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
