288 Parameters
97.15 Motor model
temperature
adaptation
Selects whether the temperature-dependent parameters
(such as stator or rotor resistance) of the motor model
adapt to actual (measured or estimated) temperature or
not.
See parameter group 35 Motor thermal protection for
selection of temperature measurement sources.
Disabled
Disabled Temperature adaptation of motor model disabled. 0
Estimated temperature Estimated temperature (35.01 Motor estimated
temperature) used for adaptation of motor model.
1
97.16 Stator temperature
factor
Tunes the motor temperature dependence of stator
parameters (stator resistance).
50
0…200 % Tuning factor.
97.17 Rotor temperature
factor
Tunes the motor temperature dependence of rotor
parameters (eg. rotor resistance).
100
0…200 % Tuning factor.
97.20 U/F ratio Selects the form for the U/f (voltage to frequency) ratio
below field weakening point. For scalar control only.
Disabled
Linear Linear ratio for constant torque applications. 0
Squared Squared ratio for centrifugal pump and fan applications.
With squared U/f ratio the noise level is lower for most
operating frequencies. Not recommended for permanent
magnet motors.
1
97.33 Speed estimate filter
time
Defines a filtering time for estimated speed. 5.00
0.00...100.00 ms Filtering time for estimated speed. 1 = 1 ms
97.48 Udc stabilizer Enables or disables the DC bus voltage stabilizer. Disabled
Disabled DC bus voltage stabilizer disabled. 0
Enabled min DC bus voltage stabilizer enabled, minimum stabilization. 50
Enabled mild DC bus voltage stabilizer enabled, mild stabilization. 100
Enabled medium DC bus voltage stabilizer enabled, medium stabilization. 300
Enabled strong DC bus voltage stabilizer enabled, strong stabilization. 500
Enabled max DC bus voltage stabilizer enabled, maximum stabilization. 800
97.49 Slip gain for scalar Sets gain for slip compensation (in %) while drive is
operating in scalar control mode.
• A squirrel-cage motor slips under load. Increasing the
frequency as the motor torque increases compensates
for the slip.
• Requires parameter 99.04 Motor control mode =
Scalar.
0 = No slip compensation.
1...200 = Increasing slip compensation. 100% means full
slip compensation according to parameters 99.08 Motor
nominal frequency and 99.09 Motor nominal speed.
0
0...200 % Slip compensation in %. 1 = 1%
No. Name/Value Description Default
