The Parker SSD 890 Series AC Drive is a compact, modular systems drive engineered to control speed and position of open-loop and closed-loop.
The 890 range is designed to control standard 3-phase ac induction motors and brushless servo motors. There are three main types of 890 :
890CS Common Bus Supply
The Common Bus Supply connects to AC and provides DC to the Common Bus Drive (s) via busbars.
890CD Common Bus Drive
The Common Bus Drive (s) receives DC from the Common Bus Supply. It provides control for the motor.
The figure shows a Frame B Common Bus Supply linked to three Frame B Common Bus Drives.
890SD Standalone Drive
The Standalone Drive is AC supplied and provides control for the motor. The figure shows a Frame B Standalone Drive.
The 890 is fitted with the 6511 Keypad.
It provides Local control of the 890. For example, you can start and stop the motor and check on diagnostic information. The keypad can also be used to change parameters values on the 890CD and 890SD units. The 6511 keypad fits to the front of the 890. You can also remote-mount the 6511 keypad up to 3 metres away. Another option is to remote-mount a 6901 keypad (as used on our larger 690+ drives). The 6901 keypad provides plain language programming on its larger display, and it also has the ability to upload, store and download parameters. For remote-mounting, you’ll need the correct Remote Mounting Kit.
