4.2.9. Stop motion modes
There are two stop motion modes in the controller:
emergency stop;
stop with deceleration.
Emergency stop
Emergency stop is initiated by the command STOP. The controller tries to instantly stop the rotation of the motor shaft. This can lead
to missed steps in a stepper motor, if no feedback is used. Abrupt cessation of movement can adversely affect the equipment, for
example, may shift samples on the microscope stage or require additional adjustment of the optical line after a sudden stop.
Warning. When the controller is configured to trigger a stop on the left/right limit switch, it always occurs
immediately when the stage reaches the limit switch. This should be avoided.
Stop with deceleration
Stop with deceleration is initiated by the command SSTP. A smooth stop occurs with deceleration Deceleration, if it is not disabled in
the acceleration mode settings.
Warning. If the acceleration mode is disabled, then there is no difference between the emergency stop and the stop
with deceleration. An SSTP command will then result in an immediate stop.
