9.  If motor rotation is incorrect in either VFD, bypass, or both modes, have the 

appropriate site personnel take corrective action as follows: 

−  Wrong Rotation in Bypass, Right in VFD Mode – Swap two input 

leads on the main input device of the Electronic Bypass Option.  

−  Wrong Rotation in VFD, Right in Bypass Mode – Swap two input 

leads on the main input device of the Electronic Bypass Option and swap 
two motor leads at the motor overload in the Electronic Bypass Option.  

−  Wrong Rotation in both VFD and Bypass Modes – Swap two motor 

leads at the motor overload in the Electronic Bypass Option.  

Parameter P0010 is the Commissioning Parameter Filter. It allows you to select a 
group of parameters that can be used for quick commissioning, including motor data, 
and motor ramp-up and ramp-down settings. 

It is important to use parameter P0010 to commission the SED2, parameter P0003 to 
select the access level for using parameters, and parameter P0004 to filter the 
parameters according to their functionality. When Commissioning Parameter Filter 
P0010 = 1, it initiates the quick commissioning procedure. 

It is recommended that you use the quick commissioning procedure. However, 
experienced users may commission the equipment without the P0004 filter functions. 

At the end of the quick commissioning procedure, set parameter P3900 = 3. This 
setting performs the necessary motor calculations and sets all remaining parameters 
(those not included in P0010 = 1) to the factory default values. If 3900 is set to a 
value greater than 0, P0010 is automatically reset to 0. (If P0010 = 1, the SED2 
cannot start.) The process of performing motor calculations and setting all 
parameters to factory default values is only possible via quick commissioning.
