5.3.3.6 Set segment thorugh communication 
Set the segment 
number through 
communication 
If this parameter is set to a certain segment number, this segment position will be executed without 
step change signal. Communication can be used to modify parameters. 
For example: to execute the second segment position, set F2-09 = 0, and then F2-09 = 02. 
5.3.3.7 Motion start signal (/MRUN) 
Terminal  output  is  not 
assigned by default. 
It is only valid in the internal 
position  mode,  similar  to  the 
positioning  completion  signal 
in  the  external  pulse  mode; 
there is output when the motor 
is  running,  and  there  is  no 
output when the motor stops. 
Parameter  range  0000-0018, 
assigned to the output interface 
through parameter P5-50. When 
it  is  set  to  0001,  the  signal  is 
output from SO1 terminal.

Soft start acceleration and deceleration time is suitable for mode 3/4/7. Smooth speed control can be 
carried out when step speed instruction is input or internal setting speed is selected.
