*1 “Immediate stop” refers to the control to stop immediately with the servo control on.
Torque command values for that case are restricted by Pr5.11 “Torque setup for emergency stop”.
*2 If position commands keep coming or the motor stays running with the main power off, the position deviations may
accumulate to result in Err24.0 “Position deviation excess protection”. Also if the servo control is turned on with a
significant level of position deviations/external scale deviations, the motor may make an abrupt start in order to
perform the control to set the deviations to 0. Use due care when using the system with the position
deviations/external scale deviations retained.
*3 If an error occurred with main power supply turned off, the system operates in accordance with Pr5.10 “Sequence
at alarm”.
*4 “During deceleration” refers to the section from the state where the motor is operating until the speed is reduced to
30 r/min or below. Once the speed reduction achieves 30 r/min and thus it transfers to the “After stop” state, the
post-stop actions will be performed regardless of the motor speed.
*5 Position deviation/External scale deviation is cleared before and after slowing down. They are always cleared to
zero after shifting to off-status of main power supply.
