How to modify current value
Each high speed output channel has one register for current value, they are SMD212,SMD242
and SMD262.The outputted pulse number are stored in these registers. Current value registers
are read only, if user needs to modify the current value, it can use following methods.
 Method 1
User reset bit to clear current value.
The reset bits for 3 output channels are SM201.6
、
SM231.6 and SM251.6.
When the reset bit is 1, PLC will set the current value as 0.Therefore, t only needs one
scan time for the reset bit to activate. When it needs to use this bit, try to avoid to keep this bit
always 1 and also and also avoid to set this bit while the Position Control instruction (Include
PHOME, PREL, PABS, JOG and PFLO_F) is executing, otherwise the counting value may be
wrong.
Following takes channel 0 as example to describe how to reset current value.
(* Network 0 *)
(*Based on homing signal, when it moves to homing, it requires to clear current value*)
