Bits 8 to 11
Bits 12 to 15 Not used. (Always 0 hex.)
F First pulse frequency
word
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.

Mode
0 hex: Continuous
1 hex: Independent
Direction
0 hex: CW
1 hex: CCW
Pulse output method (See note.)
0 hex: CW/CCW
1 hex: Pulse + direction
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.)
