ACS55 Micro drive, Single Phase Input variable speed drive (VSD)
An easy to use range of drives designed specifically for the control of low-power motors which do not require the control sophistication of more complex drive units, designed to give the benefits of variable control to users of simple motor starters. Easy to set up, programme and control the motor speed when using the optional potentiometer unit (stock no 493-1059)
The motor control is scalar control, so is suitable for simple applications without the need for highly accurate speed or torque control. Like fans, pumps, simple conveyors and simple machines. The simple interface is designed to introduce users of DOL starters to the advantages of variable speed.
No programming required, easy and descriptive interface used to set up the motor control All drive set-up is done using the 3 panel potentiometers, including motor nominal current 8 dip switches for other parameters including nominal motor frequency, load torque type (for example, pump/fan or constant torque), jog, AI offset (4-20 mA) and auto reset Possible to access additional parameters via a PC tool (optional), the PC tool also allows programming with no power connected to the drive module Fault and status indication LEDs Adjustable switching frequency (for low noise) Accel and Decel ramp rates, fixed frequencies available to program Built-in EMC filter, suitable for domestic networks As it is a VSD, motor protection is on-board, overcurrent, overvoltage, overloads all included Removable mounting clip for DIN Rail or wall mounting from either the rear or side of the drive. Please see the data sheets for dimensions etc. Protection rating IP20
Benefits
ABB ACS55 drives bring several benefits: Improves motor speed control compared to DOL Easy migration for users of simple motor starters Helps to eliminate starting and stopping problems May be networked with other automation equipment (via I/O) Load compensation features Sophisticated motor protection and control Single phase supply controlling a 3 phase motor
Note
Motors may require de-rating when used in conjunction with motor speed controllers, as their cooling fans may not provide sufficient cooling when running slower, please contact ABB if help is required.
Approvals
CE, C-Tick approvals, UL, cUL, GOST R and RoHS compliant
