Introduction
The BY 125 is a cost-effective synchronizer for high performance synchronization and
registration applications between two independent drives, with a convincing value for price
ratio. The units are suitable for any kind of drives (AC, DC, Servo etc.) that are variable in speed
under control of a 0-10 volts speed reference. The 80 kHz counting frequency allows use of
high-resolution encoders even with high operation speeds. Due to the very short response time
of 120
μ
sec only, the unit also provides a proper synchronization under highly dynamic
conditions with servo drives.
When on the slave site you use a 1-quadrant-type drive (speed reference always with positive
polarity 0...+10 volts), and your drive uses digital forward/reverse select inputs, please see
“Option UP125” and observe the special hints given in section 18 of this manual.
As a matter of course, full ratio control and other functions like index pulse tracking, print mark
registration and remote phase control are included in the wide set of standard functions.
All settings are fully digital and no potentiometer adjustments are necessary. Programming of
parameters is accomplished by PC/Laptop, using our operator software OS3.x (CD included in
delivery). Remote control is possible by serial communication, e.g. with use of one of our
operator terminals TX720 or BT348. PROFIBUS control is possible with use of the PB251
gateway (see “accessories”)
The mechanical construction uses a closed 19" steel cassette with all connections on its front.
Rack mounting of the cassette therefore does not require use of a swivel frame.
Use of our SM 150 back plane (option) also allows easy DIN rail mounting.
The BY 125 operates from an unstabilized 24 VDC supply (18 V... 30V).
