Commissioning
6) If the delay time value programmed is greater than 0 s (SS1-t safety function), it is necessary
to configure the time for the deceleration ramp that CFW900 will execute during a demand
of the SS1-t safety function. In this case, the HMI displays a screen asking if the user wants
to use the same value for the delay time and the deceleration time.
7) To use a different value for the deceleration ramp, select "NO" and define the desired value
on the next screen. Press the Enter key to confirm.
NOTE!
If the SS1-t ramp deceleration time is set to a time value greater than the
programmed SS1 delay time ( S4.2 ), the STO state will be reached before the
complete stop of the motor.
NOTE!
If the programming is aborted during steps 6 or 7, CFW900 will use for the
deceleration time the same value programmed for the SS1-t delay time.
8) After programming and confirming the delay time, the user must return the DIP switches
S2 to the "OFF" position. At this point, CFW900 exits the programming state and returns
to the STO state.
