Safety-related characteristic data for operation with non-safety-related
rotary encoder with diagnostics via the drive controller
The detection of encoder errors (diagnostics for the sensor subsystem via the evaluation
device) can be supplemented with a drive controller.
Permitted encoder types and output signals
Permitted encoder types:
} Rotary non-safety-related encoders
} Linear non-safety-related encoders
Permitted output signals:
} Square output signals TTL, single ended
} Square output signals TTL, differential
} Square output signals HTL, single ended
} Square output signals HTL, differential
} Sin/Cos output signals 1Vss, reference voltage
} Sin/Cos output signals 1Vss, differential
Requirements of the drive controller
} Parameters for the control loops and motor control must be set in such a way as to
guarantee stabile operation.
Drag error detection (see below) must be capable of operating in accordance with the
requirements of the safety function.
} The motor must be operated with a current impressing control procedure, based on the
rotor position (field-oriented control). If the analogue track signals are idle, field-oriented
control will brake and/or stop the rotor.
} The drive controller must be in position control operating mode.
