Parameter
Pulse train form type selection (Pr. 428, NP signal)
● Set "2" (conditional pulse train position command) in Pr. 419.
● Set "68" in Pr. 178 to Pr. 189 "Input terminal function selection" to assign conditional position
pulse train sign (NP).
● Select command pulse train using Pr. 428.

Tab. 6-24: Setting of parameter 428
● Select vector control, then select position control.
NOTE When Pr. 419 "Position command source selection" = 2 (conditional pulse train position
command), JOG terminal serves as conditional position pulse train input terminal regardless
of the Pr. 291 "Pulse train input selection" setting.
Selection of clear signal (Pr. 429, CLR signal)
● Use this function to zero the droop pulse for home position operation, etc.
● When "0" is set in Pr. 429, the deviation counter is cleared at the edge of turning on of the
clear signal (CLR). In addition, the CLR signal turns on in synchronization with zero pulse
signal of the encoder at home position operation, etc., deviation counter is cleared.
● For the terminal used for CLR signal, set "69" in any of Pr. 178 to Pr. 189 "Input terminal
function selection" to assign the function.
