2.CONFIGURATION FANUC AC SERVO AMPLIFIER β series B-65232EN/03
- 134 -
WARNING
At the power input of the power magnetics cabinet, install a surge absorber between
the power lines and between each power line and a ground to protect the unit from a
voltage surge caused by lightning.
See Section 7.5 for details of the lightning surge absorber.
NOTE
1 When no separate regenerative resistor is used, a dummy connector for connecting
the overheat alarm (OH alarm) for separate regenerative resistors and a dummy
connector for connecting a resistance wire are required.
Specify the ordering drawing number A06B-6093-K314 when ordering dummy
connectors for connecting the OH alarm and resistance wire.
Specify the ordering drawing number A06B-6093-K315 when ordering a housing
and contact for connecting a separate regenerative resistor with a β series amplifier.
2 When multiple β series amplifiers are connected, and a wire with a diameter of 0.5
mm
2
or more needs to be used, select this connector. The supply current of the
control power supply per β series amplifier is 0.6 A for the FSSB interface, 0.9 A for
the I/O Link interface, or 0.4 A for the PWM interface. So, select an appropriate wire
according to the number of β series amplifiers to be connected.
3 There are two methods of connecting the batteries for the absolute pulse coder.
Specify an appropriate connection method according to the use environment.
4 See Section 3.2, "DERATING", to choose whether to cool the β series amplifier by
natural air cooling or by forced air cooling.
For forced air cooling, a fan motor with a wind speed of 2 m/sec is required.
A desired cooling capability can be obtained by using a fan adapter.
For the attachment of a fan adapter, see Section 9.2, "PANEL CUT-OUT
DRAWING" for forced air cooling.
When using forced air cooling, design a power magnetics cabinet so that cooling air
from the fan motor does not leak. The fan motor may need to be maintained and
replaced, depending on the use environment. So, give a consideration to the
installation and structure of a fan motor so that maintenance and replacement work
can be performed easily.
