MAINTAIN [Axis] = [0 to 3]…
Function: The maintain command specifies the behavior of the controller after move completion.
Move commands complete when the stage moves to within the
finish error tolerance of
the target position (PCROS command). The actions for various code values are:
code = 0 [default] Post-move, when the controller detects drift from target specified by
the drift error value, it will return the stage axis to the target several times (18) within a
timeout period (~0.5 sec.) before declaring a move error code 60 and giving up further
attempts.
code = 1 Post-move, the controller will indefinitely continue to try to reach target when
drifts greater than the drift error are detected.
With codes 0 and 1, the motor drivers are turned off when the stage reaches the finish
error tolerance.
code = 2 The motor drivers remain on and the servo loop remains active. (Version 8.5+)
code = 3 Drivers remain on and servos active for the post-move time set by the WAIT
command. The system BUSY is released when the finish error tolerance is first achieved.
Setting the WAIT time sufficiently long can stabilize post-move drifts during data
recording, but then allow for less power consumption of the driver amplifiers when
waiting between moves.
code = 4 , is a Piezo only mode where a tunable speedup algorithm is applied to moves.
The tuning is done by the user setting two parameters using the
PZ
command. The
user sets up an intentional overshoot amount and a maximum time for the overshoot to
be applied. When a move is initiated, the piezo moves towards the overshoot position
until the maximum time is reached or else until the measured position (using the strain
gauge) has reached the halfway point between the previous position and the intended
(non-overshoot) position. Subsequently the command signal to the intended position is
applied. Experimentally this can reduce settling time by 10-60%. The overshoot amount
is set using
[#Addr]PZ T
, expressed in percent. The maximum time to move
towards the overshoot position is set using
[#Addr]PZ F
, expressed in milliseconds.
Mode 4 does not function with CRISP-enabled firmware.
This is an Axis-Specific Command.
Reply: If there are no errors, the positive reply
:A
will be sent back from the controller.
