GENERAL PARAMETERS TAB
• R
ANGE±: measurement range of the encoder or line.
• T
YPE OF INTERFACE: DIGITAL / COUNTER/ ANALOGUE
• TYPE OF SENSOR :
• L
INEAR:
to be used for linear positioning transducers (optical scales typically).
• ROTARY:
to be used for angular positioning transducers (rotary encoders
typically), when an information is required about both the number of
revolutions made and the position within the lap.
• PERIODICAL:
to be used for angular positioning transducers (rotary encoders
typically), when an information is required only about the position within the
lap, but not about the number of revolutions made (for example in
applications concerning spindles).
• STEP: It defines the variation (in the measuring unit mentioned above) against a
S
TEP of the sensor. For example:
- if a scale with 20 μm step is used, 20 has to be programmed
- if an encoder featuring 7200 step/rev is used, 0.05 has to be programmed
(360°/7200=0,05 °/step)
• M
AX. FREQUENCY: defines the maximum frequency of the signal generated by
the sensor (expressed as P
ULSES-STEPS per second), if the frequency exceeds
this value an error signal is generated and the counter is decalibrated. The ma-
ximum value depends on the T
YPE OF INTERFACE:
- D
IGITAL AND COUNTER: 2500 Ksteps per second
- A
NALOGUE: 250 Ksteps per second
• R
EAL FREQUENCY: in this column the control frequency is displayed, which the
hardware is able to deploy against the programmed value of the parameter M
AX
F
REQUENCY.
• T
YPE OF CALIBRATION:
• O
N CURRENT POS.: the transducer value becomes the value programmed in
the parameter Marker Position when the zeroing command is received.
• N
ONE: No calibration is foreseen.
• T
EST ON MARKER: It enables the input of the reference signal I or M (and the
related connection checks)
ANALOGUE TAB
• A
MPLITUDE TOLERANCE (%): It defines the maximum percentage variation al-
lowed for the amplitude of the resulting of the signals A and B, i.e. (A
2
+ B
2
)
1/2
• AMPL. CHECK ENABLE: It enables the control described in the previous point
• O
FFSET A: Offset value of the channel A, normally calculated by the specific
calibration utility
• O
FFSET B: Offset value of the channel B, normally calculated by the specific
calibration utility
• A
MPLITUDE A: Amplitude of the signal of channel A, normally calculated by the
specific calibration utility
