Installing the STEPDRIVE
3-4
SINUMERIK 802S base line
Start-Up
Mains connection
z
The device must be connected via an external fuse.
Fuse: K6A for 1 axis
K10A for max. 2 axes
z
If the transformer possesses a shielded winding, this should be
connected with low inductivity to PE.
z
Ground the transformer on the secondary side.
Connecting the motor-end cables
z
To connect the cables, remove the terminal box cover (3 screws).
z
Use the cable with the order no. 6FX6 002–5AA51–.....
z
On the drive end, connect the cable shield to the housing such that an
electrical connection is provided via the appropriate strain relief clamp
and clamp the braided shield to PE.
z
On the motor side, braid the shield, provided it with a cable shoe and
clamp it to the grounding screw.
Pulse interface
z
To connect the drive pulse interface to the SINUMERIK 802S base line,
use the preassembled cable, order no.6FX2 002–3AD02–1xx0.
z
On the drive side, connect the cable shield to the housing such that an
electrical connection is provided via the appropriate strain relief clamp.
24V signal interface
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.
