Before You Begin
Safety: Stop the machine, follow the site lockout/tagout procedure, verify that hazardous energy is controlled, and release or secure stored mechanical and pneumatic energy before opening a panel, removing a guard, or adjusting components. Electrical work must be performed by a qualified technician.
Due to the microchip shortage in version 1.60 of the Retro C software Enventek has significate changes in order to support multiple types of VFDs (Variable Frequency Drives). This comes at a time when our main supplier of VFD’s retired a product and new products are hard to get. In 2022 Enventek has worked to keep your Retro C products running by providing support for multiple drives in the same location. Current drives supported are listed below.
New models supported
GS10 Series Drives
GS20 Series Drives
Weg CFW100 Series Drives
Weg CFW300 Series Drives
Weg CFW500 Series Drives
FMX Series Drives
Old models supported
GS1 Series Drives — Retired
GS2 Series Drives — Retired
GS3 Series Drives — Retired
All of these drives may require different mounting and fuses however the wires should stay the same. The Blade motors require STO Modules for safety and all drives require Modbus communication which on the CFW100 and 300 series is an extra module.
Note in order to change drive versions at this time you will need to contact Enventek Technical support.

Confirm the Result
After checking all connections and reinstalling covers, restore power through the approved startup procedure. Confirm that the correct device comes online without a disconnected-drive or communication warning, then test its command, direction, and stopping response in a controlled mode.
If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
