Command Interface：±10V analog speed/torque signal, pulse+direction position command

Debug & Fieldbus：Front X1 RS232 for DriveTop parameter setup; Profibus-DP / CANopen / SERCOS via plug-in option board

Core Functions

Full closed-loop position/speed/torque triple regulation; three running modes: analog speed control, pulse positioning, multi-step fixed positioning triggered by digital input. Integrated STO safe torque off, full protection against overcurrent, bus over/undervoltage, IGBT overheat, encoder fault; front LED fault code indication. Lacks master-slave sync and electronic cam compared with FM version drive.

Application Fields

Medium-load CNC feed axes, mid-sized rotary printing machines, medium winding/slitting equipment, automatic packaging & assembling lines.

Operation & Maintenance Instructions

Type7 only connects 3-phase 380~480V AC; single-phase 220V input leads to persistent DC bus undervoltage alarm and insufficient output torque.

Passive cooling design must retain specified cabinet clearance; closed confined installation causes frequent overheat shutdown.

High cyclic forward/reverse working condition needs external high-power braking resistor to avoid internal brake burnout.

Parameter upload/download requires matched DriveTop software version; parameters cannot be copied cross FW/FM firmware directly.
