4 MULTI-STEP SPEED CONTROL APPLICATION4.1 INTRODUCTIONSelect the Multi-step Speed Control Application in menu M6 on page S6.2.The Multi-step Speed Control Application can be used in applications where fixed speeds areneeded. In total, 15 + 2 different speeds can be programmed: one basic speed, 15 multi-stepspeeds and one jogging speed. The speed steps are selected with digital signals DIN3, DIN4,DIN5 and DIN6. If jogging speed is used, DIN3 can be programmed from fault reset to joggingspeed select.The basic speed reference can be either voltage or current signal via analogue inputterminals (2/ 3 or 4/5). The other one of the analogue inputs can be programmed for otherpurposes.• All outputs are freely programmable.Additional functions:• Programmable Start/Stop and Reverse signal logic• Reference scaling• One frequency limit supervision• Second ramps and S-shape ramp programming• Programmable start and stop functions• DC-brake at stop• One prohibit frequency area• Programmable U/f curve and switching frequency• Autorestart• Motor thermal and stall protection: Programmable action; off, warning, faultThe parameters of the Multi-Step Speed Control Application are explained in Chapter 9Parameter descriptions of this manual. The explanations are arranged according to theindividual ID number of the parameter.MULTI-STEP SPEED CONTROL APPLICATION VACON · 63LOCAL CONTACTS: HTTP://DRIVES.DANFOSS.COM/DANFOSS-DRIVES/LOCAL-CONTACTS/ 4 |
