Application Macro Premagnetise - ABB ACS 160 User 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 (
Input signals
• Start, stop and direction
(DI1,2)
• Analogue reference (AI1)
• Preset speed selection (DI3,4)
• Premagnetise (DI5)
Connection example:
External Reference 1: 0...10 V <=> 0...50 Hz
Output frequency 0...20 mA <=> 0...50 Hz
Premagnetise: Activate to start premagnetising
*Constant speed selection: 0 = open, 1 = connected
