08
Number of output
pulses per
revolution 0: Entered values at PA1_09 and _10 are enabled.
16 to 262144 [pulses]: Number of command input
pulses per revolution is enabled.
2048 Power
Enter the number of pulses output per motor rotation from pulse output terminal (FFA, *FFA, FFB and
*FFB).
The setting range is 16 to 262144 [pulses]. However, if the end of the model of the servomotor is "HB2"
(18-bit encoder), the maximum value is 65536 [pulses]. (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

09
Numerator of electric gear for
output pulses

10
Denominator of electric gear for
output pulses
1 to 4194304 (in increments of 1) 16 Power
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.)
In case of an 18-bit encoder, specify "1/32" to output 2048 (65536 × 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
125µs.
Enter parameters so that PA1_09
≤ PA1_10. If PA1_09 > PA1_10, the division ratio is 1.
