3.9.3 Operation mode selection
Short overview of "Safety functions  Operation mode selection" parameter group:
3.9.3.1 Operation mode selector (OMS)
Parameter Info Lenze setting
Value Unit
C15200 OMS: Stop function STO
C15201 OMS: Motion function SLS1
C15202 OMS: Function at LOW level * Normal operation
C15203 Safely limited increment ** 1 Incr.
* From SM301 V1.3 ** From SM301 V1.4
Operation Mode Selector / OMS
Description
This function serves to switch between normal operation and "special operation" of the drive.

• Special operation enables the overriding of a standard stop ( STO , SS1 and SS2 ) by release
through the enable switch.  Enable switch (ES) ( 56)
• From SM301 V1.4: The monitoring function of the safely limited increment is active as soon
as a value > 0 has been entered in C15203 . The setting "0" deactivates the SLI monitoring
function.
• The monitoring function parameterised is automatically activated with the transition to
special operation. A motion function other than "traverse freely" at the same time is
monitoring function in special operation.

OMS: Function at LOW level
If the operation mode selector is implemented via a safe input, the operating mode for the LOW
level is to be selected with care (from SM301 V1.3) .
According to the closed-circuit principle, no additional danger must be caused by normal or
special operation in the corresponding application.
For detailed information, please see the manual for the safety module.
Preconditions • A safe input must be parameterised and interconnected as an operation mode selector. You
can only connect and parameterise one operation mode selector. The OMS bit of the safety
bus must be deactivated ( C15113 ). When a safe input is used, the LOW level function must
be set depending on the application (from SM301 V1.3) .
• Special operation can also be selected via the safety bus with the OMS bit unless a safety
input is set as an operation mode selector.
• The plausibility check rejects ambiguous settings until you have parameterised them
correctly.
