Chapter 8 Motion Control Function
2. Soft high/low limit
(1) Software stroke high/low limit is a function that does not perform the operation in out of the range of soft high/low limit set
by users.
(2) Software stroke high/low limit of each driving axis can be set by using software package or axis parameter change
function.
(3) If the axis is outside the range of stroke, axis error occurs.
(4) When the axis is positioned outside the range of stroke, operation of the axis is impossible except for jog. Operation can
be resumed by moving it inside the range of stroke through jog operation or resetting the current position to the inside the
stroke range.
(5) Software high/low limit are don’t detect in the following cases.
• In case soft upper limit value and lower limit value are set to the initial value ( upper limit: 2147483647, lower limit: -
2147483648)
• Software upper limit value and lower limit value are set to the same value (software upper limit = software lower limit)
• In case of the operation with speed control when expansion parameter “S/W limits during speed control” is set to ” 0:
Don’t detect”
(6) Relevant parameter setting
Set the range of software limit function
