Signal outputs for pulse rates (square wave pulses)
Basic version
Basic channel 0° (A) and pulse channel 90° (B)
Internal system diagnostics with error
output (ERROR)
Each with inverted signals
Option N
Reference pulse (N) mechanically defined; one
square-wave pulse per revolution; with inverted
signal
Option 2F
Twice as many pulses as basic channel by
combining the 0° and 90°channels
Option B
Rapid direction of rotation detection at each edge
of the 0° and 90°channels
Can be combined with Option F
Option B2
Rapid direction of rotation detection at each edge
of the 0° and 90° channels; additional standstill
recognition
Option B3
Rotation-dependent output signals. This option
supports counter cards with separate UP/DOWN
pulse inputs. Basic channel signals are issued at
option output 1 when rotation is clockwise and at
option output 2 when rotation is counterclockwise.
Option S
Electronic overspeed switch with two
independently programmable switching points

Fiber optic option
As an alternative to conventional signal
transmissions via copper cables encoder signals
can also be transmitted via fiberoptic cables.
Max. frequency 100 kHz
The signal sequence 0°, 90° applies for clockwise rotation seen from the drive shaft direction.
To obtain the same signal sequence for counter clockwise rotation the clamp 0°, 90° has to be
connected see connection diagram.
