Switch for main power operation<br />
Plan the sequence circuit to operate the switch for main power individually by [alarm] signal and<br />
[emergency stop] signal.<br />
Notices for switching main power<br />
Since the HA-655 driver provides a capacitor for an input filter of a rectifier circuit, large transient current<br />
flows at every operation of main power switch. If the switching operation is too frequent, resisters for<br />
suppressing the transient current may deteriorate.<br />
The switching frequency should not exceed 5 times in an hour and 30 times in a day. Furthermore, the<br />
interval between turning OFF and ON should keep more than 30 seconds.<br />
Do not make switching operation (turning ON or OFF) at the state that the servo -ON [CN2-3:S-ON] is<br />
ON.<br />
