Functions Compatible with Servo Drivers with Absolute Encoders
Section 7-8
7-8-3 Data Format of Absolute Encoder Output
The format of data from a servo driver with an absolute encoder compatible
with the unit (model CS1W-HCA12-V1) is as follows:
Serial Data Specification
Data Format
Note 1. “P" of ASCII code. It is 50 Hex in hexadecimal.
2. The range of No. of rotations that can be received by the unit is between
+65535 to
-
65535.
3. For details of the data on the number of multi-turns received from a servo
driver, please check the manual of the servo driver in use.
4. Please set the unit function setting "high-speed counter 1 operating mode
(DM 6605)" to either ABS linear (CW
-
) or ABS linear (CW+) mode corre-
sponding to the setting of reverse rotation mode on the servo driver in use.
