First the machine will need to have a spindle encoder on the spindle motor and the spindle drive will need to be a vector drive. There are a couple of ways to find out:
Make a physical inspection at the motor. First remove any cover or filters on top of the spindle motor. The encoder will be installed on the end of the spindle motor shaft.
At the spindle drive, the encoder cable has a square 3x3, 9 pin connector on the end, the wire colors will typically be blue, black, green, red, yellow and brown.
Note, some spindle drives will use the encoder but are not capable of rigid tapping and would need to be updated to a CALAMP-7 vector drive. These are typically the Mitsubishi drives.
If the spindle drive is a Baldor, Sweo, GTK, AMC or Yaskawa, then it is probably a vector drive capable of rigid tapping. If not then update to a CALAMP-7 .
Next a cable from the vector drive to the spindle card will be needed. The 527F rigid tapping is an option to enable the spindle card to support the rigid tapping G-codes. Then a couple parameters will need to be configured with an indicator and SVT-0077 service tool.
