Inverter Positioning
Section 5-3
• MODE CONTROL (INI)
Port: Inverter positioning, stopping inverter positioning
• HIGH-SPEED COUNTER PV READ (PRV)
Port: Inverter positioning, Operation: Reading error counter, inverter posi-
tioning status, or error counter present value
■
Automatic Calculation of Inverter Frequency Commands
• For either serial communications or an analog output, the power supply
frequency per motor revolutions/s, the number of encoder pulses per
motor revolution, and the error counter calculation cycle can be set in the
PLC Setup to automatically calculate the inverter frequency command
values and store it in A23/A33 in increments of 0.01 Hz.
• For serial communications, the ladder program is used to output the value
in A23/A33 to the inverter using serial communications.
• For analog output, the value in A23/A33 can be scaled to analog output
values and output from the Analog Unit to the inverter.
■
Forward/Reverse Operation Commands, Stopping Commands, Etc.
• The Forward Command Flag (A26.01/A36.01) and Reverse Command
Flag (A26.02/A36.02) can be used as input conditions for forward and
reverse operation commands.
• The Operation Command Flag (A26.00/A36.00) and In-position Flag
(A26.03/A36.03) can be used as input conditions to execute scaling to
inverter frequency commands and to execute stop commands.

Instruction Specifications
The normal pulse output instructions are used (PLS2, PULS + SPED, or
PULS + ACC). One of the inverter positioning ports is specified as the port for
the instruction. Just like pulses are output externally for the normal pulse out-
put instructions, error counter pulses are accumulated in the internal error
counter when executing inverter positioning.
Port Designation
Operand
Specifications
When executing pulse output instructions or status read instructions for
inverter positioning, a port number for inverter positioning is specified for the
port operand of the instruction. The following values are used.
0020 hex: Inverter positioning 0
0021 hex: Inverter positioning 1
When reading the present value of inverter positioning, use the following val-
ues to specified the port number for inverter positioning.
0030 hex: Inverter positioning 0 (signed)
0031 hex: Inverter positioning 1 (signed)
