Operation
Pn507 Brake command speed
Setting 0 to 10000
range
Pn508 Brake timing 2 (all operation modes)
Setting 10 to 100
range
• This parameter sets the BKIR (brake interlock output) timing to control the electromagnetic brake ON/
OFF when a Servomotor with a brake is used.
• This setting prevents damage to the machinery and the Servomotor holding brake.
• PN506 (brake timing 1): Set the lag time from BKIR OFF to servo OFF.
• Pn507 (brake command speed): Set the rotation speed for turning OFF BKIR.
• Pn508 (brake timing 2): Set the standby time from servo OFF to BKIR OFF.
• When RUN is OFF while the Servomotor is stopped, first turn OFF BKIR, wait for the duration set in
Pn506, then turn OFF the servo.
• When RUN is OFF while the Servomotor is stopped, if a servo alarm occurs, and the main circuit pow-
er supply is OFF, the Servomotor will decelerate and the rotation speed will fall. When the rotation
speed falls to below the Pn507 setting, BKIR will be turned OFF.
Note 1. Related parameter: Pn50F.2 (BKIR signal output terminal allocation).
Note 2. Refer to Brake Interlock for details of brake interlock functions.
Pn509 Momentary hold time (All operation modes)
Setting 20 to 1000
range
• Sets the time during which alarm detection is disabled if a momentary power failure occurs.
• When the power supply voltage to the Servo Driver is OFF, the Servo Driver detects that the power
supply is OFF and turns OFF the servo. The 20 ms default setting means that if the power supply volt-
age is recovered within 20 ms, operation will continue without the servo being turned OFF.
• In the following cases, the servo is turned OFF regardless of the Pn509 setting:
S If the load is too great, and A.41 (insufficient voltage) occurs during a momentary power stop-
page.
S If the control power supply falls during a momentary power stoppage, and cannot be controlled.
