SYNTAX xx SU nn or xx SU ?
PARAMETERS
Description xx [ int ] - axis number
nn [float] - encoder resolution
Range
xx - 1 to MAX AXES
nn - 2e-9 to 2e+9 in user defined units
or ? to read present setting
Units
xx - none
nn - none
Defaults
xx missing: error 37, AXIS NUMBER MISSING
out of range: error 9, AXIS NUMBER OUT OF RANGE
nn missing: error 38, COMMAND PARAMETER MISSING
out of range: error xx2, PARAMETER OUT OF RANGE
DESCRIPTION
This command is used to set the encoder resolution for axis xx .
Note:
The encoder resolution can only be changed when encoder feedback is enabled.
See ZB command.
RETURNS If “?” sign takes the place of nn value, this command reports the current setting
REL. COMMANDS
FR - set full-step resolution
SU - set encoder resolution
QD - update driver
ZB - set feedback configuration
EXAMPLE
2SU? | read encoder resolution setting of axis # 2
0.0001 | controller returns a value of 0.0001 units for axis #2
2SU0.0005 | set encoder resolution to 0.0005 units for axis #2
2QD | update programmable driver with latest settings for axis #2
SM | save all controller settings to non-volatile memory
