If temperatures are too high, the motorshould be equipped with an external fanP11.7 109 X — Torque increase 00 Deactivated1 EnabledAutomatic increase of the output voltage (Boost) with anincreased load and low speed (for example, heavy starting duty)Caution: A high torque at low speed leads to a high thermalload on the motorNote: If temperatures are too high, the motor should be fittedwith an external fanP11.8 600 X — Control mode 00 Frequency control (V/Hz)The setpoint entry controls the output frequency of thefrequency inverter (resolution of the output frequency =0.01 Hz)Note: In this mode, multiple motors, with varying outputs, canbe connected in parallel in the output of the frequency inverter1 Speed control with slip compensation (vector)The setpoint entry controls the motor speed depending on theload torque (calculation by motor model)Note: In this mode, only one motor with the assigned power(current) may connected in the output of the frequency inverterNote: The speed control requires a precise electricalreproduction of the connected motor. The motor ratingsplate information must be set in the parameter group P7 in thiscase
