Signal type
You can choose from the following signal types (Page 67):
Symbol
Signal type
Meaning
Additional option-specific
parameters
Incremental encoder (A, B
phase-shifted)
An incremental encoder with phase-shifted A
and B signals is connected.
• Invert direction
• Signal evaluation
• Filter frequency
• Sensor type or Interface
standard
Incremental encoder
(A, B, N)
An incremental encoder with phase-shifted
signals A and B and a zero signal N is con-
nected.
• Invert direction
• Signal evaluation
• Filter frequency
• Sensor type or Interface
standard
• Reaction to signal N
• Frequency
Pulse (A) and direction (B) A pulse encoder (signal A) with direction
signal (signal B) is connected.
• Filter frequency
• Sensor type or Interface
standard
Pulse (A) A pulse encoder (signal A) without direction
signal is connected. You can specify the
count direction by means of the control inter-
face (Page 185).
• Filter frequency
• Sensor type or Interface
standard
Count up (A), count down
(B)
Signals for counting up (signal A) and down
(signal B) are connected.
• Filter frequency
• Sensor type or Interface
standard
Invert direction
You can invert the counting direction to adapt it to the process.
The inverting of the direction is configurable and active for the following signal types:
● Incremental encoder (A, B phase-shifted)
● Incremental encoder (A, B, N)
