Use this function to select the desired direction of motor rotation when looking at the motor shaft end from the drive side.
• clockwise
• counterclockwise
The displayed direction of rotation applies when the digital inputs for reversing the rotation are not active.

6.20 "Skip band"

Use this function to select a skip band within the range from user-set minimum speed to user-set maximum speed, if continuous operation is
not required. The upper and lower speeds are stated in percentage of rated speed.
The purpose of the skip band is to avoid certain speeds which may cause noise or vibrations. If no skip band is required, select "-".

6.21 "Standstill heating"

Use this function to avoid condensation in humid environments.
When you set the function to Active and the product is in operating mode Stop, a low AC voltage is applied to the motor windings. The
voltage is not high enough to make the motor rotate, but ensures that sufficient heat is generated to avoid condensation in the product,
including the electronic parts in the drive.
Remember to remove the drain plugs and fit a cover over the product.
