Chapter 3 Configuring the Drive in a Logix System
Along with the configuration of the Safe Speed Monitor (SSM), the password
for the module is stored in the configuration script in the controller. The
password is used as part of the connection process to allow the configuration
that is stored in the controller to be downloaded to the module. This password
must be entered into the profile for the 20-750-S1 module (S1) in the Module
Properties dialog box of the drive, in RSLogix 5000 / Studio 5000 application.
This password value is entered in Parameter 13 of the 20-750-S1 module (S1)
on controller download to the module. Record the parameter value for future
use when interacting with the module. Enter the password into
Parameter 1 for the 20-750-S1 module (S1) to allow either locking via
Parameter 5 or by changing the password via Parameter 13 and 17.
The following manual steps take an existing configured SSM out of Run mode
to allow the controller to download the configuration to the new SSM. For
example, during replacement of the drive and reuse of the existing module.
1. Inhibit the drive connection—or disconnect the communication card
through which the controller is trying to configure the 20-750-S1
module by using ADC.
2. Set SSM Parameter 1 [Password] to the current password of the
module.
3. Set the SSM Parameter 5 [Lock State] to ‘0’ (Unlock).
4. Set the SSM Parameter 6 [Operating Mode] to ‘0’ (Program).
5. If the SSM password is not ‘0’, change the password of the Module to ‘0’.
6. Set the SSM Parameter 1 [Password] to the current password of the
module.
IMPORTANT Firmware Supervisor cannot be used to update the 20-750-S1 module
firmware, due to unique upgrade components within its safety core. The
firmware can be manually upgraded using ControlFLASH, a 1203-USB Serial
Converter, and the appropriate upgrade file.
IMPORTANT Before you save the configuration to the controller, do not set the SSM
parameters in the Add-on Profile configuration:
• Parameter 5 [Lock State] to ‘1’ (Lock)
• Parameter 6 [Operating Mode] to ‘1’ (Run)
By setting these parameters, you lock the Module, stop writing the higher
numbered parameters, and cause the ADC download to fail. These two
parameters must be changed manually after performing an upload or after
the ADC download.
IMPORTANT Perform these manual steps when the Ethernet cable is disconnected from
the drive.The controller, while attempting to configure the S1 Module locks
out writes from other sources, such as the HIM.
