14. Default Power Response and Logic Ride Through
1. On the Power Loss Demo set the DROPOUT TIME selector switch to 1/60, and the MULTIPLIER
thumbwheel to X 2 to create a power interruption time of 33 ms.
2. Start the drive by pressing the button on the HIM, and run the motor at 60 Hz. (use the
speed potentiometer to the right of the drive to get to 60 HZ).
3. If DriveObserver is not already recording, start recording data.
4. Remove input power to the drive for 33ms by pressing the SINGLE SHOT button on the Power
14
Loss Demo module.
5. Using DriveObserver, observe the output frequency and bus voltage during the power interruption.
Also note whether the drive experienced a fault.
6. Repeat the above steps for an interruption of 1.5 seconds (1/2 X 3 on the Power Loss demo
module).
Clear any faults by pressing the button on the drive’s HIM if necessary.
7. Disable the Under Voltage Fault by resetting parameter 238 [Fault Config 1] / bit 1 [UnderVoltage]
to a value of 0. Then, retest with a power interruption for 1.5 seconds.
8. Stop the drive by pressing the button on the drive’s HIM.

Inertia Ride-Through
When a drive, which has been configured for inertia ride through, senses an interruption in incoming
power, it can reduce the output frequency and convert the kinetic energy of the load’s inertia into
electrical energy to maintain the dc bus voltage.
1. Change the value of parameter 184 [Power Loss Mode] to a value of 1 – Decel. This enables
inertia ride through.
2. Enable the Power Loss Fault. Set parameter 238 [Fault Config 1] bit 0 [Power Loss] to a 1.
3. Set the Power Loss demo module to 1/2 X 8 or 4 seconds.
4. Start drive and run the motor at 60 Hz. If DriveObserver has stopped recording, restart it.
5. Remove input power to the drive for 4 seconds by pressing the SINGLE SHOT button on the
Power Loss Demo module. Observe the performance of the drive.
6. Increase the value of parameter 185 [Power Loss Time] from 0.5 seconds to 6 seconds. Repeat
the above steps and observe the performance of the drive.
7. Estimate the inertia ride through time for 60 Hz (1800 RPM).
 Start by calculating the Moment of Inertia (J) of the flywheel.
Mass (m) = 14.5 kg Radius (r) = 0.1524 meters.
J = kgm2.
 Calculate the Stored Energy (W)
Speed (n) = 1800 RPM.
W = watt-seconds.

16.  The average power consumption for the drive and motor is 100 watts. Understand that this
figure includes friction and windage losses in the motor, which vary with motor speed.
16
 Estimate the Ride through Time.
Time (in seconds) = Stored Energy (in watt-seconds) / Average Power Consumed (in watts).
Estimated ride through time =_________________________________.
8. Change the value of parameter 185 [Power Loss Time], so it exceeds the time you calculated in
the last step.
Run the drive in ride through mode and remove power. Measure and compare the time against
your calculated value. Push and hold the INFINITE button to remove input power. On the drive’s
HIM, watch the value of parameter 415 [Encoder Speed]. When the value approaches zero (about
5 Hz), release the drop out button.
Experiment to determine how long you can hold the button without tripping the drive.

17. 17
Flying Start
1. Change the value of parameter 184 [Power Loss Mode] to 0 - Coast.
2. Change the value of parameter 155 [Stop/Brk Mode A] to 0 - Coast.
3. Start the drive and run at 60 Hz. If DriveObserver has stopped recording, restart it.
4. Press the stop button and wait ten seconds. Press the green start button.
Observe the operation of the drive.
5. Stop the drive, then change the value of parameter 169 [Flying Start En] to 1 - Enabled.
6. Start the drive and run at 60 Hz. If DriveObserver has stopped recording, restart it.
7. Press the stop button and wait ten seconds.
8. Press the green start button.
Observe the operation of the drive.
