Edwards nEXT200200 - Temperature Readings; Link Parameter Readings; Measured Motor Speed

6.3.5 Temperature readings
The t
emperatures of the pump motor and the internal electronics of the pump can be
monitored. Send the query that follows:
Command ? V 8 5 9 cr
The reply is as follows:
Reply = V 8 5 9 sp d d d ; d d d cr
Here:
▪ rst number is the motor temperature
▪ second number the internal controller temperature, all measured in °C.
6.3.6 Link parameter readings
The parameters that follows can be monitored:
▪ internal voltage
▪ current and motor power of the pump.
Send the query that follows:
Command ? V 8 6 0 cr
The reply is as follows:
Reply = V 8 6 0 sp d d d ; d d d ; d d d d d cr
Here:
▪ rst number sho
ws the voltage (measured in 0.1 Volts - i.e. divide the number by
10 to get the answer in Volts)
▪ second number shows the current (measured in 0.1 Amps)
▪ third number shows the motor power (measured in 0.1 W
as).
6.3.7 Measured motor speed
The measured rotaonal speed of the motor in the pump can be monitored.
Send the query that follows:
Command ? V 8 5 2 cr
The reply as as follows (where r
st returned number shows the motor rotaonal speed
in revoluons per second (Hz)):
Reply = V 8 5 2 sp d d d d ; h h h h h h h h cr
Note:
The sec
ond return number is a 32 ‑ bit system status word (set of 8 hexadecimal
characters) which is useful for fault nding. Refer to Decoding system status words on
page 83 to decode the system status word.
