Note!
During online communication via bus system, multiple users can access the
very same drive at the same time and edit the safe parameter set. After the
safe parameter set has been transmitted, please check if the checksums (CRC)
of the parameter set, memory module, and safety module in the "Safe
transfer" dialog are consistent.
The consistency of the safe parameters must be ensured by organisational
measures because there are no technical means to avoid multiple users
accessing parameter sets at the same time.
1.6.1 Parameter setting
Safety−relevant parameters can exclusively be transmitted to the safety module by safe
parameter setting. The parameter set is saved in the memory module and safety module
with a definite module ID which must comply with the effective safety address in the
safety module.
A safe parameter setting requires the service status. The service status means the
following:
ƒ The standard stop is active and the drive is safely switched to torqueless operation
(STO).
ƒ The communication via the safety bus is active but passivated.
About the service status:
ƒ It can be activated by the Lenze »Engineer« PC software.
ƒ It can be quit by reinitialising the module, i.e. the communication via the safety
module is interrupted.
)
Note!
The service status also occurs if the parameter set in the memory module does
not comply with the parameter set in the safety module during initialisation.
Observe the information on compatibility of the SM301 firmware versions (
¶ 19).
1.6.1.1 Parameter setting with the Lenze »Engineer« PC software
Safe parameter setting is supported by the Lenze PC software »Engineer« as of version 1.4.
The parameter setting is described in the Software Manual for the SM301 safety module.
Moreover, the software provides a comprehensive Online Help.
Password
For storing a safe parameter set, a password is required. The standard password is: "Lenze
SM301". The password can be changed and must have at least six characters.
Use "general reset" to delete the safe parameter set in the memory module and the safety
module. The safety module must be reparameterised.
The password is reset to the standard "Lenze SM301".
