IF52
1.3 Mechanical safety
•
Install the device following strictly the information in the section “4 -
Mounting instructions” on page 4;
•
do not disassemble the unit;
•
do not tool the unit;
•
delicate electronic equipment: handle with care; do not subject the
device and the shaft to knocks or shocks;
•
respect the environmental characteristics of the device.
2 - Identification
Device can be identified through the
order code
and the
serial number
printed
on the label applied to its body. Information is listed in the delivery document
too. Please always quote the ordering code and the serial number when
reaching Lika Electronic for purchasing spare parts or needing assistance. For
any information on the technical characteristics of the product, refer to the
technical catalogue.
3 - Introduction
IF52 is the small, low-cost yet high-performing converter for industrial
applications suitable for use in installations where the information delivered by
a sensor or an encoder fitted with SSI interface needs to be converted into a
parallel signal or a serial RS-232 data format. It is also possible to convert serial
RS-232 data into a parallel format.
The unit has been designed as a compact module with 12 screw terminals and
two 9-position and 25-position D-SUB connectors (female). The housing is
suitable for standard DIN rail mounting (according to EN 60715 standard).
Applicable encoders and sensors
Single-turn or multi-turn absolute encoders and all similar sensors using a
standard SSI interface (6 to 25 bits of resolution with binary or Gray code)
can be connected to IF52. The unit can operate in either Master mode (clock
signal is generated by IF52 unit) or in Slave mode (clock signal is generated
by a remote device).
Remark about encoder resolution
The unit provides settings for the standard resolutions of 13 bits, 21 bits and
25 bits. As a general rule, for sensors with other resolutions you can use the
next higher setting (i.e. set the unit to 21 bits when you use a 16-bit sensor).
Depending on the brand and specification of the encoder, in some cases it
may be necessary to blank out the surplus bits by using the bit blanking
function described later, see “Hint for the use of the bit blanking function”
on page 46. Anyway, generally the unit works properly even without special
bit blanking.
