IMPULSE•G+ Mini Advanced Instruction Manual – March 2014

Automatic Slip Compensation
As the load becomes larger, the motor speed is reduced and the motor slip increases. The slip
compensation function keeps the motor speed constant under varying load conditions. D02.01 sets
the slip compensation gain. When the gain is “1.0”, the output frequency is increased by 1% of the
E01.06 setting at rated current. A setting of “0.0” results in no slip compensation.
Torque Compensation
The motor torque requirement changes according to load conditions. Full-range automatic torque
boost adjusts the voltage of the V/f pattern according to the required torque. The IMPULSE•G+
Mini automatically adjusts the voltage during constant-speed operation as well as during
acceleration. See below, Figure 5-21.
Figure 5-21: Torque Characteristics
The required torque is calculated by the inverter. This ensures trip-less operation and power savings.
