Power-on procedure
1)
Always wire the power supply
as
shown
in
above Section
3.7.1
using the relay with the main
circuit power supply. Configure up an external sequence to switch
off
the relay as soon as an
alarm occurs.
2) Switch on the control circuit power supply P24L, P24G simultaneously with the main circuit
power supply or before switching on the main circuit power supply.
If
the main circuit power
supply
is
not on, the &splay shows the corresponding warning. However, by switchng on the
main circuit power supply, the warning &sappears and the servo amplifier wd operate properly.
3)
The servo ampuler can accept the servo-on signal
(SON)
about
1
second after the main circuit
power supply
is
switched
on.
Therefore, when
SON
is
switched on simultaneously with the
24V
power supply, the base circuit wd switch on in about
1
second. and the ready signal
(RD)
wdl
switch on in further about 20ms, malung the servo ampM1er ready to operate.
