NSD Varlimit VS-212DN User Manual

6-10
(6) For the parameter format, the VS-212DN automatically identifies the direction by referring to the
current position every 100 ms inside the VS-212DN.
However, when an MRE series sensor is used, the following reverse direction speed will be interpreted
as a forward direction operation.
(7) The following conditions must be satisfied in order for the current position preset function to be
operative:
a) The current position preset function must be designated as “enabled” at the parameter setting.

b) Any sensor error must be reset.
c) RUN or TEST mode must be designated, with an online status established.
d) “1” is not designated at the “current position preset input disabled” setting area.
Preset inputs are disabled when “1” is designated at the relevant bits at the “current position
preset input disabled” setting area.
(8) The current position preset function will not occur if the current position preset input is already ON
when the power is turned ON.
(9) If both the current position preset 1 and 2 inputs are executed simultaneously, the “current position
preset 1 input” function will be executed and the “preset 2” input will be ignored.
(10) If an current position preset input occurs during a STOP status, a forward direction will be adopted.
(11) Once an current position preset input has been received, subsequent current position preset inputs
will be ignored for a period of 100 ms.
(12) When the current position preset function is executed during a positioning operation, and if the
resultant positioning is to be in the reverse direction, motion will be stopped momentarily and then
automatically re-started.
(13) Depending on the minimum unit of current position change (resolution), there may be cases in which
the current position value will vary slightly from the current position setting value. When the current
position value is between the minimum units, the larger value will be selected.
Ex.) Current position value change: 0 → 7 → 15
Current position setting value: 10
Because the current position setting value is between 7 and 15, the larger value of “15” will
be designated as the current position value.
