GS AC servo drive units
GSK’s GS range addresses AC servo and spindle applications. Its official page separates compatible motor power ranges and lists several three-phase supply variants, which must be matched to the selected drive.
- Motor ranges
- 0.5–30 kW PMSM servo; 1.5–45 kW asynchronous spindle motors
- Supply variants
- Three-phase 220 V, 380 V or 440 V
- Feedback
- Second position-feedback input is described
- Braking
