SIB Mounting
Mounting Dimensions can be found in the SIB datasheet in the Appendix.
The SIB can be mounted using the mounting holes or a DIN tray such as from Phoenix
Contact. If using the mounting holes, standoffs must be used to keep the bottom of the SIB
from shorting with the mounting surface.
Cable Routing
Cable Datasheets can be found in the Appendix.
QuickStart cables come with excellent shielding and make proper grounding easy. This
makes proper cable routing less critical, however proper routing practices should still be
followed.
Route cables to minimize length and minimize exposure to noise sources. The motor power
wires are a major source of noise and the motor feedback wires are susceptible to receiving
noise. This is why it is never a good practice to route the motor power wires close to the
motor feedback wires even if they are shielded. Although both of these cables originate at
the amplifier and terminate at the motor, try to find separate paths that maintain distance
between the two. A rule of thumb for the minimum distance between these wires is 1cm for
every 1m of cable length.
Grounding
Bring all ground wires to a central point ground such as a ground bus, ground plane or a
single ground bolt. Also don't forget to ground the drive chassis! Use the silver screw
marked PE on the case.
Motor Ground – The green wire coming from motor power cable grounds the motor chassis.
If the motor case is already grounded through direct contact with the machine housing,
then leave the green wire disconnected. Grounding the motor at both the green wire and at
the motor case causes a ground loop that has been shown to disrupt the feedback signals.
Choose one or the other.
Load Coupling
A non-rigid coupling must be used between the motor shaft and the load to minimize
mechanical stress due to radial loads, axial loads or misalignment. If you feel that the
radial load on the motor is excessive, you may want to consider connecting the motor to an
idler shaft that is supported by pillow block bearings (or similar). Then the load can be
coupled to the idler shaft without risking damage to the motor bearings.
