Core Functions

Standard FW firmware supports full position/speed/torque three closed-loop regulation; analog speed control, pulse position positioning, I/O sequential fixed-step program operation available. Full protection set including overcurrent, DC bus over/undervoltage, power module overheat, encoder breakage, STO safe torque off, front LED digital fault code indication; no native electronic cam & multi-axis electronic gearing vs FM dedicated firmware variant.

Application Fields

Heavy-duty CNC machine spindle/feed drive, large roll slitting & winding machinery, rubber extrusion equipment, automotive heavy component press automation, large-format rotary printing equipment.

Operation & Maintenance Instructions

Type-7 high voltage model only for AC380~480V three-phase mains; 220V input triggers persistent DC bus undervoltage alarm and insufficient output torque.

Replacement must adopt identical FW firmware version; parameter files cannot be directly cloned from FM firmware drives.

High cyclic frequent forward-reverse working condition requires external high-power braking resistor to prevent internal bleeder overheat burnout.

Parameter commissioning needs matching DriveTop software edition corresponding to built-in FW firmware revision.
