Add the above instructions to the end of the program as a starting condition
for the ladder programming example. For error processing, refer to the ladder
program in 8-3-3 Modbus-RTU Easy Master Function and to the inverter’s
manual.

Positioning with
Trapezoidal Control
Specifications and
Operation
When start input CIO 1.04 turns ON, 600,000 pulses are output internally for
inverter positioning 0 to turn the motor shaft.
Note
Refer to 7-3-7 Determining the Internal Pulse Output Frequency for the for-
mula to convert the frequency and use the converted internal pulse frequency.
The number of output pulses is calculated from the encoder specifications
and the high-speed counter multiplier.
