Brief Description
Features
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
• up to 2 probe inputs per axis, depending on hardware design of control
section (CSH..., CSB..., CDB...)
• measuring signals can be actual position values of motor encoder,
external encoder or measuring encoder, in addition master axis
position values or cam shaft profile values
• measurement of absolute actual position values, of actual position
value differences, detection of time intervals between measuring
signals
• measurement triggered by positive and/ore negative probe signal
edges
• single measurement or continuous measurement to be selected,
measurement events are counted in the case of continuous
measurement
• position value range ("expectation window") can be defined within
which measurement can take place (activation of a "failure counter"
when expectation window is passed through without measuring event)
• sampling time for probe signals approx. 0.05 µs
(For sufficient noise immunity, signal edge change must last for at
least 4.0 µs in order to be detected!)
Hardware Requirements
The probe signals can only be evaluated as measured value trigger by
"rapid" digital inputs. The hardware design of the control section
determines the number of available "rapid" digital inputs.
The following control section designs are available:
• no rapid digital input:
CSB01.1N-FC-... → BASIC OPENLOOP
CSB01.1N-AN-... → BASIC ANALOG
• one rapid digital input:
CSB01.1N-SE-... → BASIC SERCOS
CSB01.1N-PB-... → BASIC PROFIBUS
→ BASIC UNIVERSAL (single-axis)
CSB01.1C...
• one rapid digital input per axis:
→ BASIC UNIVERSAL (double-axis)
CDB01.1C-...
• two rapid digital inputs:
→ ADVANCED
CSH01.1C-...
The terminal designations of the "rapid" digital inputs are contained in the
documentation "Project Planning Manual for Control Sections".
Pertinent Parameters
• S-0-0130, Probe value 1 positive edge
• S-0-0131, Probe value 1 negative edge
