Control Of Extended Functions Without Encoder Via Terminals (Only Cu310-2) - Siemens SINAMICS S120 Function Manual

8.4.8

Control of Extended Functions without encoder via terminals (only CU310-2)

The table below shows the response times
until the response is initiated.
Extension of the response times for SLS without encoder or SDI without encoder under
certain circumstances
If the safety functions SLS without encoder or SDI without encoder are already selected
when the gating pulses for the Power Module are enabled, then during the starting phase, it
is absolutely imperative that you take into account that the response times – when limit
values are violated and for system errors – are extended by the time value set in parameter
p9586
After the time interval set in p9586, the standard response times apply (see table above).

The specified response times are valid for Extended Functions with and without selection!
1)
Start phase: This describes the behavior after switching on (ON command with previously deleted pulses).
2)
Standard: This behavior applies when the pulses have already been enabled.
There is a different behavior because, with the aid of p9586, the encoderless actual value acquisition after pulse enable
can only be activated after a delay.
For t_E, the following applies:

p10017 = 0 t_E = 2 · p0799
p10017 ≠ 0 t_E = p10017 + p0799 + 1 ms
