ERRORS 6000-6999
6000
'Feedback alarm'
DETECTION
During execution.
CAUSE
Feedback error on analog axes. It is enabled by means of machine parameter
FBACKAL.
DIFFERENTIAL TTL:
• One or more cables broken (A, B signals or their inverted signals).
• Feedback input disconnected at the counter.
DIFFERENTIAL SINUSOIDAL:
• One or more cables broken (A, B signals or their inverted signals).
• Feedback input disconnected at the counter.
• Input signal amplitude above 1.45 Vpp (approx.)
• Input signal amplitude under 0.4 Vpp (approx.)
• Too much phase shift between A and B signals (in quadrature, in theory)
For non-differential signals, the feedback alarm (FBACKAL) must be disabled
because it cannot be determined for sure.
SOLUTION
Contact our technical service department.
6001
'Tendency test alarm activated'
DETECTION
When an axis runs away and the tendency test monitoring is activated.
CAUSE
Axis runaway. Positive feedback on the axis for a longer period of time than what is
set by parameter ESTDELAY.
SOLUTION
Check the sign of the velocity command and of the feedback. Set parameters
ESTDELAY, command sign AXISCHG and feedback LOOPCHG.
6002
'The PLC program is not running'
DETECTION
Continuous monitoring of PLC status.
CAUSE
The PLC program is not running.
• Installation of a new software version.
• The PLC has been stopped and has not been resumed.
SOLUTION
Set the PLC program running. Compile the PLC program if necessary.
6003
'External emergency activated'
DETECTION
Continuous monitoring from each interpolation cycle.
CAUSE
The PLC mark _EMERGEN has been set to zero.
SOLUTION
Check the logic of the _EMERGEN signal in the PLC program.
6004
'Error when initializing the BUS CAN'
CAUSE
The drive reports an error.
SOLUTION
Analyze error codes. Refer to the drive manual.
6005
'Error when selecting the work frequency of the BUS CAN'
DETECTION
During system startup.
CAUSE
One or several nodes are not tuned in to the frequency set by parameter.
SOLUTION
Check the following:
• The CAN cable distance matches the frequency parameter.
• See if all the modules are recognized in diagnosis mode.
Contact our technical service department.
