5. SPECIFICATION AND FUNCTION
(1 )Specification
Ordering Number ・・・・Ａ８６０－０３３３－Ｔ７０１
Current Consumption ・・２５０ｍＡ MAX.
(2) Function
High Resolution Serial Output Circuit H consists of a circuit which automatically cancels
offset voltage of analog input signals and interpolates to 2048 divisions and driver receiver
circuit which communicates with CNC.
(3)Alarm detection function for CMAL（Count Miss Alarm） and setting pin “SW1”
This circuit has a function of detecting CMAL (Count Miss Alarm), by checking position
data and reference signal. CMAL occurs when the data of the position data where the
reference signal is detected is different from the position data where the reference signal
was detected first after power on. So, it is recommended that there is one reference signal
in the encoder.
When the setting of “SW1” is “A”, the above function is valid. When “B”, the function is
invalid, and the alarm will not occur even if there are plural reference signals. And , the
required reference signal must be detected first after the power is on.
“A” is set for “SW1” by using shorting pin at shipping.
(4)Interface of reference signal and setting pin “SW2”
This circuit can receive two types of reference signal interface. When the setting of “SW2”
is “A”, analog type reference signal can be received. When “B”, digital type (RS-422 or
RS-485) can be received.
“A” is set for “SW2” by using shorting pin at shipping.
