Pulse Outputs
Section 5-3
ACCELERATION
CONTROL: ACC(888)
Use ACC(888) to set the target frequency and acceleration and deceleration
rate and output pulses with acceleration and deceleration. (Acceleration rate
is the same as the deceleration rate.)
Either independent mode positioning or constant mode speed control is possi-
ble when used in combination with PULS(886). ACC(888) can also be exe-
cuted during pulse output to change the target frequency or acceleration/
deceleration rate, enabling smooth (sloped) speed changes.

Pulse output method (See note.)
0 hex: CW/CCW
1 hex: Pulse + direction
Bits 12 to 15 Not used. (Always 0 hex.)
F
First pulse frequency
word
F and F+1 contain the pulse frequency setting, in units of
1 Hz. (F contains the rightmost 4 digits and F+1 contains
the leftmost 4 digits.)
X/XA CPU Units:
Unit version 1.1 and later:
• Pulse outputs 0 to 3:
00000000 to 000186A0 hex (0 Hz to 100 kHz)
Unit version 1.0 and earlier:
• Pulse outputs 0 and 1:
00000000 to 000186A0 hex (0 Hz to 100 kHz)
• Pulse outputs 2 and 3:
00000000 to 00007530 hex (0 Hz to 30 kHz)
Y CPU Units:
• Pulse outputs 0 and 1:
00000000 to 000F4240 hex (0 Hz to 1 MHz)
• Pulse outputs 2 and 3:
00000000 to 000186A0 hex (0 Hz to 100 kHz)
