№SR-ZSV00039 － 52 －Motor Business Unit, Appliances Company, Panasonic Corporation6－3 Electronic Gear SwitchingWith the following parameters, it is possible to switch between maximum of 4 numerators of the commandscaling by using DIV1 and DIV2.For the command scaling function, please refer to 4-2-2 “Command Scaling (Electronic Gear).”(1) Scope of application□This function is applicable only when the following conditions are satisfied:perating conditions for specified frequency division multiplication switching functionAction state  In Servo On status. Factors other than control parameters such as the deviation counter clear and com-mand pulse inhibition inputs and the torque limit are appropriately configured and donot cause any problem in normal motor rotation.(2) Related parametersCategory No. Parameter Setup range Unit Function0 08Command pulse countsper one motorrevolution01048576 PulseSpecifies the command pulse count corresponding to one revolution of themotor.If this setting value is “0” or in full-closed control, Pr0.09 “1st numerator ofelectronic gear,” Pr0.10 “Denominator of electronic gear,” Pr5.00 “2ndnumerator of electronic gear”, Pr5.01 “3rd numerator of electronic gear”, andPr5.02 “4th numerator of electronic gear”, are made valid.0 09 1st numerator ofelectronic gear0～1073741824 -To set the numerator used for the command scaling performed for thecommand pulse input.Is valid when Pr0.08 “Command pulse counts per one motor revolution “ is0.For position control, when the value is set to 0, the encoder resolution is setto the numerator. For full-closed control, when the value is set to 0, thecommand scaling ratio forcibly becomes 1:1.0 10 Denominator ofelectronic gear1～1073741824 -Specifies the denominator for scaling for a command pulse input.Is valid when Pr0.08 “Command pulse counts per one motor revolution “ is0.5 00 2nd numerator ofelectronic gear0～1073741824 -To set the 2nd numerator used for the command scaling performed for thecommand 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 setto the numerator. For full-closed control, when the value is set to 0, thecommand scaling ratio forcibly becomes 1:1.5 01 3rd numerator ofelectronic gear0～1073741824 -To set the 3rd numerator used for the command scaling performed for thecommand pulse input.Is valid when Pr0.08 “Command pulse counts per one motor revolution” is0.For position control, when the value is set to 0, the encoder resolution is setto the numerator. For full-closed control, when the value is set to 0, thecommand scaling ratio forcibly becomes 1:1.5 02 4th numerator ofelectronic gear0～1073741824 -To set the 4th numerator used for the command scaling performed for thecommand pulse input.Is valid when Pr0.08 “Command pulse counts per one motor revolution” is0.For position control, when the value is set to 0, the encoder resolution is setto the numerator. For full-closed control, when the value is set to 0, thecommand scaling ratio forcibly becomes 1:1.• The following table shows DIV1 and DIV2, and their corresponding numerators and denominators used for thecommand scaling.Command scalingＤＩＶ1 ＤＩＶ2 Numerator DenominatorＯＦＦＯＦＦ Pr0.09 Pr0.10ＯＮＯＦＦ Pr5.00 Pr0.10ＯＦＦＯＮ Pr5.01 Pr0.10ＯＮＯＮ Pr5.02 Pr0.10
