The reply is as follows:
Reply = v 8 6 5 sp d d d ; d d d ; d d d cr
Here:
▪ first number is the motor temperature
▪ second number is the motor controller temperature
▪ third number is the rotor temperature, all measured in °C.
6.4.6 Monitor 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:
▪ first number shows the link voltage (measured in 0.1 Volts - i.e. divide the number
by 10 to get the answer in Volts)
▪ second number shows the link current (measured in 0.1 Amps)
▪ third number shows the link power (measured in 0.1 Watts).
6.4.7 Monitor measured motor speed
The measured rotational speed of the motor in the pump can be monitored.
Send the query that follows:
Command ? v 8 5 2 cr
The reply is follows (where first returned number shows the motor rotational speed in
revolutions per second (Hz)):
Reply = v 8 5 2 sp d d d d ; h h h h h h h h cr
Note:
The second return number is a 32
‑
bit system status word (set of 8 hexadecimal
characters) which is useful for fault finding. Refer to Fault finding on page 90.
6.5 Mixed parallel and serial operation
In mixed parallel and serial operation the pump can receive commands from serial and
parallel interfaces. Refer to Figure: Logic interface connection - mixed parallel and serial
operation to understand how the commands control the pump. The pump will power up
with ‘None in Control’. From this state a parallel start signal or a serial start command
