Stable operation with active extended functions without encoder
The following requirements must be fulfilled to avoid error messages from the safe actual
value acquisition without encoder:
● Make sure that the motor and the power unit are adequately dimensioned for this
application.
● Make sure that the ratio between the rated power unit current (r0207[0]) and rated motor
current (p0305) is less than 5 for the motor and the power unit.
● Before commissioning the safety functions, identify the motor data at standstill and
perform a rotating measurement.
● For the basic commissioning (i.e. before the safety commissioning), set the closed-loop
control optimally. The following effects should be avoided:
– Speed overshoots
– Current peaks or discontinuous actual current value characteristic
– Voltage peaks or discontinuous actual voltage value characteristic
– The lowest possible amount of noise in the current and voltage
STO/SBC (Extended Functions)
The "Safe Torque Off" (STO) function prevents energy from being supplied to the motor
which can generate a torque.
The "Safe Brake Control" (SBC) function supplies a safe output signal for controlling a
holding brake.
Configuring safety functions
The Safety Integrated Extended Functions are only partly configured in the "STO/SBC"
screen form. Most of the configuration is performed in other screen forms. A procedure is
described in the following if you want to configure the two safety functions.
1. Call the "STO/SBC" safety functions.
A screen form with the same name opens.
