Caution : We recommend the following noise filter for an measures against EMC
Directive.
à
PN2070-10/06 (Schaffner) equivalent
(Use a breaker compatible with the European Safety Directives.)
！
Caution : Provide a circuit to shutdown the main power by an output of an alarm.
à
When an alarm is given, #2 and #15 of CN2 for DRDY (Driver Unit ready) outputs
open.
l
Alarm of “Main AC Line Trouble” will be given when the main power is turned off while the
servo is on. This alarm cannot be cleared until the control power is turned on again.
(Refer to “7-1.1. Servo on.”)
