Flow Rate Flow Rate
Displays the flow rate based on the pulse input frequency or the
analog voltage (flow rate input) and parameters P6-01 and
P6-04.
A 2-second first order filter will be applied to this monitor.

Volume * 1000000
Displays the recorded volume from the flow meter (pulse input
or analog voltage).
Total volume is calculated as follows:
Total Volume = (U1-84 * 1000000) + (U1-85 * 1000) + U1-86
+ U1-87

<1> The number of decimal places in the parameter value depends on the drive model and the ND selection. This value has two decimal places (0.01
A) if the drive is set for a maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 A) if the maximum applicable
motor capacity is higher than 11 kW.
<2> When reading the value of this monitor via MEMOBUS/Modbus, a value of 8192 is equal to 100% of the drive rated output current.
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<4> The display resolution depends on the ND selection. This value has two decimal places (0.01 kW) if the drive is set for a maximum applicable
motor capacity up to and including 11 kW, and one decimal place (0.1 kW) if the maximum applicable motor capacity is higher than 11 kW.
