Parking note

Note
When a drive object for which the "Safely Limited Speed" function with encoder is enabled is
switched to "Park" mode, the Safety Integrated software responds by selecting STO without
generating a separate message. This internal STO selection is displayed in parameter
r9772.19.

Safely-Limited Speed with encoder

Functional features of "Safely Limited Speed" with encoder
To ensure that the drive reaches the reduced speed below the new speed limit value once
the delay time has elapsed, it must be braked accordingly within the delay time by means of
the higher-level motion control/setpoint channel. The previous SLS limit value is still active
during the delay time.
● A selected speed limit is activated once SLS has been selected and after the delay time
● However, if the ACTUAL speed is higher than the new speed limit value after the delay
● The stop responses are parameterized using p9363/p9563.
● The delay time is not active when switching over to a higher speed limit value.
● 4 parameterizable speed limit values p9331[0...3] and p9531[0...3]
A speed setpoint limit can be set as percentage in p9533. This value is used to calculate a
speed setpoint limit r9733, depending on the selected speed limit p9531[x].

(p9351/p9551) has elapsed. When switching over to a lower speed limit value, the speed
must be braked to below the new maximum limit value within this delay time.
time has expired, an appropriate signal is generated with the parameterized stop
response.
