Protective Functions
The Servo Drive has built-in protective functions. When a protective function is activated, the
Servo Drive turns OFF the alarm output signal (ALM) and switches to the Servo OFF status.
The alarm code will be displayed on the front panel.
Warning Function
The Servo Drive issues a warning before a protective function is activated, allowing you to check
overload and other status in advance. A warning is also issued for a network error, allowing you
to check the network status.
