*P1.05
Number of command input pulses per revolution
Default value
0
Setting range
0: Electronic gear (P1.06/07) is enabled
64~1048576 [pulse]: This
parameter setting is enabled
The parameter is enabled only under position control
Enter the number of command pulses necessary to rotate the servo motor a full turn.
When the default value (“0”), the settings of P1.06 and 07 (electronic gear numerator and denominator) are
enabled.
P1.06
Numerator 0 of electric gear
Default value
16
P1.07
Denominator of electric gear
Default value
1
Setting range
1~4194304
These parameters are enabled only under position control.
With these parameters, the traveling amount of the mechanical system per each command pulse is adjusted
to a unit amount.
Calculate according to the following equation:
· Equation of numerator 0 of electronic gear and denominator of electronic gear
Cancel down so that numerator 0 divided by the denominator of the electronic gear is an integer (65535 or
less).
* The unit amount is the machine travel amount to one command pulse. Its unit is [unit].
(mm/pulse, degree/pulse=[unit])
【
Calculation example of electronic gear
】
To connect the ball screw (lead 10 mm) directly to the output shaft of the servo motor and set the unit
amount at 1/100, the number of encoder pulses (17 bits) is 131072 rev
