Recommended 1336 IMPACT Drive Grounding
To ground your 1336 IMPACT drive, you need to:
1. Connect the drive to the system ground at the power ground (PE)
terminal provided on the power terminal block (TB1).
2. Define the paths through which the high frequency ground
currents flow.
3. Connect the ground conductor of the motor cable (drive end)
directly to the drive ground terminal, not to the enclosure bus bar.
4. Ground the encoder connections (if you are using an encoder).
5. Ground the control and signal wiring.
6. Connect the TE terminal block.
7. Connect the ground bus to adjacent building steel or a floor
ground loop.
8. Solidly ground the RFI filter, if you need to use one.
These steps are explained in greater detail in the following sections.
