52ACS 400 User’s ManualApplication Macro PremagnetiseThis macro is intended for those applications where the drive must start very quickly. Building up theflux in the motor always takes time. With the Premagnetise Macro, this delay can be eliminated.The value of parameter 9902 is 7 ( PREMAGN).*Constant speed selection: 0 = open, 1 = connectedPremagnetise parameter values:Input signals Output signals U/I Jumper J1• 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)DI3 DI4 Output0 0 Reference through AI11 0 Constant speed 1 (1202)0 1 Constant speed 2 (1203)1 1 Constant speed 3 (1204)1001 EXT 1 COMMANDS 2 (DI1,2) 1402 RELAY OUTPUT 2 2 (RUN)1002 EXT 2 COMMANDS 0 (NOT SEL) 1503 AO CONTENT MAX 50 Hz1003 DIRECTION 3 (REQUEST) 1601 RUN ENABLE 0 (NOT SEL)1102 EXT1/EXT2 SEL 6 (EXT1) 1604 FAULT RESET SEL 0 (KEYPAD)1103 EXT REF1 SELECT 1 (KEYPAD) 2008 MAXIMUM FREQ 50 Hz1105 EXT REF1 MAX 50 Hz 2105 PREMAGN SEL 5 (DI5)1106 EXT REF2 SELECT 0 (KEYPAD) 2201 ACC/DEC 1/2 SEL 0 (NOT SEL)1201 CONST SPEED SEL 7 (DI3,4) 4001 PID GAIN 1.01401 RELAY OUTPUT 1 3 (FAULT (-1)) 4002 PID INTEG TIME 60 s$, $, SCRAI1AGND+10VAI2AGNDAO1AGND+24VDCOM1DI1DI2DI3DI4DI5DCOM2RO1CRO1ARO1BRO2CRO2BmAExternal Reference 1: 0...10 V <=> 0...50 HzReference voltage 10 VDCNot usedOutput frequency 0...20 mA <=> 0...50 Hz+24 VDCStart/Stop: Active to start ACS 400Fwd/Rev: Activate to reverse rotationConstant Speed selection*Constant Speed selection*Premagnetise: Activate to start premagnetisingRelay output 1, programmableDefault: Fault => 17 connected to 18Relay output 2, programmableDefault: Running => 20 connected to 22RO2A0 - 10 V0(4) - 20 mA
