Motor cooling:
• : Natural cooling
• : Forced-air cooling
• : Liquid cooling
• : Without fan
Select the appropriate application:
• : In all applications that do not 󹪝t the other setting options.
• : Applications involving pumps and fans
• : Applications with short ramp-up and ramp-down times.
• : Applications involving pumps and fans with optimized e󹪟ciency. The setting
only makes sense for steady-state operation with slow speed changes. We recommend
setting if load surges during operation cannot be ruled out.
Select the control mode:
• : U/f control with linear characteristic
• : Flux current control (FCC)
• : U/f control with square-law characteristic
