Entering from PC Loader
Use the "Mechanical settings calculation(T)" button provided at the lower part of the parameter
editing screen (PA1: Basic setting) of PC Loader to specify the electronic gear simply.
[Example of calculation of electronic gear ratio]
To connect the ball screw (lead 10 mm) directly to the output shaft of the servomotor and set the
unit amount at 1/100, the number of encoder pulses (20 bits) is 1048576 rev.
Therefore numerator 0 and denominator of the electronic gear are 131072 and 125, respectively.
If the traveling amount of the mechanical system per
servomotor revolution includes , you can approximate
to 355/113.
The number of output pulses is irrelevant to command
pulse correction.
A / B phase pulse in B-phase advance are output
according to the reference value of PA1_08 (number
of output pulses per revolution) during forward rotation of the motor shaft.
Enter the specifications of the
machine to automatically
calculate the settings.
Parameters grouped according
to each mechanical
configuration helps you enter
