5. PARAMETERS
(2) Setting for use of AD75P
The AD75P also has the following electronic gear parameters. Normally, the servo amplifier side
electronic gear must also be set due to the restriction on the command pulse frequency (differential
500kpps, open collector 200kpps).
AP: Number of pulses per motor revolution
AL: Moving distance per motor revolution
AM: Unit scale factor

Note: 1. Command pulse frequency at rated speed
2. Assuming that AP=8192 and AL=8000, the command unit amount per motor revolution is 8000 pulses/rev, which
makes positioning data setting easier.
3. In the case where the ballscrew lead is 10mm.
