364 Parameters
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%
97.94 IR comp max
frequency
Sets the frequency at which IR compensation (set by
parameter 97.13 IR compensation) reaches 0 V. The unit is %
of motor nominal frequency.
IR compensation
When enabled, IR compensation provides an extra voltage
boost to the motor at low speeds. Use IR compensation, for
example, in applications that require a high breakaway
torque.
80.0
1.0...200.0 % IR compensation maximum frequency in %. 1 = 1%
98 User motor
parameters
Motor values supplied by the user that are used in the motor
model.
These parameters are useful for non-standard motors, or to
just get more accurate motor control of the motor on site. A
better motor model always improves the shaft performance.
98.01 User motor model
mode
Activates the motor model parameters 98.02…98.12.
Notes:
• Parameter value is automatically set to zero when ID run is
selected by parameter 99.13 ID run requested. The values
of parameters 98.02…98.12 are then updated according to
the motor characteristics identified during the ID run.
• Measurements made directly from the motor terminals
during the ID run are likely to produce slightly different
values than those on a data sheet from a motor
manufacturer.
• This parameter cannot be changed while the drive is
running.
