6 Technical data
Response time until power output stage inactive and maximum
OSSD test pulse duration
The typical response time and the maximum test pulse duration depend on the input
voltage at STOA/STOB:
Characteristic Value
Input voltage (STOA/STOB) 19.2 V 24 V 28.8 V
Typical response time 2 ms 3 ms 4 ms
Max. test pulse duration (OSSD) 0.5 ms 1 ms 1.5 ms
The maximum response time t
STOAB/OFF
is described in section 6.4.2.1 Time response of
the STO activation during operation with a restart on page 67.
6.4.2 Time response
Equal inputs in terms of their functionality
The inputs STOA and STOB are absolutely equal in terms of their functionality, which is
why the switching sequence of STOA/STOB is interchangeable in all of the diagrams.
6.4.2.1 Time response of the STO activation during operation with a
restart
The illustration shows the time response starting with the disconnection of the control
voltage at STOA/B and the sequence that is necessary for restarting the device.
l
The actuation of the holding brake is realised via the basic device and not in a
safety-oriented manner.
l
The illustration shows the coasting of the motor regardless of the
activation/deactivation of the brake
l
The setpoint will not be enabled until the holding brake delay T
F
has elapsed.
l
An error will be issued as the STO inputs are deactivated while the output stage is
active. It is not included in the drawing.
