The time t1 will be either the value used to set Pr4.38 “Mechanical brake action at running setup” or whenthe motor speed is reduced to the setting for Pr4.39 “Brake release speed setup” or less, whichever comesfirst.*2. If the SRV-ON signal is turned on again during the deceleration of the motor, the servo control does not transfer to theservo-on state until the motor stops.*3. The operation of the dynamic brake during the servo-off is according to the setting value for Pr5.06“Sequence at servo-off”.*4. The servo control is not turned on until the motor speed is approximately 30 r/min or less.*5. Whether electricity is turned on to the motor during the servo-off deceleration depends on the valueused to set Pr5.06 “Sequence at servo-off”
