Type = Standby parameters can only be changed when motor is standby (not running).
Type = Stby/Run parameters can be changed in both standby and run.
Type = Read
parameters are read-only.

Value for indicative purpose only as measurement has limited accuracy.
5.6 Select
application
First time powered up after installation, or after performing a factory reset of parameters, the installer will be
prompted to select application type for the inverter. The purpose of selecting application is to preset acceleration
and deceleration ramps to a value suitable for the application in question. Please note that the preset values are a
merely suggested general values. Depending on other operating conditions, the installer may have to further adjust
the accel/decel ramps.
Application
Description
Pump
Set acceleration and deceleration ramps suitable for general pump applications
Ventilation / other
Set acceleration and deceleration ramps suitable for ventilation fan applications
OEM vacuum pump
To be used
only
with OEM vacuum pump application
5.7 Autotuning and motor parameters
There are three alternatives for autotuning the motor parameters: Full tuning, Basic tuning or Calculated tuning. Full
tuning is preferred whenever possible.
Before running autotuning, the nominal motor data has to be entered. It consists of parameters
P-nom, U-Nom,
f-Nom, N-Nom, I-Nom
and
cos
. These are shown on the motor plate and must be entered according to the
connection used; i.e. Y (star) or D (delta), including any possible 50 / 60Hz option for the motor. The default
nominal data settings as supplied are shown in Table 11.
To achieve optimal motor control, the inverter must have a correct set of parameters
R-stat, R-rot, L-main, Sigma,
I-magn
and
I-limit
. The autotuning functionality measures and calculates these motor parameters, taking into
account the cables, etc. between inverter and motor, and ensures best possible control of the motor. Autotuning
shall
always
be performed, even if a standard motor is used.
