descriptions
A-53866E-464
For a switching power supply whose output current is known
Power capacity (VA) = Output voltage (V) x Output current (A)
÷ Power supply efficiency ÷ Power factor
If the efficiency and the power factor of the power supply
are not known, assume the
efficiency to be 0.85 and the power factor to be 0.5.
Measure to be taken if the power capacity of the device to be connected to connector CX13 or
CX28 exceeds 1000 VA
If the power capacity of the device to be connected to connector CX13 or CX28 exceeds 1000
VA, supply power from a UPS (uninterruptible power supply) to the device.
Even if you use a UPS, make sure that the control power to the PSM is supplied from the power
failure backup module (the control power supply input connector CX1A of the PSM is
connected to CX13 or CX28).
Backup of the control power to the dynamic brake module (DBM)
The dynamic brake module is driven on 200 VAC, and cannot be driven on direct current.
A system using a dynamic brake module requires a UPS with an output of 200 VAC for
the dynamic brake module. For connection information, see (18) in Section 5.2.
Specifications of the switching power supply to be connected to connector CX13 or CX28
<1> Input voltage range
170 VAC to 264 VAC (continuous)
240 VDC to 373 VDC (in power failure backup operation, 1 min. max.)
* Some types of switching power supply cannot be driven continuously on DC power
and, therefore, the specifications of some of these types state that they "cannot
be driven on DC power". Even such types can be driven on DC power if they satisfy
the time requirement for power failure backup (1 min. max.).
<2> Output current
Depends on the current consumption of the device to be connected.
<3> Operation at and below the input voltage specifications
The state in which the input voltage is 0 VDC to 240 VDC may keep for a maximum
of one minute. Even in this case, the switching power supply must be free from
damage and no voltage exceeding the specification range tolerable by the CNC and
others (24V+10%) may be output.

<4> Retention time at an instantaneous power break
30 msec or greater
* Generally, the retention time given on the catalog is the value assumed when
the load factor is 100%. If the retention time requirement of 30 msec or greater
is not satisfied, the retention time can be extended by reducing the
load factor.
An example of a power supply that conforms to the above specifications is the LDA150B-24 of
COSEL Co., Ltd. (output: 150W).
(8) I/O input/output specifications
Rules for the control signals (EXPFL and *SYNC) for the power failure backup module and
the state signals (RDY, *PFL, and *ALM) output from the power failure backup module are
as follows:
Input signal rules
Pin 3 (EXPFL) of connector CX15 and pin A3 (*SYNC) of connector CX16
Contact capacity 24 VDC+10% 10mA
Voltage drop across contacts
at closed circuit
2 V or less (including a cable voltage drop)
Output signal rules
Pin B1 (*ALM), pin B2 (*PFL), and pin B3 (RDY) of connector CX16
ON-time maximum load current 200 mA or less including an instantaneous current
ON-time saturation voltage 1 V or less (at load current of 200 mA)
Withstand voltage 24 V+20% including an instantaneous voltage
OFF-time leak current 20 µA or less
Delay time 50 µsec
Protection function If the load current increases abnormally due to
the grounding of a cable or other reasons, the
protection function will operate and keep all
outputs OFF until the cause is removed.
For details of each signal, see Sections 6.5 and 6.6.
For details of the connection of connectors CX15 and CX16, see (6) and (7) of Section
5.2.
CAUTION
At a power failure, DC voltage is output from CX13 or CX28, instead of 200 VAC.
Never connect a device containing an AC fan motor or AC-driven electromagnetic
contactor to CX13 or CX28 because such a device may be burned out if DC voltage

(7) Alarm handling
If an error occurs in the power failure backup module, the alarm number corresponding
to the error is indicated on the LED and connector CX16 outputs *ALM of 0.
Even if an alarm is generated, the power failure backup module does not forcibly
shut off power, so that the machine continues normal operation. If, however, an alarm
is generated in the power failure backup module, it will no longer perform power failure
backup operation in the event of a power failure. For this reason, if the power failure
backup module outputs *ALM of 0, immediately perform processing that stops the machine.
Also, shut off the PSM input, MCC, to protect the power failure backup module as soon
as you stop the machine.
For a description of alarms and their causes, see Section 6.4.
If, during machine operation, RDY changes from 1 to 0 although the power failure
backup module does not output an alarm signal (*ALM=1), this indicates that an error
has occurred in the power failure backup module.
If, during machine operation, RDY changes from 1 to 0, take the same action as that
when an alarm is generated in the power failure backup module.
(8) Total heat dissipation
Power failure backup module
A06B-6077-H002: 12W
A06B-6091-H002: 25W
Sub module C
A06B-6077-H010: 5W
A06B-6083-H245: 4W
Sub module R: No heat dissipated in the stationary state
(9) Environmental conditions
The environmental conditions for the αi series amplifier apply.
