APPENDICES
(2) Parameter setting
To connect AlphaStep/5-phase, set the following in the system setting of
MT Developer2.
• Set "SSCNET
/H" for communication type in SSCNET setting.
• Set the amplifier model in amplifier setting to "αSTEP/5-Phase (ORIENTAL
MOTOR)".
(3) Control of AlphaStep/5-phase parameters
Parameters set in AlphaStep/5-phase are not controlled by Motion CPU.
They are set directly using AlphaStep/5-phase data editing software. For details
on setting items for AlphaStep/5-phase, refer to the instruction manual of the
AlphaStep/5-phase.
