ASDA-M Chapter 6 Control Mode of Operation
Revision December, 2014
6-13
Settings:
If the setting is wrong, the servo motor will easily have sudden
unintended acceleration.
Please follow the rules for setting:
The setting of pulse input:
Range of command pulse input : 1/50<Nx/M<25600
NOTE
1) The setting value cannot be changed when Servo ON neither
in PT nor in PR mode.
Electronic gear provides simple ratio change of travel distance. The high electronic gear
ratio would cause the position command to be the stepped command. S-curve or
low-pass filter can be used to improve the situation. When electronic gear ratio is set to 1,
the motor will turn one cycle for every 1280000PUU. When electronic gear ratio is
changed to 0.5, then every two pulses from the command will be refer to one PUU of
motor encoder.
For example: after setting the electronic gear ratio properly, the moving distance of the
object is 1μm/pulse, which is easier to use.
