(2) Front CF card I/F (CF)
It is recommended to use CF cards of the original equipment manufactured parts.
Mitsubishi is unable to guarantee the machine operation when a commercially available CF card or SD memory
card (SD-CF adapter is required) is used. In that case, performance check must be made carefully by machine tool
builder.
(Refer to "General Specifications: Exclusive CF cards for MITSUBISHI CNC: Precautions for Use of Commercially
Available CF Cards".)
(3) Display unit backlight driver I/F (INV)
(4) 24VDC input (DCIN)
<Cable side connector type>
Connector: 2-178288-3
Contact: 1-175218-5 x3
Recommended manufacturer: Tyco Electronics
(a) Specifications of power supply
Consider the following characteristics when selecting the stabilized power supply (prepared by machine
tool builder). Use a power supply that complies with CE Marking or that follows the safety standards given
below.
[Stabilized power supply selection items]
[Standards]
Safety Standards: UL1950, CSA C22.2 No.234 approved, IEC950 compliant
Noise Terminal Voltage: FCC Class A, VCCI-Class A
High Harmonics Current Restrictions: IEC61000-3-2
(Note) 24VDC voltage may drop instantaneously due to rush current at the beginning of 24V power
supply to the control unit. The level of voltage drop depends on the capacity of the power
supply. Do not share the power supply with the devices that have alarms to warn the voltage
drop.
1 I+24V
2 0V
3 FG
Item Standard setting
Output Voltage fluctuation ±5% or less of 24VDC
Ripple noise 200mV (P-P)
Power capacity 2.5A or more
Output holding time 20ms
Overcurrent protection Required
CAUTION
1. Using a stabilized power supply without overcurrent protection may cause the unit's failure due to miswiring of
24V.
