The direction of motor rotation is changed by switching two motor phases.
4.4.5 Motor Thermal Protection
The electronic thermal relay in the frequency converter has received the UL-approval for single motor protection, when par. F-10 Electronic Overload is set for
Electronic Thermal Overload Trip and par. P-03 Motor Current is set to the rated motor current (see motor name plate).
4.4.6 Motor Insulation
For motor cable lengths the maximum cable length listed in the General
Specifications tables the following motor insulation ratings are recommen-
ded because the peak voltage can be up to twice the DC link voltage, 2.8 times
the mains voltage, due to transmission line effects in the motor cable. If a
motor has lower insulation rating it recommended to use a du/dt or sine wave
filter.
