Figure 8-3 Sequence with SS1 selection
Functional features of "Safe Stop 1"
● The delay time starts after the function has been selected. If SS1 is deselected again
during this time, the STO function is selected and deselected again straightaway after the
delay time has elapsed or the speed has dropped below the shutdown speed.
● Selection and monitoring of the brake ramp (SBR) or the acceleration (SAM) are
implemented in two channels, however braking along the OFF3 ramp is only through one
channel.
● The "Safe Acceleration Monitor" (SAM) function is selected during braking (see "Safe
Acceleration Monitor").
Note
Activating SS1 may cause the higher-level control (PLC, motion controller), which enters the
speed setpoint, to interrupt the ramp function by triggering OFF2.
The device behaves in this way as a result of a fault reaction triggered by OFF3 activation.
This fault reaction must be avoided using the appropriate parameterization/configuration.
Note
If you use SS1 together with EPOS, then as fault reaction to F07490 (EPOS: enable
withdrawn while traversing) OFF2 is not permitted. The reaction can be configured using
p2100/p2101.
