3.5.2 Operation mode selection
Short overview of "Safety functions Operation mode selection" parameter group:
3.5.2.1 Operation mode selector (OMS)
Parameter Information Lenze setting
Value Unit
C15200 OMS: Stop function STO
C15201
OMS: Motion function Free traversing
Operation Mode Selector / OMS
Description This function serves to switch between normal operation and "special operation" of the drive.
The special operation enables the overriding of a standard stop (STO and SS1 ) by release
through an enable switch. Enable switch (ES)
( 32)
Conditions • 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
).
• The 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.
Function
Basic status of normal operation
If special operation is requested, the stop function parameterised for special operation
(STO
or SS1) is activated.
A release through the enable switch enables the motion function ( free traversing)
parameterised for the special operation.
Parameter C15200 OMS: Stop function
C15201
OMS: Motion function
• The "Free traversing" setting must be suitable for the application!
Requesting the
special operation
How to request the special operation:
• "ON state" at a safe input to which the "operation mode selector" function has been assigned
by parameter setting. Safe inputs
( 42)
• Only if no safe input is used, the function can be activated via the safety bus by sending a data
telegram with a corresponding content to the controller.
Deactivating the
special operation
A change-over from special operation to normal operation is only possible when the drive is at
standstill (stop function STO
or SS1 active).
• For a restart, the restart must be acknowledged (AIS) via terminal or safety bus.
• The automatic restart is not permitted. If the "Automatic restart" is parameterised, this must
be prevented by special measures, e.g. programming in the master control.
Error behaviour • The emergency stop function can be triggered in both operating modes.
