11.1.2 Connections to Σ-II, Σ-III, Σ-V, or Σ-7 Series SGDM, SGDH, SGDS, SGDV, and SGD7S SERVOPACKs
( 2 ) Parameter Settings
The SERVOPACK parameters related to control the holding brake are described below.
Parameter
Pn50F.2 Output Signal Selection 2
Details
The following parameter determines which CN1 pin (0 to 3 above) will be used to output the /BK signal.
/BK brake
interlock output
Parameter
Pn506 Brake ON Timing after Motor Stops
Details
This parameter adjusts the delay time from /BK Signal Output until Servo OFF (stopping Servomotor output), and
it is used to be set when the machine moves slightly due to gravity or other factors after turning the brake ON.
 This parameter is used to set the timing when the motor is stopped. Brake operation while the motor
is running is set in Pn507 and Pn508.
 For the standard settings, the Servo will turn OFF simultaneously with the /BK output (Brake Opera-
tion). If gravity causes the machine to move slightly at this time due to machine configuration or
brake characteristics, turning OFF the Servo can be delayed to reduce the movement.
Parameter
Pn507
Brake ON Timing when Motor
Running
Pn508
Details
Pn507: Speed Level for BK Signal Output when Motor Running
Pn508: Timing of BK Signal Output when Motor Running
These settings are used to set the timing for applying the brake when the Servo turns OFF due to an /S-ON input
signal or alarm.
