1 - Numerator of output pulse
p29032 1 to
2147000000
1 - Denominator of output pulse
Note
When yo
u use the PTO electronic gear function, for the absolute encoder, the electronic
gear is based on the resolution of 8192 ppr.
The range of electronic gear ratio is from 0.02 to 200.
The electronic gear ratio can be set at SERVO OFF
state only.
Note
PTO direction
For an application of fully closed
-loop position control using PTI and PTO, you can set the
PTO direction with parameter p29033.
Note
When using the PTO function, the drive will output some pulses before the motor servo on if
you executing
the following operations.
•
Default the drive with the BOP instruction.
•
Configure the motor ID on the drive.
Note
When you use the PTO electronic gear ratio function, zero mark will not be generated.
PTO zero mark
Make the servo motor rotate for more than one revolution before using PTO's zero mark for
referencing.

Fast pulse train input position control (Fast PTI)
Fast PTI control mode is an optimized PTI control mode. You can achieve a better dynamic
response performance by using it.
The control mode specific functions of Fast PTI control mode are mostly the same as that of
PTI control mode. For detailed function descriptions, you can refer to Section "Pulse train
input position control (PTI) (Page 222)" for reference.
