5.7 Checking the signal levels (menu )
The signal levels of the encoder can be checked in this menu�
Evaluation of the signals from sinewave encoders can only be performed to a limited
extent, since the differential signals from the encoder are converted into TTL signals� It is
therefore not necessary to check the levels�
At standstill, the momentary HIGH (
H ) and LOW ( L ) levels of the encoder signals will be
displayed. If the level is undefined or there is no corresponding signal (open input), then
the ‘
?
’ symbol will appear�
When the encoder is rotating, correct signal levels will be acknowledged by a ‘
√
’ mark�
5.8 Display measurements as text (menu )
In menu the following measurements are displayed as text, see also section 7.2.3,
page 20 :
Display 1: Speed in revolutions per minute (
+00072 rpm
)
For encoders that provide two signals in quadrature (K1 and K2, with a 90° phase shift),
the mathematical sign determines the direction of rotation� For encoders with a single K1
signal output, only the magnitude is shown�
Display 2: Pulse/pause ratio of the K1 signal (
K1=50:50
)
The first figure indicates the duration of the high level as a percentage of the entire cycle.
The second figure indicates the duration of the low level of the K1 signal, as a percenta -
ge�
Display 3: Pulse/pause ratio of the K2 signal (
K2=48:52
)
The first figure indicates the duration of the high level as a percentage of the entire cycle.
The second figure indicates the duration of the low level, as a percentage.
)
Please note:
Principle limitations mean that the pulse/pause ratio will be affected during rapid
acceleration�
Display 4: Angular position (
A=29.0°
)
Display of the angular position, in degrees�
Display 5:
Phase shift between K1 und K2 (
P=089°
)
The displayed value is the phase shift (in degrees) between the rising edge of the K1
signal and the rising edge of the K2 signal�
)
Please note:
If the pulse/pause ratio of the encoder signals K1 and/or K2 is other than 50:50,
then there will be different values measured for the phase shift between K1 and K2,
depending on the rotating direction�
Principle limitations also mean that the calculation of the phase shift will be affected
during rapid acceleration�
