Special Instructions Section 5-26
!Caution With PLS2(––), conditions such as acceleration/deceleration speed and the
target speed can cause low-speed pulse output (100 Hz) to continue for an
extended period of time when stopping. Even when this happens, the correct
number of pulses will be output.
Correct the system by adjusting the acceleration/deceleration speed and/or
the target speed, or by using the ACC(––) instruction (mode 0) to increase the
speed (deceleration target frequency) when stopping.
5-26-12ACCELERATION CONTROL – ACC(––)
Limitations This instruction is available in the CQM1-CPU43-E/-EV1 only.
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.
Description 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 1-3 Pulse Output Function (CQM1 Only) for more details.
