13. POSITIONING MODE
2) Program example 2
If the travel distance of the "ITP" command is less than the travel distance necessary for deceleration,
the actual deceleration time constant becomes less than the set value of the "STB" command.

(f) External pulse counter (COUNT)
When the number of input pulses of the manual pulse generator becomes greater than the value set
with the "COUNT" command, the next step is started. Set "0" to erase the accumulated input pulses.
Program
COUNT(500) The next step is held until the number of input pulses of the manual pulse generator reaches 500 [pulses]. a)
SPN(500) Speed (Motor speed)
STA(200) Acceleration time constant
STB(300) Deceleration time constant
MOV(1000) Absolute move command
TRIP(500) Trip point
COUNT(0) Cumulative input pulses are cleared.
