13: Preset counting value arriving
Set up counting value of the drive‘s internal counter. The drive inputs counting
pulses via external terminals Xi (I=1~7), and the drive‘s internal counter
counts this signal. When the preset value arrives, Yi outputs an indication
signal. When the next external counting pulse signal arrives, Yi 's output
signal recovers, and the counter restarts to count again at the same time.

14: Specified counting value arriving
When Xi inputs external counting pulse signal and the counting value reaches
specified value defined by p6.17 (See Fig. 6-22), Y1 outputs an indication
signal, Y1 does not recover until specified value arrives.
As shown in Fig. 6-22, if P6.16=5, P6.17=3, when Xi inputs the 3th pulse, Y1
outputs an indication signal. When Xi inputs the 5th pulse, Y1 outputs
specified value arriving signal. Y1 will recover when the 6th pulse arrives.

15: Low voltage lockup signal
When DC bus voltage is lower than the low voltage limit, the panel LED
displays ―LU‖, and the terminal outputs indication signal at the same time.
