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.
Input signals
• Start, stop and direction (DI1,2)
• Analogue reference (AI1)
• Preset speed selection (DI3,4)
• Premagnetise (DI5)
