Electronic Gear Switching - Panasonic Minas-LIQI Series Technical Reference

6－3 Electronic Gear Switching
With the following parameters, it is possible to switch between maximum of 4 numerators of the command
scaling by using DIV1 and DIV2.
For the command scaling function, please refer to 4-2-2 "Command Scaling (Electronic Gear)."

Specifies the command pulse count corresponding to one revolution of the
motor.
If this setting value is "0" or in full-closed control, Pr0.09 "1

Pr5.02 "4 numerator of electronic gear", are made valid.
To set the numerator used for the command scaling performed for the
command pulse input.
Is valid when Pr0.08 "Command pulse counts per one motor revolution " is
0.
For position control, when the value is set to 0, the encoder resolution is set
to the numerator. For full-closed control, when the value is set to 0, the
command scaling ratio forcibly becomes 1:1.
Specifies the denominator for scaling for a command pulse input.
Is valid when Pr0.08 "Command pulse counts per one motor revolution " is
0.
nd
To set the 2 numerator used for the command scaling performed for the
command pulse input.
Is valid when Pr0.08 "Command pulse counts per one motor revolution"is 0.
For position control, when the value is set to 0, the encoder resolution is set
to the numerator. For full-closed control, when the value is set to 0, the
command scaling ratio forcibly becomes 1:1.
rd
To set the 3 numerator used for the command scaling performed for the
command pulse input.
Is valid when Pr0.08 "Command pulse counts per one motor revolution" is
0.
For position control, when the value is set to 0, the encoder resolution is set
to the numerator. For full-closed control, when the value is set to 0, the
command scaling ratio forcibly becomes 1:1.

To set the 4 numerator used for the command scaling performed for the
command pulse input.
Is valid when Pr0.08 "Command pulse counts per one motor revolution" is
0.
For position control, when the value is set to 0, the encoder resolution is set
to the numerator. For full-closed control, when the value is set to 0, the
