Memory used to temporarily store data. Before writing external data to the CPU module data memory, it is first
temporarily stored in the buffer memory to be used for operation by the program. The buffer memory is used by
the positioning module because the latest data can be read and written.
This is the basic data used in positioning. Parameters are determined by the machine side design, so
subsequent changes of parameters must be accompanied by changes in the machine design.
Data cannot be written during positioning.
The initial parameter values are written by the maker.
The turning ON and OFF of the current (voltage) for short periods.
A pulse train is a series of pulses.
The LD75 is the module that generates the pulses.
This is a device that generates pulses. Examples include devices installed on the motor shaft that create pulses
when the shaft rotates, and digital devices.
1-phase types output one pulse train. 2-phase types output two pulse trains with a phase difference. From 600 to
1,000,000 pulses can be output per shaft rotation. Generators with a ZERO signal function to output 1 or 2 pulses
per shaft rotation. Abbreviated as PLG.
Refer to the term "ENCODER".
There are two methods used to issue forward run and reverse run commands to the servomotor. The type used
differs according to the machine maker. In type A, the forward run pulses and reverse run pulses are output from
separate terminals.
In type B, the forward run pulses and reverse run pulses are output from the same terminal, and a
forward/reverse run identification signal is output from another terminal.

This is a method of using a returning pulse train to confirm whether the machine faithfully operated according to
the commands issued in automatic control. If the machine did not faithfully operate according to the commands,
a correction command is issued. For example, if a command is issued for 10,000 pulses, and a feedback pulse of
10,000 pulses is returned, then the balance becomes 0 and it can be judged that the command was faithfully
followed.
Refer to the term "DEVIATION COUNTER".
This is a pulse issued from the positioning module to a servomotor or stepping motor. Also called a command
pulse.
This battery-less memory can be used to store parameters and positioning data for backup.
Because it is battery-less, battery maintenance is not required.
About 100mm shorter in axial dimension than the standard motor.
Used when the servomotor is installed in a small space.
