LOG Mathematics Function
ACTION: Returns the natural logarithm of a numeric expression.
PROGRAM SYNTAX: LOG(expression) - used in an expression
REMARKS: The argument expression must be greater than zero. The natural loga-
rithm is the logarithm to the base e. The constant e is approximately
equal to 2.718282.
You can calculate base 10 logarithm as follows: LOG 10(x)=
LOG(x)*.4342945
EXAMPLES: x=LOG(2.718282) ‘ sets x= 1
LOWSPD Trajectory Parameter
ACTION: Sets or returns the Low Speed (starting speed) value of a stepping mo-
tor axis.
PROGRAM SYNTAX: LOWSPD(axis)=expression
LOWSPD=expression1, ... ,expression 8
LOWSPD(axis, ... ,axis)=expression, ... ,expression
