Origin setting using the current position clear function
 Assigning "Clearance of position deviation [PCLR] (47)" to the input terminal and turning on that
terminal clears "Current position monitor [d030]" to zero.
 Moving to the position that will be the origin beforehand and turning on [PCLR] determines the
origin.
 [PCLR] is enabled when "Pulse input, target function selection [P003]" is set to "Speed feedback
(01)" regardless of the setting of "Simple positioning selection [P012]".

Clearance of position deviation [PCLR]:
When "Pulse input, target function selection [P003]" is
"Speed feedback (01)", turning this signal on clears
"Current position monitor [d030]" to zero.

Origin setting using the current position preset function
 The current position preset function specifies the current position to the position set in "Pre-set
position data [P083]". This is used when there is an offset between the origin position ([ORL]
signal input position) and the actual origin when the returning function is used.
 Assigning "Position data presetting [PSET] (91)" to the input terminal and turning on that
terminal allows "Current position monitor [d030]" to be "Pre-set position data [P083]".
 When using the current position preset function, set "Position control mode selection [P075]" to
"Limit (00)". When "No Limit (01)" is selected, it is not enabled.
 [PSET] is enabled when "Pulse input, target function selection [P003]" is set to "Speed feedback
(01)" regardless of the setting of "Simple positioning selection [P012]".
