3.7 I/O Signals
50
3.7.5 Servo Alarm Output
The usual connection for alarm related output signals is shown below.
These signal is output when the SERVOPACK detects an error.
A 24-VDC power supply must be connected externally.
Note: Open collector outputs are used for output signals.
• At alarm occurrence, an alarm code is output to the host controller through MECHATROLINK-II
transmission. Take care that the SERVOPACK power supply is not turned OFF when the alarm out-
put signal turns ON.
• Configure the system so that the SERVOPACK power supply is turned OFF by the contact signal
between C1 and C2 of the regenerative unit or the contact signal of the thermometal cut-out for the
external resistor.
The power supply must be turned OFF and the emergency stop input signal must be open when
using the system emergency stop.
3.7.6 Brake Interlock Output
The usual connection for brake interlock signal /BK is shown below.
These signal turns ON when the servo turns ON, and OFF when the servo turns OFF. They are used
to control the brake. The brake can also be released by sending a release brake (BRK_OFF) com-
mand using MECHATROLINK-II communications.
