MECHATROLINK Communications Control
Section 6-3
Restrictions in Establishing a Connection According to Servo Drive Status
Functionality for axis operations after establishing a connection depends on
the unit version of the PCU as described below if the following conditions exist
when a connection is established for an axis (Servo Drive) registered in the
scan list.
• Disconnection
• Control power supply interruption
• An alarm that cannot be reset (i.e., when the power must be cycled)
■
PCUs with Unit Version 1.2 or Earlier
An MLK initialization error (unit error code 0020 hex) will occur in these situa-
tions, and operation for MECHATROLINK communications will stop for all
axes. To start MECHATROLINK communications normally, any errors must be
cleared for all axes registered in the scan list before establishing a connection.
■
PCUs with Unit Version 1.3 or Later
Axis operation is possible for axes that are registered in the scan list and for
which MECHATROLINK communications was started (i.e., axes for which
Axis Communications Status Flags are ON), regardless of whether an alarm
is present in the Servo Drive or whether the connected axes match the scan
list. If MECHATROLINK communications cannot be started for all axes regis-
tered in the scan list, an MLK initialization error (unit error code 0020 hex) will
occur to provide notification of the inconsistency between the registered axes
and the axes that are communicating.
The following example shows the restrictions in operations according to axis
status when connections are established.
