6.12.2 Regenerative power ride-through control

E6580757

Application!!

• A waiting time of 200 to 1,000msec is preset to allow the residual voltage in the motor to decrease to a certain level during restart. For this reason, the start-up takes more time than usual.

• Use this function when operating a system with one motor connected to one inverter. This function may not operate properly in a system configuration with multiple motors connected to one inverter. Application to a crane or hoist

The crane or hoist may have its load moved downward during the above waiting time from input of the operation starting command to the restart of the motor. To apply the inverter to such machines, therefore, set the auto-restart control mode selection parameter to "0" (Disabled), and avoid using the retry function. If retry function is enabled the load could move downward causing damage and or injury.

• Function

	Regenerative power ride-through control continues the operation of the motor by utilizing motor re-
								6
	generative energy in the event of momentary power failure.							6

Note: Even when this parameter is set, the particular load conditions may cause the motor to coast. In this case, use the auto-restart function along with this parameter function.

Motor speed

★The time for which the operation of the motor can be continued depends on the machine inertia and load conditions. Before using this function, therefore, perform verification tests.

★Use with the retry function allows the motor to be restarted automatically without being brought to an abnormal stop.

★The operation continuing time is about

Approx. 100ms	100ms when regenerative power ride-
	through control is enabled (		= 1).
