1) The value does not have an effect on the SMT function, but other safety functions in the FSO module can require
a certain value.
2) The safety data is based on the assumption that this diagnostic measure for the wiring is active (On). If pulsing is
disabled, you must consider other measures to ensure sufficient diagnostic coverage of the wiring failures.
Example value Description
2000 ms Sets the time that is needed to coast the motor to
a standstill from maximum process speed. If this
time is not known, it can be measured with the Drive
Composer pro PC tool when an encoder is used for
motor control (otherwise you have to make sure
that the motor shaft has stopped rotating by other
means, eg, visually).
Acknowledgement is allowed after coast stop in the
STO and SSE functions (when SBC is not used). If
the drive STO is activated or modulation stopped
while a monitoring safety function is indicating
"unsafe", after this time acknowledgement is al-
lowed. For example, if the drive modulation is lost
during SLS deceleration ramp, SLS OK will be indic-
ated after this time has elapsed.
STO function: This parameter sets the time after
which the STO function is completed and the STO
completed indication goes on. Parameter
defines the time after which the acknowledgement
is allowed. Adjust the value according to application
requirements.
When an encoder is used: This parameter is relevant
only if there is an encoder failure and the FSO
module activates the STO function.
None Sets how the mechanical brake is used together
with the STO function.
In the safety functions described in this manual,
this feature is not used and this parameter has value
None.
2)
Sets the diagnostic pulse of digital input X113:4 on
On
or off.
On: The input monitors that it receives test pulses.
Off: The input does not monitor for test pulses.
2)
On Sets the diagnostic pulse of digital input X114:4 on
or off.
On: The input monitors that it receives test pulses.
Off: The input does not monitor for test pulses.
Note: In a non-redundant system, you can use a
one-channel input (for example, DI X113:4). In this
case, this parameter has no effect.
