Function
 Basic status of normal operation
 If special operation is requested, the stop function (
STO , SS1 or SS2 ) parameterised for
special operation is started.
 Via enable through the enable switch, the motion function ( SLS or free traversing)
parameterised for special operation is possible. Furthermore the SLI monitoring function
(safely limited increment) can be switched on for the motion function parameterised.
Parameter  C15200 OMS: Stop function
 C15201 OMS: Motion function
• The "Free traversing" setting must be suitable for the application!
C15202 OMS: Function at LOW level
 C15203 Safely limited increment
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 ( 34)
• 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.
 If the OMS bit is received via the safety bus, the value 0 (normal operation) is adopted in the case
of passivation. In special applications (e.g. safety door requests OMS, i.e. open safety door =
special operation), this must not lead to a dangerous state through an automatic restart!
Deactivating
special operation
A change-over from special operation to normal operation is only possible when the drive is at
standstill (stop function STO , SS1 or SS2 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 monitoring functions SMS and SLS can be activated in both operating modes and trigger
the parameterised stop function in the event of a error.
• If the SLI monitoring function is active, exceeding the position window activates the
parameterised stop function for special operation.
• The emergency stop function can be triggered in both operating modes.
