Note that after setting DeviceLogix Parameter 53 to ‘0’ (Enable Logic), the value
will be changed by the drive to ‘6’ (Logic Enabled) to indicate operation status.
Special Considerations When Using a 20-750-S1 Safe Speed Monitor Module
There are special considerations when using ADC with the 20-750-S1 Safe Speed
Monitor Module. Safety requires manual intervention by the user before the
drive can become operational. Although a manual ‘step’ is required, ADC can still
be used.
In addition to the configuration of the Safe Speed Monitor Module, the
password for the Module is stored in the configuration script in the controller
and used as part of the connection process to allow the configuration stored in
the controller to be downloaded to the Module. This password will need to be
entered into the profile for the Safe Speed Monitor Module in the drive’s Module
Properties dialog box in RSLogix 5000 software. This password value is the value
entered in parameter 13 of the Safe Speed Monitor Module on controller
download to the Module, which is required by procedure to be recorded by the
user for future use when interacting with the Module. When using this password
in the future, it would be entered into parameter 1 for the Safe Speed Monitor
Module to allow either locking via parameter 5 or password changing via
parameters 13 and 17.
The following manual steps may be needed to take an existing configured Safe
Speed Monitor Module (for example, replacing the drive and reusing the existing
Module) out of Run mode to allow the controller to download the configuration
to the Safe Speed Monitor Module. (Note that these manual steps may need to be
performed with the Ethernet cable disconnected from the drive as the controller’s
attempts to configure the Safe Speed Monitor Module will include locking out
writes from other sources, such as the HIM).
IMPORTANT Do not set DeviceLogix parameter 53 - [DLX Operation] to ‘0’ (Enable Logic) in
the Add-on Profile configuration before saving the configuration to the
controller. This setting would lock the module and prevent writing the higher
numbered parameters, thus causing the ADC download to fail.
IMPORTANT Firmware Supervisor cannot be used to update the 20-750-S1 Safe Speed
Monitor Module firmware. This is due to unique upgrade components with its
safety core. It can be manually upgraded using ControlFLASH, a 1203-USB
Serial Converter, and the appropriate upgrade file.
IMPORTANT Do not set Safe Speed Monitor Module parameter 5 [Lock
State] to ‘1’ (Lock); or parameter 6 [Operating Mode] to ‘1’
(Run) in the Add-on Profile configuration before saving the
configuration to the controller. Setting these parameters would
lock the Module and prevent writing the higher numbered
parameters, thus causing the ADC download to fail. These two
parameters need to be changed manually after performing an
upload or after the ADC download.
