8.2 Additional parameter information
Due to its user-friendliness and simplicity of use, most
parameters of the RSI only require a basic description
which is given in the parameter tables in chapter
8.1 Application parameter lists.
In this chapter, you will find additional information on
certain most advanced parameters of the RSI. Should
you not find the information you need contact your
distributor.
8.2.1 Motor Control
P3.1.1.2 Motor Nom Freq
When this parameter is changed,
parameters P3.1.4.2 and P3.1.4.3 will be
automatically initialized depending on the
selected motor type. See the second table
in the section P3.1.2.2, Motor type.
P3.1.2.1 Control mode
Selection
number
Selection name Description
0 U/f control (open loop)
Drive frequency reference is set to output frequency without slip
compensation. Motor actual speed is finally defined by motor load.
1
Speed control (open
loop)
Drive frequency reference is set to motor speed reference. The motor
speed remains the same regardless of motor load. Slip is compensated.
P3.1.2.2 Motor type
This parameter defines the used motor type.
Selection
number
Selection name Description
0 Induction motor (IM) Select if an induction motor is used.
1
Permanent Magnet Synchronous
Motor (PMSM)
Select if a permanent magnet synchronous motor is used.
When this parameter is changed, parameters
P3.1.4.2 and P3.1.4.3 will be automatically initialized
according to the selected motor type.
See the table below for the initialization values:
Parameter Induction Motor (IM)
Permanent Magnet Synchronous Motor
(PMSM)
P3.1.4.2
(Field WeakngPnt)
Motor nominal frequency Internally calculated
P3.1.4.3
(Voltage at FWP)
100,0 % Internally calculated
P3.1.2.4 Identification
The automatic motor identification calculates or
measures the motor parameters that are needed for
optimum motor and speed control.
Identification Run is a part of tuning the motor and the
drive specific parameters. It is a tool for
commissioning and service of the drive with the aim
to find as good parameter values as possible for most
drives.
