Voltage supply of processor logics
(demands on power supply module) • DC 24 V (20 ... 30 V)
•
≤
0.6 A
• The voltage output of the power supply
unit must comply with the SELV or
PELV type.
Inrush current limitation of the
processor logics • The JM-204-480 is equipped with a
220 µF capacitor for buffering. The
inrush current is not limited.
Internal ballast resistor • Resistor: approx. 120 .(PTC)
• Continuous power: 75 Watt
Power consumption depends on the
present temperature of the heat sink
• Maximum capacity: 1 kW for 0.6 s
• Overload protection internal (warning
and error)
External ballast resistor In order to achieve greater brake power, an
external ballast resistor can be installed.
For this, see “Connection of External
Ballast Resistor and DC link Circuit of
Another JM-204-480" on page 64.
Residual voltage To avoid hazard of electrical shock wait at
least 7 minutes after switching-off the
digital servo amplifier before attempting to
pull out the plug or remove this unit (see
page 19).
