Also if the servo control is turned on with asignificant level of position deviations/external scale deviations, the motor may make an abrupt start in order toperform the control to set the deviations to 0. Use due care when using the system with the positiondeviations/external scale deviations retained.*3 If an error occurred with main power supply turned off, the system operates in accordance with Pr5.10 “Sequenceat alarm”.*4 “During deceleration” refers to the section from the state where the motor is operating until the speed is reduced to30 r/min or below. Once the speed reduction achieves 30 r/min and thus it transfers to the “After stop” state, thepost-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 tozero after shifting to off-status of main power supply.*6 Pr5.07「Torque command additional value」set the offset toque to be added to the torque command.。Please take notice of that dynamicbrake cann’t be appointed as decelerating or stoping.
