№SR-ZSV00039 － 15 －Motor Business Unit, Appliances Company, Panasonic Corporation4－2－2 Command Scaling (Electronic Gear)This function multiplies a pulse command value input from the controller by the specified scaling factor to use as a posi-tion command to the position control section. Using this function allows arbitrary setting of the motor revolution and dis-tance per unit input command pulse and increase of a command pulse frequency when the required motor speed cannot beobtained due to the limit to the controller pulse output capability. Related parametersCategory No. Parameter Setup range Unit Function0 08Command pulse countsper one motorrevolution01048576 pulseSpecifies the command pulse count corresponding to one revolutionof the motor.When this setting is 0, Pr0.09 "1st numerator of electronic gear" andPr0.10 "Denominator of electronic gear" are valid.This setting is invalid in full-closed control.0 09 1st numerator ofelectronic gear01073741824 Specifies the numerator for scaling for a command pulse input.Valid when Pr0.08 "Command pulse counts per one motor revolution"is 0 or in full-closed control.When this parameter is set to 0, the encoder resolution is set to thenumerator for position control, and for full-closed control, thecommand scaling ratio becomes 1:1.0 10 Denominator ofelectronic gear11073741824 Specifies the denominator for scaling for a command pulse input.Valid when Pr0.08 "Command pulse counts per one motor revolution"is 0 or in full-closed control.The relationships between Pr0.08, 0.09, and 0.10 in position controlPr0.08 Pr0.09 Pr0.10 Command scaling11048576 (No effect)(No effect) * The process shown in the above diagram is executed inaccordance with the set value of Pr0.08, regardless of set-tings of Pr0.09 and Pr0.10.0 11073741824* When the set value of both Pr0.08 and Pr0.09 is 0, theprocess shown in the above diagram is executed in accor-dance with the set value of Pr0.10.011073741824 11073741824* When the set value of Pr0.08 is 0 and that of Pr0.09 is not 0,the process shown in the above diagram is executed in ac-cordance with the set values of Pr0.09 and Pr0.10.PositioncommandEncoder resolution *1Commandpulse input[Set value of Pr0.08]Positioncommand[Set value of Pr0.10][Set value of Pr0.09]Commandpulse inputEncoder resolution *1 Positioncommand[Set value of Pr0.10]Commandpulse input
