5.5.2.2 Beta
The device's Beta angle in relation to the trigger position is defined under the Beta parame-
ter.
5.5.2.3 Gamma
The device's Gamma angle in relation to the trigger position is defined under the Gamma
parameter.
5.6 Increment configuration
The Increment configuration tab contains the parameters for converting the signals for di-
stances and speeds.
The signals are either generated by the configuration software (SOPAS) or CAN interface, or
via an incremental encoder on the digital input. Incremental encoders refer to sensors for
capturing positional changes (linear) or angle changes (rotating) that can capture the di-
stance and direction or angle change and direction of rotation. They are also known as ro-
tary encoders, incremental rotary encoders, and rotary pulse encoders.
5.6.1 Increment
The Increment group contains parameters for converting signals for distances and speeds.
The signals are either generated by the configuration software (SOPAS) or via the CAN inter-
faces or are generated via an incremental encoder on the digital input. Incremental enco-
ders refer to sensors for capturing positional changes (linear) or angle changes (rotating)
that can capture the distance and direction or angle change and direction or rotation. They
are also known as relative encoders.
5.6.1.1 Increment source
The Increment source parameter is used to select the source of the incremental signals:
• F
IXED SPEED: You can use the Fixed speed parameter to enter a constant value for the feed
speed of the belt.
• S
ENSOR 1: The incremental signals are expected from a rotary encoder connected at digi-
tal input 1. You configure the digital input using the parameters for the Sensor / Result 1
group. The maximum input frequency at the input is 300 Hz.
• S
ENSOR 2: The incremental signals are expected from a rotary encoder connected at digi-
tal input 2. You configure the digital input using the parameters for the Sensor / Result 2
group. The maximum input frequency at the input is 300 Hz.
• CAN: The incremental signals are expected via the CAN interface.
• SOPAS C
OMMAND: Corresponding commands are expected as incremental signals. The
commands can be generated by an external control (PLC), for example, and transmitted to
the LECTOR
®
620 at defined intervals.
