Kinetix 6000M System Connector Data Chapter 4
Sercos Fiber-optic Connectors
The sercos fiber-optic ring is connected by using
the sercos receive (RX) and transmit (TX)
connectors.
Table 12 - Sercos Specifications
Enable Input
One digital input is supplied to enable all connected IDM units.
The enable status is transmitted to all of the IDM units.
Table 13 - Enable Input Specifications
ATTENTION: To avoid damage to the sercos RX and TX connectors use only
finger-tight torque when attaching the fiber-optic cables. Do not use a wrench
or any other mechanical assistance. For more information, refer to Fiber-optic
Cable Installation and Handling Instructions, publication 2090-IN010
.
Attribute Value
Data rates 8 Mbps (fixed)
Light intensity Adjustable, low or high power, selectable via the keypad/LCD display (see page 68
).
Cyclic update period 500 μs, minimum
Node addresses Assigned on each IDM unit, see page 70
. The IPIM module does not have a sercos address
since it is not a sercos device.
