Block header
Input parameters
• SSNR: Safety subroutine number
Permitted value range: 1 ... 200
Format: Byte constants KB001 ... KB200
(see sections in Chapter 5 entitled “Administration data blocks
DB015, DB016 and DB017” and “Input parameter SSNR”).
• STFG: Static enable
STFG = 0: Function disabled
STFG = 1: Function enabled
The two-hand control can only be enabled (
FG = 1) if STFG is
high. The STFG signal is the result when all the signals that
must be present to operate the press are linked (e.g. FG from
the E-STOP, FG from the operating mode selector switch etc.)
• MEin: Machine “On”
A 1/0-pulse edge on the
MEin signal activates a lock (single-
stroke protection), which will only be lifted when the start
position is achieved (both buttons T1 and T2 released).
MEin = e.g. “Safety valve on” flag: Activation of lock required
MEin = RLO-0 (M 110.00): Activation of lock not required.
