FOR UNITS EQUIPPED WITH LINEAR ENCODER OPTIONS ONLY:
NOTE: Limit sensors is typically used in conjunction with the encoder ‘ Z ’ marker. If another home location
is desired, the home target can be adjusted by removing the limit flag decal and applying adjustment over-
lay decals in the desired location.
NOTE : Home repeatability is also very dependent on controller input speed and homing algorithms. The
above repeatability does not include possible controller tolerance. Additionally, to achieve the highest re-
peatability the final homing speed must be slow. Slower final speed usually results in higher repeatability.
NOTE : The Z - channel output is only one resolution count wide. Thus the on - time may be very brief. Due
to this some controllers may have difficulty reading the signal. If you are experiencing the positioner not
finding the Z - channel during homing, try reducing final homing speed; also refer to your controller manual
for frequency rates of the Z - channel input.
Grounding / Shielding
All cables are shielded. These shields are to be grounded to a good earth ground. Failure to ground
shields properly may cause electrical noise problems. These noise problems may result in positioning er-
rors and possible run away conditions.
The motor cable has an area of the shield exposed to allow a grounding path from shield to drive ground.
MX80S purchased with ViX drives as part of the configurable part number come equipped with p - clips de-
signed for the small OD of the motor cable to allow the cable shield to be grounded to the ViX ground.
Cabling
The MX80S is provided with high flex cabling which is strain relieved at the connection point on the posi-
tioner. The Encoder cable is terminated with flying leads. The motor cable is terminated with flying leads
which are stripped and tinned and ready for installation into the screw terminals on the ViX drive. For wire
color codes and pin outs see tables in electrical section of manual.
The limit/home cable is provided with either a 15 pin D - sub connector, which is compatible with the ViX
drive, or flying leads. For wire color codes and pin outs see tables in electrical section of manual.
Recommended bend radius for these cables is 50mm. This radius will provide a minimum of 10 million
cycles of the cable. Smaller bend radius will reduce cable life while larger bend radius will increase life.
If the positioner is mounted in a multi - axis configuration special care should be taken in routing and strain
relieving the cables so as to prevent flexing of the cable at the connection to the table and where mounted
stationary to the structure. Provide sufficient service loop that the cable bends a minimum of 25mm from
these end points. It is also recommended to avoid twisting the cable. The cable should be secured in a
position which will orient it in a direction that creates a single plane of operation for the cable.
Cable Management
For multi - axis configurations special attention needs to be taken into account for the moving cables on the
non - base axis.
TIP: For Multi - axis Configurations .
Consider using the top axis for the highest frequency move in the application. The top axis will have the
least amount of weight to move and will reduce the cycles on the cables.
