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

The table below shows the response times
until the response is initiated.
Table 8- 8 Response times for control of the Extended Functions without encoder via terminals (only CU310-2)
Fu n ction
STO
SBC
SS1 (speed controlled/time and acceleration
controlled),
SS1E (time controlled)
SBR or SAM (limit value violation until STO is
active)
SLS speed limit violated
SSM
SDI (limit value violation until
braking is initiated)
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 with a delay.
For t_E, the following applies:
3)
p10017 = 0 t_E = 2 × p0799
p10017 ≠ 0 t_E = p10017 + p0799 + 1 ms
E x tension of t he response t imes for S LS without encoder or SDI without encoder under
c ertain 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 the response times when limit values are
violated and for system errors in order to extend the time value set in parameter p9586
with respect to the standard values (see the table above).
After the time interval set in p9586, the standard response times apply (see table above).
