Applied Functions
Operation Timing
This section shows the timing of the Brake Interlock Output (BKIR).
Basic Timing
Servo ON/OFF Operation Timing When Motor Is Stopped
*1. The servo does not turn ON until the motor rotation speed drops to approx. 30 r/min or below.
*2. The operation of the dynamic brake when the servo is OFF depends on the setting of the Disable operation option
code (605C hex).
*3. The Brake Interlock Output (BKIR) signal is output either when a release request command is received via Servo
controls or when a release request command is received via EtherCAT communications. The above example shows
when there is no brake release request from EtherCAT communications. The BKIR is assigned to the general-
purpose output (CN1).
Note: The brake application time and release time vary depending on the Servomotor brake. For details, refer to 3-3
Servomotor Specifications on page 3-32.
