Direction Of Rotation - Siemens SIMOTICS 1LE8 Operating Instructions Manual

Motors which are exposed to a wide temperature fluctuation environment are susceptible to
condensation formation, hence it is strongly recommended to add a anti-condensation
heater (option code: Q04). The terminal for the DE heater is 1HE1-1HE2.

Direction of rotation

The standard motors are suitable for clockwise and counter-clockwise rotation.
For defined directions of rotation (direction of rotation arrow), appropriately connect the line
power cables.
• If you connect the line cables with phase sequence L1, L2, L3 at U, V, W or according to
• If you interchange 2 connections, e.g. L1, L2, L3 at V, U, W or according to NEMA at
