Electronic Gears - Mitsubishi Electric MELDAS C6 Parameter Manual

7.4.2 Electronic Gears

The servo drive unit has internal electronic gears. The command value from the NC is converted into a
detector resolution unit to carry out position control. The electronic gears are single gear ratios
calculated from multiple parameters as shown below. However, each value (ELG1, ELG2) must be less
than 32767.
If the value overflows, the initial parameter error (alarm 37) or error parameter No. 2301 will be output.
If an alarm occurs, the mechanical specifications and electrical specifications must be revised so that
the electronic gears are within the specifications range.
<Semi-closed loop>
ELG1
=
ELG2 PIT x PC1 x IUNIT
<Closed loop>
ELG1 PGN x RNG2 x PC2
=
ELG2 30 x RNG1 x PC1
When the above is calculated, the following conditions must be satisfied.
ELG1 ≤ 32767
ELG2 ≤ 32767
