Revision 4	Wiring for Mclennan 34HSX Motor

The C0001 stepper motor used on the G axis of flowlines and on all motors on the router has become obsolete.

A replacement will be available using the same Stuga part number

Old Manufacturer’s number:       SMS343-098-S-FN       

New Manufacturer’s Number:     SMR343-090-L-FN

The new version is mechanically the same.  It’s a rare earth magnet construction (S series was standard magnets) which will provide about 30-40% more torque. The current setting on the drives should be the same too – so no need to adjust drive current in new or existing installations.

The wiring is the only change we need to be aware of – they have the same colours, but (confusingly) they are used for different purposes!
