Internal Product Review
The digifas 7202-CAN is a Kollmorgen servo amplifier designed for industrial motion control, with a 3-phase 400 VAC supply and 2.8 Arms rated output current. CAN integration through a SubD 9-pin socket and 1 kHz current loop bandwidth support stable, responsive axis performance. Strong dynamic capability at 5.6 Arms peak output current makes the unit a very capable choice for 1.7 kVA servo applications.

Product Description:
The digifas 7202-CAN servo amplifier is manufactured by Kollmorgen as part of the DIGIFAS 7000 Servo Amplifiers series. Designed for closed-loop control of brushless servo motors, the module converts line power, executes current regulation, and communicates with the motion controller over a CAN network. The fieldbus wiring is routed through a Sub-D 9-pin socket, which supports straightforward network integration in automated equipment. By combining power conversion and real-time communication, the unit helps coordinate axes in packaging machines, material-handling cells, and other industrial systems.
The power section is fed from a three-phase 400 VAC mains supply and charges an intermediate circuit that stabilizes at 560 VDC. Within this range, the amplifier can support a connected load of 1.7 kVA while delivering a rated motor phase current of 2.8 Arms and tolerating peak demands up to 5.6 Arms. Safe commutation is maintained when the motor inductance is at least 15 mH. A brake output rated for 1 A is provided for holding brakes, and the residual voltage drop of the output stage is limited to 5 V to reduce motor heating during low-speed operation. Under nominal conditions, the converter loses 45 W to internal dissipation, and that heat is removed by convection through its aluminum housing.
A continuous ballast resistor absorbs regenerated energy at 75 W, and an overvoltage trip threshold of 750 V protects the DC bus when excess braking power persists. The current loop responds up to 1 kHz, while the insulated-gate output stage is modulated at 8.33 kHz to smooth motor torque. Mechanical data include a footprint of 275 × 71 × 235 mm and a weight of 2.1 kg, allowing dense panel layouts. The compact housing supports installation in control cabinets where space is limited.
