2. REPLACEMENT PROPOSAL FROM A-MOTION TO QDS-MOTION
2.2 Servo Amplifier Correspondence
The servo system network is changed from SSCNET to SSCNET III or SSCNET III/H. Use a servo
amplifier compatible with SSCNET III or SSCNET III/H. Select a servo motor that can be connected with an
SSCNET III or SSCNET III/H-compatible servo amplifier.
<Amplifier correspondence>
Use A17nSHCPUN/A173UHCPU
-->
Use Q17nDSCPU
