Kinetix 2000 Connector Data 53
SERCOS Connections
Two fiber-optic connectors (transmit and receive) are provided on the
integrated axis module (IAM) and axis module (AM).
SERCOS Communications Specifications
Node addresses for axes on the same power rail are assigned by incrementing
from left to right (starting with the IAM address). One SERCOS node address
goes unused for each double wide AM on the power rail.
Contactor Enable Relay
Contactor enable is a relay-driven contact used in the safety control string to
protect the drive electronics during certain fault conditions. It is capable of
handling 120V ac or 24V dc at 1 A or less. Contactor enable is a function of
the converter and is not available in the axis modules.
An active state indicates the IAM is:
• Control power is applied.
• No axis shutdown fault is detected.
• All power rail slots are occupied with a valid module.
Attribute Value
Data Rates AutoDetect, 4 Mbps, and 8 Mbps
Cycle Times 0.5 ms, 1.0 ms, and 2.0 ms
Transmit Rates Low, and High
Node Addresses 01...99
(1)
(1) Node address assignments begin with the integrated axis module (IAM).
ATTENTION
Wiring the contactor enable relay is required. To avoid personal injury
or damage to the drive, wire the contactor enable relay into your
safety control string so that:
• three-phase power is removed from the drive in the event of
shutdown fault conditions.
• drive operation is prevented when the power rail is not fully
populated.
• control power is applied to the drive prior to three-phase power.
Refer to Single-Phase Power Input (without LIM) to IAM Wiring
Example on page 173 for a wiring example.
The recommended power up sequence is to apply Logix power, and
then close the CE relay to apply main power to the drive electronics.
