6.3.5 Temperature readings
The temper
atures 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 show
s 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 Was).
6.3.7 Measured motor speed
The measured rotaonal 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 rs
t returned number shows the motor rotaonal speed
in revoluons 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 re
turn 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 89 to decode the system status word.
