Generates clock pulse through high-
speed counter CTH0.
Counts clock pulese through high-
speed counter CTH1.
• CTC0: Pulse cycle
CTC1: Pulse width
• CTC2: Frequency change point
CTC3: Positioning pulse total
count
Sets parameters (DM0000 to
DM0003).
Reverse output
Emergency stop
Sets CTC0.
Setting value of CTC0 =
1 ÷ DM0012 x 10
3 x 10 3 ÷ 6.4
Sets CTC2.
• DM0010: Pulse cycle T (µs) x 10
• DM0011: Accumulated pulse count
• DM0012: Current frequency f [Hz]
• 1200: Acceleration flag
