Instance Attribute “Warning”
The data type of this attribute is BOOL. The Attribute Identifier of this attribute is 11
d
. This attribute
is used to signal that one or several warnings have appeared in the drive. The value of the attribute
is 1 if a warning has appeared and has not been acknowledged. Otherwise, the attribute has the val-
ue 0 indicating that no warnings are present.
Instance Attribute “FaultRst”
The data type of this attribute is BOOL. The Attribute Identifier of this attribute is 12
d
. This attribute
is used to reset faults and warnings in the drive. The attribute is read-write. When the value of the
attribute is changed from 0 to 1 (rising-edge) then this will reset faults in the drive. If the value is
static 0 then no action is started.
Instance Attribute “FaultCode”
The data type of this attribute is UINT (16-bit). The Attribute Identifier of this attribute is 13
d
. This
attribute is used to read the kind of fault which has caused the device to transition into the “Faulted”
state. In the case of multiple faults occurring simultaneously, only one code is reported. If the de-
vice is not in the Faulted state, the FaultCode attribute indicates the fault which caused the last
transition to the Faulted state.
Instance Attribute “CtrlFromNet”
The data type of this attribute is BOOL. The Attribute Identifier of this attribute is 15
d
. The attribute
is read-only. It indicates whether run/stop control is assigned to the local interface or to this net-
work interface. When the value of the attribute is 0, control is local. When the value of the attribute
is 1, run/stop control is assigned to the network interface.
Instance Service “Reset”
The Control Supervisor Object has a instance service named “Reset” which has the Service Code
05
h
. The service resets the drive to the start-up state by setting the Control Supervisor state ma-
chine to the Startup state. Parameters are not changed.
If an error is detected, an error response is returned. Otherwise a successful Reset response is re-
turned.
Control Supervisor State Machine
The Control Supervisor Object defines a state machine for governing the behavior of devices. The
figure below describes the states and transitions of the state machine.
