User, 18 Oct 2026, asked about the StepperOnline A6-EC100L2A1-M17
(100 W EtherCAT kit).
- The motor fits: torque about 0.02 N m needed at the motor through a
1:6 belt (0.32 rated); the belt brings the load inertia (about 25 to
35 kg cm2, estimate; record 20.5) to about 28x the 0.03 kg cm2 rotor.
- Take the pulse/RS-485 twin A6-RS100L2A1-M17 (USD 108.78): its drive
outputs the encoder as divided A/B/Z pulses for the line-scans and
takes pulse/direction from the planned PLC. The EtherCAT drive has no
divided output (A6-EC manual, CN1: 5 DI, 3 DO) and needs an EtherCAT
master.
- inline-optical-qc.md: spindle servo paragraph, sensor table, BOM
group; BOM line 109 to 250 (was 300 to 700). Total USD 16,073 to
32,734, THB 0.53M to 1.08M.
