PA1_08 Number of output pulses per revolution
No.
Name
Number of output
08
pulses per
revolution
Enter the number of pulses output per motor rotation from pulse output terminal (FFA, *FFA, FFB and
*FFB).
(The output pulse value is deducted -2bit from encoder resolution.)
If the reference value is other than 0, the Z-phase output synchronizes with the A-phase output, and an
output having the same pulse width as that of the A-phase is obtained.
With default value "0," settings of parameters PA1_09 and _10 (The output pulse value is deducted
-2bit from encoder resolution.) are followed.
PA1_09 Numerator of electric gear for output pulses
PA1_10 Denominator of electric gear for output pulses
No.
Name
Numerator of electric gear for
09
output pulses
Denominator of electric gear for
10
output pulses
Specify the ratio of the output pulse per revolution of the servomotor.
If parameter PA1_08 is "0," settings of these parameters are enabled.
Calculate according to the following equation. (The output pulse value is deducted -2bit from encoder
resolution.)
Specify "1/32" to output 131072 (4194304 × 1/32) A-phase and B-phase pulses per revolution.
The Z-phase output is issued asynchronously to the A- and B-phases at a constant pulse width of
100µs.
Enter parameters so that PA1_09 ≤ PA1_10. If PA1_09 > PA1_10, the division ratio is 1.
Setting range
0: Entered values at PA1_09 and _10 are enabled.
16 to 4194304 [pulses]: Number of command input
pulses per revolution is enabled.
1 to 67108864 (in increments of 1)
