Warning
Prior to performing connection work, always first make sure that the supply voltage is swit-
ched off.
With the supply voltage switched off, hazardous voltages are present at the mains and motor
connections. Under no circumstances may these connection be touched in the ON condition;
otherwise, loss of life or severe personal injury could be the consequence.
Mains connection
S The device must be connected via an external fuse.
Fuse: K6A for 1 axis
K10A for max. 2 axes
S If the transformer possesses a shielded winding, this should be connected with low inducti-
vity to PE.
S Ground the transformer on the secondary side.
Connecting the motor–end cables
S To connect the cables, remove the terminal box cover (3 screws).
S Use the cable with the order no. 6FX6 002-5AA51-.....
S On the drive end, connect the cable shield to the housing such that an electrical connec-
tion is provided via the appropriate strain relief clamp and clamp the braided shield to PE.
S On the motor side, braid the shield, provided it with a cable shoe and clamp it to the groun-
ding screw.
Pulse interface
S To connect the drive pulse interface to the SINUMERIK 802S, use the preassembled ca-
ble, order no.6FX6 002-3BA31-1xx0.
S On the drive side, connect the cable shield to the housing such that an electrical connec-
tion is provided via the appropriate strain relief clamp.
24V signal interface
S To evaluate the 24 V high-side signals “Zero Phase” (ZPM) and/or “Drive ready” (RDY) in
the CNC, then connect a 24 V voltage (PELV) to the +24 V and 24 V GND terminals.
