S oftware Limit
6 4 B
The system is designed to mechanically set the limit (+) and limit (-) to restrict the moving range of a
motor.
Separately from the mechanical limits (+) and (-), the software limit is a function to add the limits in
software for the absolute coordinate managed within the positioning unit RTEX. As the software limit is a
function for the protection of the motor and AMP, it is recommended to set them to the values within the
range of the mechanical limits (+) and (-) as below.
When exceeding the setting range of the software limit (upper and lower limit values), an error occurs,
and the deceleration stop is executed. It is necessary to clear the error and move the motor into the
range of the software limit using an operation such as JOG operation after the stop.
Whether the software limit is set to be available or not can be specified individually for the positioning
control, JOG operation and home return each. For example, it is possible to set the limit software to be
invalid only in the home return operation.
