GS1 and GS2 VFD Reference

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.

1. Disconnect power using the approved lockout/tagout procedure.
2. Before removing the old drive, label each wire and record its terminal location.
3. Install the replacement drive and reconnect every wire to its recorded terminal.
4. On a GS1 drive, place the DIP switch in the up position.

• On a GS2 drive, place all three DIP switches in the up position.

1. Restore power through the approved startup procedure.
2. Set the following parameters: 09-00 = <Axis number> (See label DRxx)
   For example if the DR Label is DR20 you would put 20 into 9-00.
   The axis number is the number that follows the DR prefix.
   Component-label prefixes include DR for drive, FU for fuse, and V for VC1.
   Locate the component label beside the drive and use its DR number as the axis number.
   

Set parameter 9-01 to 2.

Set parameter 9-02 to 4.

GS1 Factory Reset Set parameter 9-08 to 99.

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.
