Chapter 12 - ACS 6000 Final Tuning
Note: Before the coupling test can be started, the no-load run must be
properly carried out.
If the motor is equipped with speed encoder, the recommendation is
also to take recordings from the speed actual signal while the motor is
still uncuopled.
After the motor can be run up to maximum speed and down to minimum
speed without problems, the driven equipment can be connected.
Open the main circuit breaker and ground the converter before
connecting the driven equipment. Make sure that the driven equipment
is ready for speeding up.
12.1 Mechanical Heat Run
After mechanics are connected, some mechanics manufacturer require
mechanical heat run. In mechanical heat run the speed is increased
step by step to maximum during few hours and at the same time
bearing temperatures etc. are measured.
Note: After motor is coupled and run with driven equipment, all the
interlockings from automation systems has to be in operation. These
interlocks should stop the drive if there is lack of lubrication or other
critical function needed to run mechanics. Most commonly fast stop
signal is used for this purpose.
12.2 Final Tuning
It is assumed in this chapter, that checking and possible tuning is done
on-line during the loading conditions, which are defined by the process
(during normal operation). Measures must only be taken if unwanted
operation of the drive is detected.
See ACS 6000AD TC SW (Torque Controller Software) commissioning
manual for details.
See alsoChapter 13 - Speed Controller Tuning section 13.2 for final
tuning of speed controller.
