KEB COMBIVERT F6 - Cable Cross-Sections; Cable Cross-Sections 400 V Class; Cable Cross-Section 690 V Class; Table 22: Cable Cross-Sections 400 V Class

6.4.6 Cable cross-sections
The motor cable cross-section depends
• on the form of the output current (e.g. non-sinusoidal)
• on the real effective value of the motor current.
• on the cable length.
• on the type of used cable.
• on ambient conditions such as bundling and temperature.
