Applications

24 = 24VDC(for 100/200/400W)
48 = 48VDC(for 400/750/1000W)
220 = 220VAC(for 100/400/750/1000W, 1800/3800W available on request)
380 = 380VAC(for 1800/3800W)
*For servo motors operated in a vacuum pressure range of 10-10000 Pa, we recommend utilizing a low-voltage (24 or 48 VDC) winding motor to eliminate the risk of breakdown.
100 = 100W
200 = 200W
400 = 400W
750 = 750W
1000 = 1KW
1800 = 1.8KW
3800 = 3.8KW
Blank = resolver. Incremental feedback
To achieve accurate positioning, it is necessary to implement a homing process , as the motor position is not recorded during power-off.
AE = geared multi-turn absolute encoder
With 17-bit single-turn resolution and 12-bit multi-turn. During power-off, the motor position is recorded. No back-up battery is required.
