Auto-tuning steps for "Static auto-tuning"
It is recommended to use Rotational tuning process while commissioning, but
in some cases this is not possible because motor-pump group is already con‐
nected to the hydraulic circuit. So if forced to use static auto-tuning it needs
to be checked, that motor inertia defined by C1.13 / C1.14 equals that of the
actual motor.
- > The motor inertia, which is preconfigured by default, is suiting to the pow‐
er class of the drive. This value can greatly vary on the construction of the
motor, but in practice only one default value can be set. So the motor inertia
value is subjected to be changed according to the motor used in the applica‐
tion if it’s not matching to the default value
CAUTION
Danger of mechanic destruction of the pump during rotation if it is mounted
with motor!
