3. Functional safety
3.1 Safety Funcions
According to DIN EN 61800-5-2, the following safety functions can be achieved with the encoder:
• SS1: Safe Stop 1 Monitoring of the braking ramp and STO after standstill
• SS2: Safe Stop 2 Monitoring of the braking ramp and SOS after standstill
• SOS: Safe Operating Stop Monitoring of the standstill of the energized and
controlled motor
• SLS: Safe Limited Speed Monitoring of a speed limit value.
• SLI: Safe Limited Increment The respect of a specific step value during motion
of Position
is monitored.
• SDI: Safe Direction Monitoring of the unintended direction of motion of the motor.
• SSM: Safe Speed Monitoring A safe output signal is generated when the motor speed is
lower than a specified value.
3.2. Safety Concept
Incremental Encoder Funcion
In order to achieve safe incremental information
with the encoder, the controller must monitor the
validity of the analogue, 90° phase-shifted
sine/cosine signals with the help of the function
sin 2 (x) + cos 2 (x) = 1
The risk of mechanical faults (as might occur, for
example, if the rigid torque stop with torque pin
were to break or the encoder to fall off the motor
shaft) is eliminated as a result of the mechanical
over-dimensioning of the components of our
safety encoders.
The encoder is safe only when used in conjunction
with a safe controller that can monitor the
functions mentioned.
The encoder does not prevent from switching
the plant on again after a malfunction; if this
function is necessary, it is to be ensured by the
control.
