2.11.1 Phase Converters
For those machines that will be run with a phase converter it is recommended that it is a rotary
type rather than a static phase converters. Rotary phase converters allow for varying loads in
the system. The electrical load on the machine will vary based on the type of cut taken. Static
phase converters can only be used on machines with a non-varying load. The phase converter
for the K mill machines must be rated at a minimum of 5 KVA for the K2 and K3 and 7 KVA for
K4.
2.11.2 Flange Disconnect/Transformer (Optional)
The Flange Disconnect Option eliminates the need for the user to provide a power disconnect
for the machine on their own, while the Transformer Option allows the user to provide one
power source to the machine. Note: This option is not available to machine fitted with
the Spindle Control Option.
