2.1. Operation as Signal Converter
The conversion output generated from the analogue input is available with following formats:
Frequency
The unit converts the analogue input into a proportional output frequency with a free
programmable range between 0,01 Hz and 1 MHz. A full set of impulse channels A, /A,
B, /B, Z, /Z is available and the direction information (A, B, 90°) automatically considers
the actual state and course of the analogue input with regard to the related parameter
settings. An external voltage connected to terminal [Com+] defines the output voltage
level (range 5 - 30 V). Where no remote voltage has been applied (Com+ unconnected),
the unit automatically provides a 4 volts output (TTL compatible).
Linear or angular position with incremental representation
The unit converts the analogue input into a positional or angular information similar to
an incremental encoder. This means that e.g. the rotation angle of an analogue
potentiometer shaft converts to real incremental encoder information. The unit provides
a full set of output channels A, /A, B, /B, Z /Z, and the directional information (A, B, 90°)
fully follows the mechanical motion of the potentiometer. The impulse level on the
incremental output is determined by the remote voltage applied to terminal [Com+]
(range 5 - 30 V). When no external voltage is applied (i.e. terminal Com+ unconnected)
the unit automatically generates a 4 volts signal swing (TTL compatible).
Linear or angular position with absolute SSI output
The unit converts the analogue input into a positional or angular information similar to
an absolute encoder with SSI interface. This means that e.g. the rotation angle of an
analogue potentiometer shaft converts to real SSI encoder information. Similar to a real
SSI encoder the UZ 210 converter always acts as a “Slave” responding to the clock
signal of a remote SSI master unit. All SSI signal levels are in line with the common SSI
standard (TTL-differential or RS422 respectively).
Serial and USB
At any time and with all modes of operation the conversion result of the unit is
accessible by PC or PLC, via the serial interface or by the converter’s USB port
2.2. Operation as Frequency or Position Generator
(Motorized Potentiometer Mode)
With this mode of operation the unit functions similar to a motorized potentiometer or to a
digital positioning axis.
In frequency mode the unit generates a scalable frequency output where the frequency can be
adjusted via remote commands „UP“ (increase) and „DOWN“ (decrease). In positioning mode
the unit generates quadrature counting impulses in forward or reverse direction, under control
of the „UP“ and „DOWN“ commands (virtual positioning axis).
Moreover the unit provides a „Repeat“-Function for cyclic execution of frequency or position
curves within programmable limits.
