Monitoring without an encoder
The encoderless Safety Integrated functions are configured in the expert list using p9506 =
p9306 = 1 or p9506 = p9306 = 3 or by selecting "without encoder" in the Safety screen form.
For speed monitoring without encoder, the drive is braked along a ramp, which is set using
Safe Brake Ramp (SBR encoderless). The gradient of the brake ramp is defined using a
reference speed (p9581/p9381) and a monitoring time (p9583/p9383). In addition, a delay
time (p9582/p9382) can be set. The brake ramp is effectively monitored once this delay time
expires.
If a Safety Integrated function is activated, e.g. SS1, then the system monitors whether the
actual value of the speed remains below the brake ramp during the complete braking
operation.
For p9506/p9306 = 3, the Safety functions without encoder correspond to the functions with
encoder, and SAM responds just the same as for "monitoring with encoder".

Properties of Safety Integrated parameters
The following applies to Safety Integrated parameters:
● The Safety parameters are kept separate for each monitoring channel.
● During startup, checksum calculations (Cyclic Redundancy Check, CRC) are performed
● Data storage: The parameters will be saved in the non-volatile memory.
● Factory settings for Safety parameters
● The Safety parameterization is password-protected against accidental or unauthorized

on the Safety parameter data and checked. The display parameters are not contained in
the CRC.
A reset of the Safety parameters to the factory setting on a drive-specific basis using
p0970 or p3900 and p0010 = 30 is only possible when the safety functions are not
enabled (p9301 = p9501 = p9601 = p9801 = 0).
A complete reset of all parameters to the factory settings (p0976 = 1 and p0009 = 30 on
the Control Unit) is possible even when the safety functions are enabled (p9301 = p9501
= p9601 = p9801 ≠ 0).
