Driver card
●
Switching power supply (24V DC)
●
24V DC battery
3 A 72 W or more per MDR
■
A switching power supply is recommended as the DC power supply (24 VDC±10%) for
drivers.
■
Use a stabilized power supply that has an adequate capacity of 24V DC and 3A or
higher and does not fluctuate due to load variation.
■
If the power supply capacity is smaller than the rated power of the dedicated driver card
multiplied by the number of MDRs to be used, the supply voltage may drop and cause
failure or damage of the MDR and driver card. Be sure to use a power supply with a
capacity larger than the rated power of the dedicated driver card multiplied by the
number of MDRs to be used.
＊
When starting multiple MDRs simultaneously, use a power supply with a capacity of
3A multiplied by the number of MDRs to be used.
■
For the power supply unit, use an isolation type switching power supply compliant with
the safety standard (IEC60950-1 or UL60950-1). Do not use a non-isolation type power
supply for safety reasons, since it may not conform to the radiation noise regulations.
■
A transformer type power supply cannot be used.
■
Secure a voltage of 24V DC±10% at the power supply terminal of a driver card.
■
The power supply should not activate protection with peak current 20A, 1 ms or below.
■
The safety circuit includes the emergency stop equipment and magnet
contactor.
