Machinery Such As Ceramics Conveyor Equipment
Positioning commands are executed by means of pulse output
instructions. Pulse output instructions normally output pulses from the
PLC, but pulses can be output to the error counter according to the
operand setting in the instruction (such as PLS2).
The amount of pulses input to the error counter is converted to a speed
command and output to the inverter. A command to the inverter is created
in the ladder program using this speed command (proportional to the
pulses remaining in the error counter). When RS-485 communications are
executed, ladder programming for communicating with the inverter is
created. When analog outputs are executed, ladder programming for
analog outputs is created.
When a run/stop command is executed for the inverter, the motor is
rotated and feedback pulses (for the amount of movement) are output from
the encoder to the CP1L. The error counter value is decremented by these
feedback pulses. The CP1L continues sending commands to the inverter
until positioning is completed. This enables accurate positioning to the
position output by the first position command.

command
High-speed counter
Calculations are made in
the ladder program based
on high-speed counter
values.
To avoid position error, positioning
must be stopped from a low speed.
Positioning becomes unreliable if
stopped from a high speed.
The deceleration position must
be calculated from the stop
position and the speed.
