Drives & Motors
OD700 – OPENdrive

OD700 OPENdrive are equipped with EtherCAT fieldbus, have compact mechanical dimensions and support a wide range of operating currents and power supply voltages. These drives are the perfect solution for machines dedicated to wood and marble working, sheet metal cutting (plasma, Oxy-fuel, Water-jet, Laser cutting) and for milling machines.
There are six available sizes, in four different mechanical formats, having nominal currents of 3A, 4,5A, 6A, 12A, 18A and 36A. All models offer the integrated security function STO (Safe Torque Off) to control the cut out of the power supplied by the drive to the motors allowing the safe intervention of the operator without removing the power to the machine tool.

YASKAWA Sigma-5 SD

The Sigma-5 SD combined spindle & servo system is proposed for motion applications demanding high dynamic and accuracy, fast positioning and perfect multi-axis synchronization.

Performances:

  • Speed Loop Bandwidth of 1.6 kHz
  • Shortened settling time, reduced positioning time, higher throughput
  • Improved machine reliability, reduced service and maintenance costs, less standstill time
  • Excellent anti-vibration control: simpler mechanics with less weight, higher machine production, less energy consumption
  • Overload 350% for 3-5 sec.
  • High peak torque, fast acceleration, no amplifier oversizing
  • Regenerative power converter completely returns braking energy back to the mains supply
  • Advanced Auto-tuning, One Parameter Tuning
OS3 Servomotors

The OS3 motors are high voltage sinusoidal brushless motors with high-inertia. They can also have an optional holding brake and include a thermal sensor.
The position feedback is a resolver and all motors have an IP65 protection level. The available standstill torques range from 0.2Nm up to 66Nm, with maximum speed of 3000, 4000 and 6000 rpm. The motors can support high acceleration and deceleration up to 110,000rad/sec².
