unit for each pulse output.
Figure 12.83 Example MFDO when Configured for Watt Hours
Note:
• When the power value is a negative value (regenerative state), the drive does not count Watt hours.
• When the control power supply to the drive is operating, the drive will keep the Watt hours. If a momentary power loss causes the drive
to lose control power, the Watt hour count will reset.
