8.10 Brake
The brake output on connector X2 controls a mechanical brake that optionally may be fitted to a motor. The brake
is applied and released relative to the Drive Active state of the drive. You can modify the release and apply
delays using the parameters shown below.

Brake Release Delay The time between the drive being active
and the brake being released.
MOTOR.TBRAKERLS
Brake Apply Delay The time between the brake being applied
and the drive not being active.

8.11 Using Position Capture
8.11.1 Overview
Position capture allows you to precisely determine what the motor position (or drive clock time) was when a spe-
cific event triggers. The AKD drive uses two independent captures, which operate similarly. The descriptions pro-
vided in this user guide refer to Capture 0, but also apply to Capture 1.
Position capture is used in precision environments, where the motor may be moving at very high velocities, an IO
is triggered, and you must know exactly where the motor was when the event occurred. Homing algorithms often
use position capture.
Position capture will capture the motor position (or drive clock time) when the capture trigger is activated. The
capture engine operates on a faster clock than the 16 kHz clock used in the scope and recorder. This faster clock
allows the position capture to obtain more accurate results than those obtained using the scope or recorder clock.
8.11.2 Configuring Position Capture
To configure the position capture, select Position Capture from the Settings group:
