This output is input to the Watt hour meter or PLC through a 200 ms pulse signal. The drive triggers a 200 ms
pulse each time the KWh data is at the value set in H2-06. This parameter sets the kWh unit for each pulse output.

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.
