Parameters Details
Explanation of Set Values
If an error occurs when servo is turned OFF, the operation will be based on the Stop Selection for
Alarm Generation (Pn510). Additionally, if the main power supply is turned OFF when servo is
OFF, it will be based on the Stop Selection with Main Power Supply OFF (Pn507).
*1. Immediate stop refers to applying control while servo is still ON and stopping the operation
immediately.
At that time, the torque command value is restricted by the Immediate Stop Torque (Pn511).
*2. If the position command is given or the motor runs continuously when servo is turned OFF, the
position error accumulates and Err24.0, "error counter overflow," may occur. In addition, if servo is
turned ON when the position error or external scale error is a large value, the motor may operate
abruptly to perform a control operation to bring the error to 0. Take sufficient care when using while
holding the position error or external scale error.
*3. Decelerating refers to a period between when the motor is running and when the motor speed reaches
30 r/min or less. Once the motor reaches a speed of 30 r/min or less and moves to the after stop
status, follow the subsequent operation based on the after stop status regardless of the motor speed.
*4. The position error or external scale error will always be cleared to 0.
