Mode 0 of ACC(––) cannot be used if the PC Setup (DM 6611) is set to high-
speed counter mode.
P must be 001 or 002 and M must be 000 to 003.
C to C+3 must be in the same data area.
ACC(––) can be used with the functions listed in the following table.
Unit/Board
Pulse I/O Board
ACC(––) is used together with PULS(65) to control the acceleration and/or
deceleration of pulses output from port 1 or 2. The 4 available modes are
described briefly below.
The function of the control words varies in the 4 modes, but P always specifies
the port where the pulses will be output and M always specifies the mode. Set
P=001 or 002 to indicate port 1 or 2. Set M=000 to 003 to indicate modes 0 to
3.
Note Refer to 1-5 Pulse Output Function for more details.
Mode 0 is used to output a specified number of CW or CCW pulses from port
1 or 2. The acceleration rate, frequency after acceleration, deceleration point,
deceleration rate, and frequency after deceleration can all be controlled.

PULS(65) Operand Settings
PULS(65) must be executed before ACC(––) in order to specify direction, the
total number of pulses to be output, and the deceleration point. The function
of PULS(65) operands are described below. Refer to 5-28-9 SET PULSES –
PULS(65) for more details.
1. The first operand of PULS(65) specifies the output port. Pulses are output
from port 1 when P=001, and from port 2 when P=002.
IR, SR, AR, DM, EM, HR, LR
Pulse outputs 1 and 2
(In order to use ACC(––) mode 0, ports 1 and 2 must be set sim-
ple positioning mode in DM 6611 of the PC Setup. ACC(––) can-
not be used if the mode is set to high-speed counter mode.)
