Parker 890 - Introduction; About this Quickstart

Page 5
Introduction
The 890 Common Bus units are designed for speed control of standard ac 3-phase motors. The
common bus scheme consists of one 890CS (Common Bus Supply) and one or more 890CD
(Common Bus Drives).
3-phase power is supplied to the 890CS. Power (DC) is bussed from the 890CS to all 890CDs using
the SSD_Rail busbar system. A motor is connected to each 890CD unit.
• Control the system remotely using configurable analogue and digital inputs and outputs.
• Control the 890CD locally using the 6511 Keypad.
• Use the Design System Explorer Configuration Tool (DSE 890) to give access to 890CD
parameters, diagnostic messages, trip settings and application programming.
• Fit Options to the 890CD to give serial communications and closed loop speed control.
IMPORTANT
Motors used must be suitable for Inverter duty.
About this QuickStart
This QuickStart will:
• Familiarise you with the terminals and operation of the unit.
• Provide
*basic installation details and a quick set-up procedure.

* Because the 890 is a system product and we have no knowledge of your application, we detail
the quickest way to power-up the drive using a simple earthing scheme with minimal control
wiring. Refer to the full Engineering Reference Manual for items not covered in this QuickStart.
Provided with every 890 unit is a:
z Quickstart
z Compact disk containing the Engineering Reference Manual and DSE Configuration Tool
