Selecting Stopping Method Selecting stopping method (n04) Selects the stopping method suitable for application. Setting Description 0 Deceleration to stop 1 Coast to stop • Deceleration to stop Example when accel/decel time 1 is selected ACCEL OUTPUT FREQUENCY TIME 1 (n16) DECEL TIME 1 (n17) * DECEL TIME 1 (n17) * TIME FWD (REV) RUN COMMAND ON MIN. OUTPUT FREQUENCY (FREQUENCY AT DC INJECTION BRAKING START) n14 (FACTORY SETTING: 1.5Hz) DC INJECTION BRAKING TIME AT STOP (n53) (FACTORY SETTING: 0.5s) * When frequency reference is changed during running. Upon termination of the FWD (REV) run command, the motor decelerates at the decel rate determined by the time set to deceleration time 1 (n17) and DC injection braking is applied immediately before stop. DC injection braking is also applied when the motor decelerates by setting frequency reference lower than min. output frequency (n14) with FWD (or REV) run command ON. If the decel time is short or the load inertia is large, overvoltage (OV) fault may occur at deceleration. In this case, increase the decel time. 60
