P15.4 – I3 Type:
Description:
Read Only
The RMS current on phase L3.
Range: Modbus Decimal Value: Default:
0A – 10,000A linear scale (1 = 1mA)
Current (A) = (Value / 1000)
0A
Modbus Address: Modbus Format:
33540/33541 ( 8304/8305 hex ) 32-bit unsigned
Touchscreen Menu Path:
Home → Monitor → I3
P15.5 – Current Irms Type:
Description:
Read Only
The RMS motor current.
• This is the maximum of the 3 phases.
• This value is used for the overload and power calculations.
Range: Modbus Decimal Value: Default:
0A – 10,000A linear scale (1 = 1mA)
Current (A) = (Value / 1000)
0A
Modbus Address: Modbus Format:
32896/32897 ( 8080/8081 hex ) 32-bit unsigned
Touchscreen Menu Path:
Home → Monitor → Current Irms
P15.6 – Vrms (Approx) Type:
Description:
Read Only
The RMS 3-phase supply voltage.
• This is the average of the 3 phases.
• This value is used for power calculations.
• This value is derived internally. If a higher level of accuracy is required, a “Fixed Voltage” value
can be used.
• The internally measured voltage is not an accurate method of obtaining a voltage reading. This
voltage reading can have and error up to 35% if the starter and motor is unloaded or lightly
loaded.
Range: Modbus Decimal Value: Default:
0V – 500V linear scale ( 1 = 1 V ) 0V
Modbus Address: Modbus Format:
32960 ( 80C0 hex ) 16-bit unsigned
Touchscreen Menu Path:
Home → Monitor → Vrms (Approx)
P15.7 – Real Power Factor Type:
Description:
Read Only
The actual power factor.
Range: Modbus Decimal Value: Default:
0 – 1 linear scale ( 1 = 0.001 ) 0
Modbus Address: Modbus Format:
33024 ( 8100 hex ) 16-bit unsigned
Touchscreen Menu Path:
Home → Monitor → Real Power Factor
