6 General Parameter Set-up
6.1 Configuration
6.1.1 General Parameter Set-up
See
to configure an operation of
the safety option. The set-up is done via MCT 10 Safe Plug-
in.
Speed monitoring by the safety option
If an external encoder is connected to the safety option
and selected in
42-10 Measured Speed Source
, speed
monitoring is active all the time whether a safety function
is requested or not. However, if a Safe Torque Off is
triggered (either directly, or as a consequence of a Safe
Stop 1) it interrupts the speed monitoring.
Encoder Configuration
To define the type of feedback used by the safety option,
select
[1] Safe option
in
42-10 Measured Speed Source
.
6.1.2 Safety Functions Configuration
The safety functions to be carried out by the safety option
are defined in the MCT 10 Safe Plug-in.
•
Configurations of the safety functions
•
Setting of limit values, braking ramps for the
safety functions, monitoring of motion sequences
NOTICE
Always perform the required commissioning test. The
commissioning test report is automatically generated via
the Safe Plug-in in MCT 10 after downloading the
parameters to the safety option.
Downloading the configuration to safety option.
•
On single-drive systems, via the RS-485/USB
interface on the frequency converter
•
On networked systems, via the RS-485 or fieldbus
interface on the MCT 10 Safe Plug-in. The control
system passes the configuration to the respective
safety option
•
The feasibility of the configuration is checked
when it is downloaded
Further information on configuration and setting
parameters for the safety functions is available in the
online help for the MCT 10 Safe Plug-in and in the
MCT 10
Set-up Software Operating Instructions
.
The safety option is configured with the commissioning
software MCT 10 Set-up Software via a Safe Plug-in. The
Safe Plug-in in the commissioning software is available as
default from version 3.18.
The commissioning software provides the following menu
items for the safety option.
•
General Speed Monitoring
•
Safe Input
•
Safe Stop 1
•
Safely Limited Speed
•
Parameters
•
Status
The menu items are described in detail in the
MCT 10 Set-
up Software Operating Instruction
.
The menu item
Status
shows the following
•
Current signal states of inputs and output
•
Option operating mode
•
Active safety function
The states of the inputs and output cannot be changed via
the commissioning software.
6.1.3 Password Protection
Use a password to protect the system configuration. A
password must be entered only when changing safety
option parameters (writing to option).
Default password is 12345678.
It is advised to change the safety option default password
before downloading the parameter values of a safety
option with factory settings. Only persons knowing the
password can change the safety option parameter values.
