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.
