Applied Functions
Operation Timings when Alarm Generates (Servo ON)
*1. The dynamic brake operation when an alarm generates depends on Stop Selection with Servo OFF (Pn506).
*2. t1 is the set value of Brake Timing during Operation (Pn438), or the time needed for the motor rotation speed to
drop to 30 r/min or below, whichever occurs first.
Note 1.Even when the servo ON input is turned ON again while the motor is decelerating, the system will not enter the
servo ON state until the motor stops. The brake interlock (BKIR) signal is allocated to a CN1 general-purpose
output to be used.
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 will occur, in which case this operation timing will be applied.
