Activation
For activation of the Safety Integrated Extended Functions "with encoder" and "without
encoder", set the parameters p9306 and p9506 (factory setting = 0). You can also make this
setting by selecting "with encoder" or "without encoder" on the Safety-Integrated Startdrive
screen. To do this, in Startdrive, in the secondary navigation of the drive axis, select the
"Drive functions > Safety Integrated > Function selection" menu item
● Operation with encoder
p9506 = 0
or
p9506 = 2
● Operation without encoder
p9506 = 1
or
p9506 = 3
Monitoring with an encoder
The Safety Integrated Functions with encoder are configured with p9506 = 0 (factory setting)
or p9506 = 2 in the expert list or by selecting "with encoder" in the Safety screen.
● If p9506 = 0:
Braking is monitored with the "Safe Acceleration Monitor" function.
● If p9506 = 2:
Here, also for SS1, the monitoring function "Safe Brake Ramp" is active.
More detailed information on actual value acquisition with encoder can be found in Section
"Notes regarding safe actual value sensing using an encoder system (Page 155)".
Monitoring without an encoder
The Safety Integrated Functions without encoder are configured in the expert list using
p9506 = 1 or p9506 = 3 or by selecting "without encoder" in the Safety screen form.
● For p9506 = 1, the following applies:
Here, also for SS1, the monitoring function "Safe Brake Ramp" is active.
● For p9506 = 3, the following applies:
Braking is monitored with the "Safe Acceleration Monitor" function. The behavior
corresponds to "monitoring with encoder".
