FM 260: Frequency Multiplier for Incremental Encoder Signals
|
|
This universal impulse and frequency multiplier provides one encoder input and one encoder output, both
using channels A, /A, B, /B, Z, /Z with programmable levels and characteristics.
The unit provides error-free multiplication of an input frequency by a proportional factor F1 and a
reciprocal factor F2, both adjustable in a range of 0.0005 to 9.9999. The result appears at the frequency output :
- More properties:
-
Index and marker pulse generator: The unit generates an index pulse with a programmable impulse distance, which - if required - can be synchronized with the input
marker pulse.
- All operation modes provide error-free frequency conversion, with full consideration of the
A / B phase and direction of the quadrature signals, therefore no cumulative errors.
- Max. frequency 1 MHz on input and output, Power supply 18 – 30 VDC
- RS232 interface and USB port, optional PROFIBUS-DP interface available
