7.6.3 Pulse output gear ratio
The number of pulses output from the MBDV drive per motor revolution can be congured by
parameters P3-13 and P3-14.
x 65535
P3-13 Pulse output gear ratio - numerator
P3-14 Pulse output gear ratio - denominator
Number of output pulses per revolution =
Note: The number of output pulses per revolution refers to the frequency multiplied by 4 of the A/B
phase

Defaults Description
P3-13 ON
Pulse output gear ratio -
numerator
0 ~ 65535 10000
Sets the numerator of the pulse output
gear ratio
P3-14 OD
Pulse output gear ratio -
denominator
0 ~ 65535 65535
Sets the denominator of the pulse output
gear ratio
Note:
1). The numerator P3-13 must be less than the denominator P3-14
2). When P3-13 > P3-14, the number of pulses output per motor revolution (post quadrature) = P3-13
Example:
The following are dierent ways to attain a output pulse resolution of 1000 pulses per revolution of
the motor. Pulses per revolution are taken post quadrature.
1). If A/B is counted at the same time, and the frequency is multiplied by 4:
P3-13 = 1000
P3-14 = 65535 or P3-14 = 1
2). If A/B are counted at the same time, and only the rising edge or falling edge is counted
when counting
Then: P3-13 = 2000
P3-14 = 65535 or P3-14 = 1
3). If only the A -phase output is counted, and only the rising edge or falling edge is counted
when counting
Then: P3-13 = 4000
P3-14 = 65535 or P3-14 = 1
