Applied Functions
Operation Timings when Alarm Generates (Servo ON)
*1. Dynamic brake operation at an alarm depends on the Stop Selection for Alarm Detection (Pn510) setting.
*2. The Brake Interlock output (BKIR) signal is output when the OR condition is met by a release request command from
the Servo control and from the MECHATROLINK-II. In the above example, the MECHATROLINK-II makes no
release request. The BKIR signal is assigned to the general-purpose output (CN1).
*3. The mark t1 refers to the period until the value becomes lower than the set value on the Brake Timing during
Operation (Pn438) or the Brake Release Speed Setting (Pn439), whichever is shorter.
Note 1.Even when the servo ON input is turned ON again while the motor is decelerating, the system does not enter
the servo ON state until the motor stops.
Note 2.If the main circuit power supply turns OFF while the motor is operating, a phase loss alarm or main circuit voltage
low alarm occurs, in which case this operation timing is applied.
