Overrun Protection
This function detects an Overrun Limit Error (Error No. 34.0) and stops the Linear Motor if the motor
exceeds the allowable operating range set for the Overrun Limit Setting (3514 hex) with respect to the
position command input.
The function can also prevent the Motor from crash into the machine edge due to vibration.
The overrun limit works under the following conditions.
The position command input range will be cleared to zero under any of the following conditions.
•
When the power supply is turned ON,
•
While the position error is cleared. This includes when the servo is OFF and when the error
counter is cleared due to a deceleration stop for the drive prohibit input.
•
When a trial operation via USB communications starts and when it ends.
•
When Speed Control or Force Control is enabled.
•
When the position data is initialized. This includes at a component setup request, at homing,
when setting the coordinate system and at an adjustment command.
•
When magnetic pole position estimation is in progress.
Precautions for Correct Use
Precautions for Correct Use
•
This function is not intended to protect against incorrect position commands.
•
When this function works, the motor decelerates and stops according to the Fault reaction
option code (605E hex). However, the load may hit the machine edges during deceleration,
causing damage. Take this deceleration operation into account when you set the Overrun Limit
Setting (3514 hex).
•
The overrun limit function is disabled for FFT analysis from the CX-Drive.
