I've got a machine tool that runs a servo, along with a variable speed drill. The servo input card is being damaged when the VFD fires up from time to time. It's always when the VFD starts.
Also got a moving piece that runs VFD (480 V) lines in parallel with encoder lines.
Besides not doing this (running in parallel over long distances) what can I do to minimize noise from the VFD getting into the low voltage encoder cabling?
