Application Macro Premagnetise - ABB ACS 140 Programming Manual

Application Macro Premagnetise

This macro is intended for those applications where the drive must start very
quickly. Building up the flux in the motor always takes time. With the
Premagnetise Macro, this delay can be eliminated.
The value of parameter 9902 is 7.
