Application Macro Premagnetize - ABB ACS 400 User Manual

Application Macro Premagnetize

This macro is intended for those applications where the drive must start very quickly. Building up the
flux in the motor always takes time. Using the Premagnetize Macro will minimize this delay.
The value of parameter 9902 is 7 (
Input signals
• Start, stop and direction
(DI1,2)
• Analog reference (AI1)
• Preset speed selection (DI3,4)
• Premagnetize (DI5)
*Constant speed selection: 0 = open, 1 = connected
