NOTICE
If the selected encoder resolution is below 150 PPR for
HTL/TTL encoder, set a feedback filter value in
42-15 Feedback Filter
. The system then calculates an
allowed value. This is also the case when using a
proximity switch feedback where the encoder resolution
is below 600 PPR.
NOTICE
Depending on the system, a movement can imply
different directions for the motor encoder.
NOTICE
Depending on the application, the motor encoder may
be connected via a gearbox.
5.2.5 Commissioning Test
The MCT 10 Safe Plug-in creates a commissioning report
based on the commissioning test result. It generates the
frequency converter safety signature. This function
provides a final report when the safety option has been
configured. This report is considered as a help tool for
safety commissioning and validates that all the safety
functions are operational. The commissioning report can
either be printed or converted into a PDF file.
The test objective is to verify proper implementation
(forced dormant error detection measures) and to examine
the response of specific monitoring functions to the
explicit input of values outside tolerance limits.
WARNING
After hardware and/or software components have been
modified or replaced, all protective equipment must be
closed before system start-up and activation of the
frequency converter. Personnel must keep out of the
danger zone. It is mandatory to carry out a partial or
complete commissioning test after having made certain
changes or replacements. Before allowing anybody to re-
enter the danger zone, test the steady control response
by briefly moving the frequency converters in forward
and reverse direction (
±
).
EN IEC 61508, EN IEC 62061 and EN ISO 13849 require that
the final assembler of the machine validates the operation
of the safety function with a commissioning test. The
commissioning tests for the standard safety functions Safe
Stop of the frequency converter are described in the
frequency converter manuals. The tests for the optional
safety functions are described in the commissioning report
generated by the MCT 10 Safe Plug-in. The commissioning
test must be performed
•
at initial start-up of the safety function
•
after any changes related to the safety function
(wiring, components, settings, etc.)
•
after any maintenance work related to the safety
function.
5.3 Operation
WARNING
UNINTENDED BEHAVIOUR
Numerous stored data or settings govern the behaviour
of the frequency converter system. Unsuitable settings or
data may trigger unexpected movements or responses to
signals and disable monitoring functions.
•
Do NOT operate the frequency converter system
with unknown settings or data
•
Verify that the stored data and settings are
correct
•
When commissioning, carefully run tests for all
operating states and potential error situations
•
Verify the functions after replacing the product
and also after changing the settings or data
•
Only start the system if there are no persons or
obstructions in the hazardous area
Failure to follow these instructions can result in death,
serious injury or equipment damage.
Prerequisites for normal operation are
•
commissioning is complete
•
the safety option contains the configuration data
•
the safety functions have been tested
•
LED1, LED2 and LED4 are lit
During operation
•
any pulse edge change at the safety option safe
input is monitored
•
the safety functions are performed in accordance
with the configuration
