382 Configuration
1. SLS request is activated (SLSx.11 SLS1 input A = DI X113:2 & X114:2). SLS time
delay monitoring is started (SLSx.04 SLS time delay = 2000 ms). Deceleration to
SLS limit speed is started (23.13 Deceleration time 1).
2. Modulation is lost. Motor starts to coast to a stop. SLS time monitoring limit is
disabled when modulation is lost (SLSx.04 SLS time delay = 2000 ms). Time to
zero speed with STO and modoff starts to run (STO.14 Time to zero speed with
STO and modoff = 2500 ms).
3. Modulation of the drive does not return. After STO.14 has elapsed, SLS indication
goes on (SLSx.15 SLS1 output A = DO X114:7).
The time monitoring of the SLS function is disabled when modulation of the drive is
lost during SLS deceleration ramp. When the drive stops modulation, FSO disables
the time monitoring of the SLS function and starts to wait that the motor will coast to
zero speed (STO.14 Time to zero speed with STO and modoff). When STO.14 has
elapsed, SLS indication goes on. STO.14 delay should be parametrized so that when
this time has elapsed, the motor speed is 0.
