When the voltage of the absolute encoder battery
becomes 3.2V or less, the low-voltage warning of
the absolute encoder battery will occur. Please
change your battery when this warning is seen.
When the internal condenser voltage of the
encoder is about 2.8V or less, the absolute encoder
internal low-voltage alarm will go off. When this
alarm goes off, the memorized information in the
encoder can disappear.
The drive transmits the absolute information through the PS, EA, EB
terminals.
The data structure transmitted to the controller through the output is
shown below.
Transmission Frame Structure
STX represents the beginning of the transmission packet and
corresponds to ASCII code 02H. ETX represents the end of the
transmission packet and corresponds to ASCII code 03H.
The range of
the multi-revolution data is -32768 to +32767, and if it exceeds –32768,
it b32767, and if it e32767, it becomes -32768. The
range of multi-revolution data of compact
(H) type is -4096 to + 4095.
