Catch On Fly FLr Allows a smooth restart after:

• Brief loss of input power

Yes - No No

• Fault reset or automatic restart

• Freewheel stop or DC injection braking with a logic input

• Momentary interruption of the drive controller output

If relay R2 is assigned to the Brake Logic function, FLr will always be set to

No.

Cont. Stop StP Controlled stop upon loss of input phase. This

function is only operational if the IPL parameter

(Input Phase Loss) is set to No. If IPL is set to

No - NMS -

FRP

Yes, leave StP set to No. Possible choices:

• No: loss of input phase causes drive controller to trip

• NMS: Maintenance of DC bus: the DC bus is kept energized by

regenerating the kinetic energy from the machine inertia, until the USF

(Undervoltage) fault appears.

• FRP: Following a ramp: deceleration following the programmed ramp,

either dEC or dE2 until the motor stops or the USF (Undervoltage) fault

appears. This operation is not available on the ATV58•U09M2, U18M2,

U29M2 and U41M2.

RampNotFoll Sdd This function can be accessed if feedback via tachogenerator or

pulse generator is programmed. When enabled, it is used to lock

the speed controller if a speed error is detected (difference

between the stator frequency and the measured speed).

Yes / No options.
