Digitax HD M750 / M751 / M753 — compact servo drives 0.25–7.5 kW, 1.5–16 A, 300 % overload
Country: Poland · Model: Digitax HD M750 / M751 / M753
Digitax HD are compact servo drives for 0.25–7.5 kW and currents of 1.5–16 A with 300 % overload for 3 s. The M750 with Ethernet, the basic M751 with Modbus RTU and the M753 with EtherCAT are installed on single- and multi-axis machines with pulsed loads, where high peak torque is needed for fast acceleration.

Description
According to the brochure the range is 0.25–7.5 kW, and on the supplier page 0.37–5.5 kW; the motors matched to the drive develop 0.7–51 N·m. Supply is 1×230, 3×230 or 3×400 V ±10 %, output frequency 0–550 Hz, up to 3 000 Hz on request, protection rating IP20. The drive runs servo motors in closed loop, permanent-magnet synchronous motors (RFC-S), induction motors in open loop and in RFC-A, and also returns energy to the mains (Regen). It already includes a class A EMC filter, a braking transistor, a PID controller, two STO inputs, a PLC in CODESYS and the AMC motion controller. The two slots accept PROFINET, PROFIBUS, DeviceNet, CANopen, SI-Ethernet, EtherCAT, SI-I/O and encoder modules, the SI-Safety safety module per IEC 61800-5-2, and the MCi200 and MCi210 processor modules.
How to choose
The model is chosen by interface. The M750 has Ethernet, the M751 is basic with Modbus RTU, and the M753 works with EtherCAT. Power up to 7.5 kW and torque up to 51 N·m suit compact axes. For continuous duty with sustained torque the manufacturer recommends the Unidrive M700 with Unimotor FM motors, and for induction motors without servo mode there is the Unidrive M600.

FAQ
How do M750, M751 and M753 differ?
The M750 has an Ethernet interface, the M751 is basic and works with Modbus RTU, and the M753 connects over EtherCAT.
Which motors match Digitax HD and what torque do they have?
The servo motors matched to the drive develop torque from 0.7 to 51 N·m.
What is the overload capacity of Digitax HD?
300 % of rated current for 3 s, at currents of 1.5–16 A.
What is the output frequency of the drive?
0–550 Hz, and up to 3 000 Hz on request.
Does Digitax HD have safe torque off?
Yes, two STO inputs, and the SI-Safety module extends the functions per IEC 61800-5-2.
