172 Parameters
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
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
0 = No slip compensation.
1...200 = Increasing slip compensation. 100% means full slip
compensation according to parameters
0
0...200 %
Slip compensation in %.
1 = 1%
Sets the frequency at which IR compensation (set by
parameter
) 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 %.
