Core Functions

Full analog three-loop control (torque → speed → position external loop via upper controller analog command) for Indramat resolver-type servo motors

Real-time resolver position sampling to realize closed-loop speed regulation without digital encoder

Built-in overcurrent, overvoltage, overheat, motor phase loss and resolver disconnection fault protection with contact alarm output

Adjustable proportional/integral gain via panel potentiometer to adapt different motor inertia and load characteristics

External regenerative braking resistor connection for energy consumption during motor deceleration and rapid stop

Application Scenarios

Vintage CNC lathe/milling machine feed axis retrofitting & original equipment maintenance

Traditional printing machinery fixed-speed precision transmission servo control

Old-generation packaging automation equipment single-axis positioning drive

Metal forming auxiliary positioning servo system for aging production line spare replacement

European imported legacy textile machinery servo renovation

Usage & Maintenance Instruction

Cut off main power and wait minimum 15min for internal bus capacitor complete discharge before module disassembly

Regularly wipe surface heat sink dust every half year to avoid heat accumulation triggering overheat protection

Modify gain potentiometer gently; excessive rotation will cause loop oscillation or component burnout

Verify resolver wiring sequence strictly during motor replacement to prevent reverse rotation and drive overload damage

Check internal auxiliary fuse periodically if frequent power-on failure occurs
