Chapter VI Specified Function Introduction
111
When you choose even parity or odd parity, the actual bits of every byte is 11. Among
them, the one is start bit, 8 data bits, 1 check bit and 1 stop bit. When you choose no
parity, the actual bits of every byte are also 11. 1 start bit, 8 data bits and 2 stop bits.
Function Description:
The value of function codes may often be modified when communication is used.
Many save values of function codes in EEPROM will be updated while the function
codes’ value has been changed. Frequent erasing and writing on EEPROM will reduce
its service life. When there’s no need to save function data via communication, we can
set P07.05 to 0 to prohibit saving data to EEPROM to prolong its service life. .
Please refer to the relevant instructions in attachment to see the application methods of
MODBUS Communication.
6.9 Parameters of Origin Search and Multistage Position (Group
P10)
Origin Search Function Setting
(1) Function Description
The origin search function in position mode (P00.02=0) refers to the origin searching
function accomplished by the servo driver. . The process of origin search as shown
below is divided into two stages:
(a) When the origin search function of servo driver is enabled in servo on condition, the
motor can search the decelerating point in the direction of deceleration point target at
specified high search speed (P10.03) under the origin search mode（P10.02）. Then slow
down at given deceleration time (P10.05) to zero speed after meeting the rising edge of
origin switch signal (OrgNear).
