4.10.1. Latching

Workflow

The registration process is described below. Detailed instructions
for the use of the commands and variables are provided in the
sections that follow.

♦ Define a condition for latching using the LATCHING_TRIGGER

command. Possible conditions are:

Input 6 (connected at CN1-46) changes from 0 to 1

(Rising Edge).

Input 6 (connected at CN1-46) changes from 1 to 0

(Falling Edge).

♦ Start motion:

The registration process can be applied in the following

motion modes: Position, Velocity, Hunting, Pulse-Train,
and Analog Speed. See Section 5.3, Motion Modes.

♦ After 62.5ms of the condition being met:

The variable Latched_position_ready changes from 0 to 1.

The variable Latched_motor_position is set to the current

position of the motor, in position user units.

The variable Latched_master_position is set to the

current position of the master (if in use), in encoder

counts.

♦ Perform the next step only once the Latched_position_ready

variable has changed from 0 to 1.

Use the command WAIT_VAR

or assign an interrupt conditional on this variable.

♦ Define the distance from where the input is received to

where the motor must stop using the
REGISTRATION_DISTANCE command.

The deceleration caused by registration is defined by the

variable Profile_acceleration. When specifying the

registration distance, ensure that it is sufficiently long for
the motor to be able to decelerate to a stop at the profile
acceleration.

♦ The motor decelerates to a stop.

Under certain circumstances, the motor will not stop at

the point command by REGISTRATION_DISTANCE. See
