Non Captive Linear Actuator - How to hook it up??


I bought a Non Captive Linear stepper motor from here

its the 25NCLA-B04, I thought it was just a standard stepper motor, but this connection has 6 cables from it being

Yellow Orange Red Black Brown White

All the wiring examples I've seen online only have 5 cables for the stepper motors... am I missing something?

Thanks in advance for any help, greatfully recieved!
