(2) Timing chart
MD0
(Operation mode selection 1)
SON (Servo-on)
ST1 (Forward rotation start)
PI1 (Program input 1)
Program No.
Forward rotation
Servo motor speed
0 r/min
Reverse rotation
PED (Position end)
RD (Ready)
ALM (Malfunction)
Note. The detection of external input signals is delayed by the set time in the input filter setting of [Pr. PD29]. Considering the output
signal sequence from the controller and signal variations due to hardware, configure a sequence that changes the program
selection earlier.
