* Caution for Absolute Encoder
If an integer multiplied vicinity number to the distance between
Z-phases is set to this parameter, there could be a concern that
the coordinate slide for a pitch of a pulse between Z-phases as
the servo lock may occur on the Z-phase at the absolute reset.
Make sure that you will never establish the setting to an integer
multiplied vicinity number to the distance between Z-phases.
Ensure enough margin to the servo system vibration width.）

Push stop check time at
home return
Common 1500 1 ~ 5000 msec Used to confirm pusing action at the time of home return.
25
Push stop check time at

29 VLMX speed Common 800 1 ~ 9999 mm/s
During VLMX operation, the maximum operating speed of each
axis or VLMX speed, whichever is lower, is used as the maximum
speed of the applicable axis.

Brake equipped: Time after receiving a servo-ON start
response until start of brake unlocking
Brake not equipped: Time after receiving a servo ON start
response until transition to an
operation-enabled status

Actual distance between
phase Z and end
Common 0 -1 ~99999 0.001mm
Absolute distance from the end (Mechanical or LS). Obtained
automatically if the distance is a negative value. When multiple
actuators are combined, it is recommended to write the flash
ROM after automatic acquisition.
