9.2 Parameters for SINAMICS S120
p9821 BI: SI Safe Brake Adapter signal source (Motor Module)
Sets the signal source for the Safe Brake Adapter (SBA).
This therefore defines via which digital input the Safe Brake Adapter checkback
signal (SBA_DIAG) is read in.
p9621/p9821 = 0:
There is no Safe Brake Control (SBC) with Safe Brake Adapter (SBA) available.
p9621/p9821 = r0722.x (x = 0, 1 ... 7)
Safe Brake Adapter and booksize device (no Communication Interface Module
(CIM)).
p9621/p9821 = r9872.3
Safe Brake Adapter and chassis device (CIM).

For a crosswise data comparison between p9621 and p9821, no difference is tol‐
erated. The following must apply when using the "Safe Brake Adapter" function:
p9601 = p9801 <> 0 and p9602 = p9802 = 1
Unit: Default value:
- 0
p9822[0...1] SI SBA relay wait times (Motor Module)
Sets the wait times for switching on and switching off the Safe Brake Adapter relay.
The relay-specific minimum wait times to evaluate the feedback signal contacts
must be set. For a relay, these differ when switching on and switching off.
[0] = wait time, switching on
[1] = wait time, switching off
See also: p9622
The set time is internally rounded off to an integer multiple of the monitoring clock
cycle (r9780/r9880).
For index 0:
Wait time switch on = drop-out time + bounce time NO contact + effect of the
freewheeling diode in the Safe Brake Adapter
For index 1:
Wait time switch off = response time + bounce time NC contact + effect of the
freewheeling diode in the Safe Brake Adapter
Unit: Default value:
μs [0] 100000.00
[1] 65000.00
