Core Functions

01VRS universal firmware integrates full position/speed/torque closed-loop control; three selectable operation modes: analog voltage speed control, pulse-based position control, digital-input triggered 32-segment internal automatic positioning program. Equipped with soft/hard travel limit, auto homing and brake delay logic; complete protection against overcurrent, DC bus over/undervoltage, power module overheat and encoder cable break with front LED fault code indication.

Application Fields

Food packaging feeding axes, precision rotary indexing tables, electronic component assembling machines, winding & cutting equipment, automatic labeling die-cutting and belt conveyor automation systems.

Operation & Maintenance Instructions

This Type-3 low voltage model is strictly restricted to AC200~240V input; connection to 380V mains will permanently damage internal power stage.

Replacement requires same 01VRS firmware variant; parameters cannot be directly copied from V24 firmware drives.

Install external high-power braking resistor for frequent forward-reverse cyclic operation to avoid built-in brake overheating failure.

Parameter commissioning needs matched DriveTop software version compatible with VRS firmware revision.
