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.
*Constant speed selection: 0 = open, 1 = connected
Premagnetise parameter values:

• Start, stop and direction (DI1,2) • An. output AO: Frequency
• Analogue reference (AI1) • Relay output 1: Fault
• Preset speed selection (DI3,4) • Relay output 2: Running
• Premagnetise (DI5)
