frequency, tolerable instantaneous power failure time) indicated in each specifications manual.
When making detector cables, do not mistake connection. Failure to observe this could result in
malfunction, runaway or fire.
(5) Troubleshooting
Use a motor with electromagnetic brakes or
establish an external brake mechanism for the
purpose of holding; this serves as
countermeasures for possible hazardous
situation caused by power failure or product
fault.
Use a double circuit structure for the
electromagnetic brake’s operation circuit so
that the brakes will activate even when the
external emergency stop signal is issued.
The machine could suddenly restart when the power is restored after an instantaneous power
failure, so stay away from the machine. (Design the machine so that the operator safety can be
ensured even if the machine restarts.)

To secure the absolute position, do not shut off the servo drive unit’s control power supply when its
battery voltage drops (warning 9F) in the servo drive unit side.
If the battery voltage drop warning alarm occurs in the controller side, make sure to back up the
machining programs, tool data and parameters, etc. with the input/output device before replacing the
battery.
Depending on the level of voltage drop, memory loss could have happened. In that case, reload all
the data backed up before the alarm occurrence.
(6) Maintenance, inspection and part replacement
CAUTION
(7) Disposal
Periodically back up the programs, tool data and parameters to avoid potential data loss. Also, back
up those data before maintenance and inspections.
When replacing the battery on the controller side, the machining programs, tool data and para meters
should be backed up with the input/output device beforehand.
In case the memory is damaged in replacing the batteries, reload all the data backed up before
replacing the battery.
The electrolytic capacitor’s capacity will drop due to deterioration. To prevent secondary damage
due to capacitor’s faults, Mitsubishi recommends the electrolytic capacitor to be replaced approx.
every five years even when used in a normal environment. Contact the Service Center or Service
Station for replacements.
Do not perform a megger test (insulation resistance measurement) during inspection.
Do not replace parts or devices while the power is ON.
Do not short-circuit, charge, overheat, incinerate or disassemble the battery.

3.3 Heat Radiation Countermeasures

3.3 Heat Radiation Countermeasures
Please refer to the following method for heat radiation countermeasures.
<Hypothetical conditions>
(1) Average internal temperature of operation panel: T ≤ 55°C (2) Peripheral temperature of operation panel : Ta ≤ 0°C to 45°C (3) Internal temperature rise value : ΔT = T–Ta (max) = 10°C
Example of heat radiation countermeasures
Procedures for heat design and verification

<Calculation example of heating value in operation panel>
(1) Calculation of unit heating value
Heating value (W)
Total heating value of units (W):
28W (= control unit + display unit + keyboard unit + operation panel I/O unit)
Total heating value (W) by machine input (D1):
5.6W (= 24V;
total heating value when the 32 points are simultaneously turned ON × 7.3mA × 32)
... 24V; current consumption per point of the operation panel I/O unit DI ÷ 3.3kΩ ≒ 7.3mA
Total heating value W = 33.6W (28 + 5.6)

3. General Specifications (Environment Conditions)
(2) Calculation of operation panel cooling capacity
Tolerance value for temperature rise (Δt)
Panel internal temperature (according to each unit’s specification) T ≤ 55C° Panel peripheral temperature (according to machine’s specification) Ta ≤ 45C°
Tolerance value for internal temperature rise ΔT = 10C° (T – Ta)
Heat radiation area (A)
The surface of the molded unit, which has lower radiation capacity than the metal plate surface,
should be excluded for the heat radiation area in principle. The bottom of the operation panel, which has difficulty in radiating due to the temperature distribution, should also be excluded for the heat radiation area in principle.
Heat radiation area A = 0.71mm
(≒ 0.6 × 0.12 + 0.6 × 0.5 × 2 – (0.2 6 + 0.14) × 0.2 + 0.12 × 0.5 × 2)
(Top surface) (Front, rear surface) (Unit surface) (Both sides surface)
Operation panel cooling capacity (W1)
Calculate the cooling capacity to keep the temperature rise in the operation panel less than 10°C.
Cooling capacity W1 = 42.6W (6 × A × ΔT)
(3) Comparison of heating value and operation panel cooling capacity
The operation panel cooling capacity is over the heating value, which presumed no need to install the heat exchanger.
(4) Confirmation with the actual machine
The result of the calculation above is only a rough indication. The actual temperature rise may differ according to the structure of the operation panel. Be sure to confirm the temperature rise value in the operation panel when the machine is run ning.
