6.3 Plug connectors
(
Stop!
¯ Tighten the coupling ring of the connector.
¯ If plugs without SpeedTec bayonet nut connectors are used, the
connector boxes for the power / encoder / fan connections must be
secured by O−rings if loadings by vibration occur:
– M17 connector box with O−ring 15 x 1.3 mm
– M23 connector box with O−ring 18 x 1.5 mm
– M40 connector box with O−ring 27 x 4.0 mm
¯ Never disconnect plugs when voltage is being applied! Otherwise, the
plugs could be destroyed! Inhibit the controller before disconnecting
the plugs!
When connecting the cable socket to the motor connector, make sure that the aids to
orientation (pos. 1) are facing each other. Only then, trouble−free operation is ensured.
