Pulse Output with Trapezoidal Acceleration/Deceleration and Separate
Acceleration/Deceleration Rates
The only limitation that exists is that ACC(––) (ACCELERATION CONTROL)
in Mode 0 (Acceleration + Independent) cannot be used in High-speed
Counter Mode.

The setting in DM 6611 is read only when the CQM1H is started. If this setting
is changed, the PC must be turned OFF and ON again to enable the new
value.
Operation Settings for Ports 1 and 2 (DM 6643 and DM 6644)
The diagram below shows how port 1 (DM 6643) and port 2 (DM 6644) are
set to perform fixed duty factor pulse output, which is the default pulse output
format. The settings for ports 1 and 2 can differ.

Port 1 Pulse Type
0: Fixed duty factor pulse output
Set to fixed duty factor when per-

Default: 0
(Fixed duty factor pulse output)
Variable duty factor pulses cannot be output from a port if it has been set to
perform standard pulse output.
The following examples show programs that controls pulse output from ports
1 and 2. Before running the programs, check that the settings in the PC Setup
are as follows:
DM 6611: 0001 (Simple Positioning Mode)
DM 6643: 0000 (Fixed duty factor pulse output from port 1)
DM 6644: 0000 (Fixed duty factor pulse output from port 2)
