wrong.
Following takes channel 0 as example to describe how to modify current value:
(* Network 0 *)
(*Based on homing signal, hen it moves to homing, t requires to set current value as 100.*)
LD %SM0.0
PHOME 0, %M0.0, %M0.1, %M0.2, %VW0, %VW2, %VW4, %VD6, %VW10, %M0.4, %M0.5, %MB1
(* Network 1 *)
(*When PHOME instruction finishing, it uses finishing bit DONE to modify current value.*)
LD %M0.4
R_TRIG
MOVE DI#100, %SMD208
ST %SM201.4

PREL （ Relative position ） and PABS （ Absolute position ） will not change maximum output frequency when
it is executing . It will read the parameters minimum frequency, maximum frequency and
acceleration/deceleration time parameters when it starts, and calculates suitable acceleration/deceleration
segments according to the value of these parameters, then it will start outputting pulse. During pulse
outputting, PREL and PABS will not read the parameters above again, therefore, changing these parameters
will not affect the pulse output.
PJOG （ Jogging ） will read pulse input frequency(MAXF) all the time when it is executing, and adjust the
pulse output frequency according to new setting frequency.
PHOME （ Homing ） will read the maximum frequency (MAXF) all the time when it is running at maximum
frequency but hasn ’ t found homing signal, and calculate acceleration or deceleration segment automatically
according the new setting frequency, then it will accelerate or decelerate to new frequency to output pulse.
