<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.

LCD Display
Displays the flow rate based on the pulse input frequency or the
analog voltage (flow rate input) and parameters P6-01 and
Flow Rate
P6-04.
A 2-second first order filter will be applied to this monitor.
Displays the recorded volume from the flow meter (pulse input
Volume * 1000000
or analog voltage).
Total volume is calculated as follows:
Volume * 1000 Total Volume = (U1-84 * 1000000) + (U1-85 * 1000) + U1-86
+ U1-87
Volume * 1
Volume * 0.0001
Displays the PID Setpoint.
Pump Setpoint
Displays the PID Feedback.
Pump Feedback
Displays Pump Running Status.
Pump Status
Displays the total absolute Setpoint Compensation.
Total SP Comp.
Displays the absolute value of the output frequency (U1-02)
Motor Speed
converted to RPM.
Displays the amount of water above the water level sensor.
Water Level
Displays the amount of suction pressure.
Suction Pressure
The Anti-No-Flow reduces the output frequency when this
ANF Timer
value reaches the P2-24 setting.
LCD Display
Displays the current fault.
Current Fault
Displays the previous fault.
Last Fault
Displays the frequency reference at the previous fault.
