7.3.4 Zero speed output
When the absolute value of the actual speed of the motor is less than P5-42 (zero speed judgment
threshold), and the duration reaches the set time of P5-40 , the servo drive outputs the zero-speed
signal Z-SPD. If the absolute value of the actual speed of the motor is greater than P5-42, the
zero-speed signal Z-SPD will not be output.
The zero speed output is not dependent on the control mode or the state of the servo motor. This
allows users to use this output signal as notier of ongoing motion at the motor.
