Range Explanation
High Byte
0..3 16 Bit Word.
Bit 0 : Low = Stop, High = Run Enable
Bit 1 : Low = No Function, High = Fault Reset
Bit 2 : Low = Decel Ramp 1 (P1‐04), High = Decel Ramp 2
0..20000 Setpoint frequency x10, e.g. 100 = 10.0Hz
0..2000 Torque Setpoint %x10, e.g. 1000 = 100.0%
Ramp time in seconds x 10, e.g. 250 = 25 seconds
Low Byte = Drive Error Code, see table below
High Byte = Drive Status as follows :‐
0 : Drive Stopped
1: Drive Running
2: Drive Tripped
0..20000 Output frequency in Hz x10, e.g. 100 = 10.0Hz
0..6000 Output Motor Current in Amps x10, e.g. 10 = 1.0 Amps
0..2000 Output Motor Torque %x10, e.g. 1000 = 100.0%
0..3200 Output Motor Power in kW x10, e.g. 100 = 10.0kW
0..15 Indicates the status of the 4 digital inputs
Lowest Bit = 1 Input 1
0..1000 Analog input % of full scale x10, e.g. 1000 = 100%
0..1000 Analog input % of full scale x10, e.g. 1000 = 100%
0..1000 DC Bus Voltage in Volts
0..100 Drive heatsink temperature in ºC
0..660 L1 – L2 Supply Voltage
0..660 L2 – L3 Supply Voltage
0..660 L3 – L1 Supply Voltage
Internal Speed Value
0..1000 Energy consumed in kWh
0..65535 Energy consumed in MWh
