Motor specs at a glance
The GYS401DC2-T2C is a 0.4 kW low-inertia servo motor from the GYS series, rated for 3000 r/min continuous speed. The 17-bit incremental encoder (T option) gives position feedback resolution fine enough for most pick-and-place, indexing, and light machining axes — 131,072 counts per revolution means the drive sees position changes down to roughly 0.003° per count. Input voltage is the AC 200 V class, so it pairs with standard 200 V-class servo drives common in Asian and 230 V single/three-phase markets. Flange mounting (C option) bolts directly to the machine frame or gearbox adapter plate.
The 0.4 kW rated output (400 W) is the continuous mechanical power at rated speed — enough for a small conveyor index, a 1-axis pick head, or a light rotary table. The low-inertia rotor (GYS basic type) means the motor accelerates and decelerates quickly, which is the deciding factor when cycle time matters more than peak torque. The 17-bit incremental encoder gives position feedback without absolute multi-turn data. If the application needs to know the axis position immediately after power-up without a homing move, you would need an absolute encoder variant instead. For most incremental servo loops, 17 bits is sufficient resolution for smooth velocity control and repeatable positioning within a few encoder counts.
