SOFTLIMNEG Over Travel Limit
ACTION: Programmable software limit switch for motion in the negative direc-
tion. Sets or returns the absolute negative travel position value for the
specified axis.
PROGRAM SYNTAX: SOFTLIMNEG(axis)=expression
SOFTLIMNEG=expression1, ... ,expression8
SOFTLIMNEG(axis, ... , axis)=expression, ... , expression
SOFTLIMNEG(axis) - used in an expression
REMARKS: The "axis" specifies the number of the axis (1-8).
The expression sets the absolute value for the negative direction soft
limit in units.
If during motion the absolute position becomes less than its software
limit value, the motion is aborted.
Software travel limits are used to stop the motor when the commanded
position exceeds the programmed software travel limit. There are two
software travel limits, one for + and one for - motor rotation. The +
software travel limit is tested when the motor is rotating in the + direc-
tion. The - software travel limit is tested when the motor is rotating in
the - direction.
The software travel limits are checked if they are enabled and a motion
other than MOVEHOME is occurring.
The software travel limits power up disabled.
When the travel limit is exceeded, the motor is decelerated to a stop
using the Max. ACCEL value, and an error code is set.
EXAMPLES: SOFTLIMNEG(2) =-4
Sets the negative direction soft limit of axis 2 at -4 units.
SOFTLIMNEG=-5,,-6
Sets the negative direction soft limit of axis 1 at -5 units and axis 3 is set
to -6 units.
SOFTLIMNEG(1,3)=-5,-6
Sets the negative direction soft limit of axis 1 at -5 units and axis 3 is set
to -6 units.
