Ⅻ.Common faults and trouble shooting
一．
failure and failure elimination of swing controller:
1) MICRO SLAVE KO
CAN Bus code = 246
-
Reason: Use in stepping moter.When the stepping moter direction which is tested by the
Lord
microprocessor doesn’t match with the direction which is tested by microprocessor
,
fault alarm.
Turning error of
the
Lord microprocessor doesn’t match with the direction
which is tested by microprocessor.
besides
，
inspection transfer of
the
Lord microprocessor without limitation
and the microprocessor has.
- Handle:
Should change the controller.
2) MICRO SLAVE #4
CAN Bus code = 221
- Reason:
One of the meet the following conditions
accurred fault:
(Should be limited to open cycle system) Direction of turning of stator
voltage which is tested by
microprocessor is contrary to the speed signal of
stepping motor ,
fault alarm.
(Should be limited to closed-loop system) Direction of turning of stator
voltage which is tested by
microprocessor is contrary to the setting
direction,
fault alarm.
- Handle:
Should change the controller.
3) MICRO SLAVE
CAN Bus code = 250
-
Reason
:
when the message bus between
microprocessor and
the
Lord
microprocessor is locked to numerical value
0xFF, (microprocessor can’t be
upgraded to the state of trunk configuration)
，
failure warming will be happen
.
- Handle:
Should change the controller.
4) MICRO SLAVE #8
CAN Bus code = 212
-
Cause
:
The
Lord microprocessor which is calculated by encoder does not match
with microprocessor,
fault alarm.
- Handle:
Should change the controller.
5) INPUT ERROR #1
CAN Bus code = 99
-
Cause
:
Before the security contacts closing
，
voltage of CNA#4 is higher than12V .(NK1:
low potential of safety junction (see 7.6)
，
fault alarm.
- Handle:
When security contact disconnect
，
CNA#4 voltage approachs 0V
，
This
quantity of battery positive terminal or negative terminal is
independent(see 7.6)
。
The fact is (Security contact is connected with battery positive
terminal), When security contact disconnect, CNA#4 through load to
connect with battery negative terminal. Only NK1 connection with the
device errors occur, voltage will be higher than 12 V.
6) SERIAL ERR #1
CAN Bus code = 6
- Cause:
Communication between
microprocessor and
the
Lord microprocessor
through local serial interface
。
When the Lord microprocessor can't through the serial interface to
send information from microprocessor, fault alarm
。
-
Handle: Should change the controller.
7) SLAVE COM. ERROR
CAN Bus code = 227
- Cause:
Communication between
microprocessor and
the
Lord microprocessor
through local serial interface.
When the Lord microprocessor can't through the serial interface to
send information from microprocessor, fault alarm
。
