13.2 Software Limit13-313.2 Software LimitThe system is designed to mechanically set the limit (+) and limit (-) to restrict the movingrange of a motor.Separately from the mechanical limits (+) and (-), the software limit is a function to add thelimits on software for the absolute coordinate managed within the unit. As the software limit isa function for the protection of motors and servo amplifiers, it is recommended to set them tothe values within the range of the mechanical limits (+) and (-) as below.Table(-) side (+) sideLimit (+)Ball screwLimit (-)Lower limit value ofsoftware limitUpper limit valueof software limitWhen exceeding the setting range of the software limit (upper and lower limit values), an erroroccurs, and the deceleration stop is executed. It is necessary to clear the error and move themotor into the range of the software limit using an operation such as JOG operation after thestop.Table(-) side (+) sideLower limit value ofsoftware limitThe table can move within the settingrange of the software limit.Whether the software limit is set to be available or not can be specified individually for thepositioning control, JOG operation and home return each. For example, it is possible to setthe limit software to be invalid only when returning to the current value.
