Core Functions

Full closed-loop position/speed/torque triple regulation; supports analog speed control, pulse position control, digital input triggered multi-step fixed positioning. Integrated STO safe torque off function, complete protection including overcurrent, DC bus over/undervoltage, module overheat, encoder disconnection, front panel LED fault indication. No built-in electronic cam function compared to FM firmware variant.

Application Fields

Heavy-load CNC main spindle & heavy feed axes, large rotary printing press, high-power winding/unwinding machinery, extruder drive, heavy-duty automated forging & assembly production line.

Operation & Maintenance Instructions

Model 7 only matches 3-phase 380~480V AC input; single-phase 220V power supply triggers persistent DC bus undervoltage alarm and insufficient output torque.

Natural cooling design must strictly retain 50mm upper and lower cabinet clearance, avoid closed confined installation leading to overheat protection shutdown.

High frequent positive/negative reciprocating load must configure external high-power braking resistor to prevent internal brake overload damage.

Parameter upload/download requires matching corresponding DriveTop software version; parameters cannot be directly copied to FM firmware servo drives.
