Parker Inverter AC890PX up to 400kw

The AC890PX is a high power industrial variable frequency drive for AC motors with power ratings of 150-600HP. The packaged VFD includes fuses, disconnect, line reactor, and braking…all that is necessary where a standalone enclosed drive is required.

The AC890PX is a high power variable speed drive for AC motors with power ratings from 150 to 600HP (100 to 400kW). It is a standalone unit provided with all of the standard equipment necessary for new or retrofit applications where a complete enclosed VFD is required. Configuration and start-up of the AC890PX can be performed using the standard operator keypad or from your laptop using DSELite configuration software. The modular design, featuring plug-in inverter phase modules, makes servicing the AC890PX quick and easy.

Safe Torque Off - STO:
  • The AC890PX features Safe Torque Off functionality as standard, offering users protection against unexpected motor start-up in accordance with ISO/EN13849-1 PL-e or SIL3. Two independent STO control channels are implemented in hardware. A fault in one control channel will not affect the other channel’s ability to prevent the drive from starting, i.e. the STO function of the is tolerant to any single fault. It may not be tolerant to an accumulation of faults. This is in keeping with its declared safety ratings. If one or both STO control inputs is requesting the STO function, the drive will not start, even if for example, the drive’s software malfunctions and tries to cause the motor to turn. The STO function is implemented in hardware; it overrides all software activities. The only software involvement is to report STO status to the user via an MMI, serial communications link or user terminal on the AC890 control board as defined by the drive configuration.
