14.1.4 Connections to SGD-
N SERVOPACK
(1) Connection Example
* 1. Brake control relay
* 2. There are 200-V and 100-V brake power supplies.
(2) Parameter Settings
The SERVOPACK parameters related to controlling the brake are described below.
(a) Cn-12 (Brake ON Timing after Motor Stops)
Adjust brake timing with the following parameter if the machine moves slight due to gravity or other factors.
When using a servomotor with a brake, set the timing of turning OFF the Servo (i.e., stopping the motor out-
put) in reference to the output signal that controls the brake (/BK).
This parameter is used to set the timing when the motor is stopped. Brake operation while the motor is running is set in Cn-
15 and Cn-16.
For the standard settings, the Servo will turn OFF simultaneously with the /BK output (Brake Operation). If gravity will
cause the machine to move slightly at this time due to machine configuration or brake characteristics, turning OFF the
Servo can be delayed to make sure there is no movement.
