How to Upload and Download KEB Drive Parameters

One of the more useful features of our drives is the ability to upload and download KEB drive parameters. You can do this using our COMBIVIS 6 automation software. KEB VFDs offer exceptional motor control with a vast amount of parameter options to fine-tune your application to run as smoothly and efficiently as possible. You can easily save parameter lists to a computer as a backup file or use a previously saved file to program a new or existing drive. The upload and download procedures embedded in this blog are also available in our COMBIVIS 6 Tutorials playlist on our KEB America YouTube channel.

Cables to Connect the KEB Drive to a Computer

There are a few things you will need to connect your computer to a KEB device. You cannot use an off-the-shelf USB to serial cable to connect. See the part numbers for each type of cable in the list below: 

• KEB USB-to-serial adapter: 

  • Part number: 0058060-0040 (11-15-2033) USB SERIAL CONVERTER
    This connects to PC via USB and direct to the VFD where the operator connects.

• RJ45 adapter: 

  • Part number: 00F50C0-0020 (11-15-2022) CABLE – HSP5 ADAPTER RJ45 to DB9
    This is the adapter cable to connect from USB Converter to the service port of the Keypad 

• Combivis cable (DIN 66019II – RS-232 cable):

  • Part number: 0058025-001D (11-15-0017) CABLE – PC/INVERTER
    This cable can only be used with a serial interface keypad, it cannot be connected direct to the VFD or to the Service port of the Keypad. Damage to the PC will occur if connected improperly because the VFD uses 24V logic. 

• USB-to-serial adapter with FTDI chipset:
  • Part number: 0000000-7938
