ABB Frequency Inverter Drives ACS355

  • Vector control for improved precision, induction or PM motors possible
  • Extensive parameter set, including PID control
  • Dedicated machinery 8-step sequencer (or 16 steps with additional FW – speak to ABB)
  • STO as standard, SIL 3, PLe, connections are behind the keypad (see images)
  • Logical parameter set, accessed by a choice of keypads
  • Control via I/O, or fieldbus interfaces (option)
  • External 24 V option allows the drive control to be powered up without the need for mains
  • Real Time Clock (RTC) when assistant keypad fitted, operations can be triggered using the internal timed functions
  • DC connection, the drive can be connected to a common DC bus – useful in larger machines
  • Multiple mounting configurations: wall or DIN Rail, back or side, IP20 rated
  • Unified height and depth across the sizes makes cabinet design easy (cable trays run parallel)
  • Can be programmed in the box with FlashDrop tool (stock no.621-1329), allowing fast and easy drive set-up and commissioning for volume manufacturing without needing to apply power to the drive
  • The ABB logo clip can also be removed for OEM’s wishing to brand label
  • Please see the data sheets for dimensions etc
  • ABB ACS355 drives bring a number of benefits:
  • Dedicated for machinery applications, to allow easy machine automation
  • Built in Braking chopper as standard, converting kinetic energy to braking power (external resistor required)
  • Sequencer and extended parameters can remove the need for external controllers (PLC’s) thus reducing machine costs
  • Timed functions allow the drive to operate differently at different times of the day (requires assistant keypad)
  • Improves motor speed control compared with vector controller.
  • Choice of keypads to suite the budget
  • May be networked with other automation equipment (via I/O and Fieldbus options)
  • Sophisticated motor protection and control
  • Sophisticated maintenance triggers
  • Single phase supply controlling a 3 phase motor
