Interface & Communication Configuration

Power Terminals

Screw terminals for DC bus ± input, U/V/W three-phase motor power output, external dynamic braking resistor connection port.

Feedback Interface

Dedicated multi-core socket for motor resolver analog position feedback wiring.

Analog Command Interface

±10V differential analog speed/torque reference input from upper CNC/PLC; auxiliary analog monitor output for actual speed/load signal inspection.

Digital IO Terminals

24VDC discrete terminals: servo enable input, fault reset input, servo-ready dry-contact output, fault alarm relay output.

Onboard Calibration Interface

Front panel adjustable potentiometers for speed/current loop gain & offset manual tuning.

Core Functions

Dual closed-loop analog control (current + speed loop); outer position loop controlled by external controller via ±10V analog command

Hardware resolver signal demodulation for rotor position sampling, no digital encoder required

Full protection suite: overcurrent, overvoltage, undervoltage, overheat, resolver breakage, motor phase loss; hardware relay alarm output for all faults

V1.6 circuit optimizes anti-vibration performance, better adaptability for variable-inertia loads than DSC1.4 series

External braking resistor consumes regenerative energy during high-inertia load rapid deceleration

Application Scenarios

Spare replacement & axis refurbishment of vintage European imported CNC lathe/milling machine feed drives

Legacy printing, packaging, textile production line analog servo maintenance replacement

Old metal stamping & forming equipment single-axis positioning drive retrofit

Laboratory analog servo test bench assembly with 200VAC local power grid matching

Usage & Maintenance Instruction

Cut off cabinet main power, wait minimum 15min for internal high-voltage capacitor full discharge before disassembly or wiring modification

Half-yearly heat sink dust cleaning to avoid overheat protection shutdown caused by poor heat dissipation

Moderate potentiometer adjustment; excessive rotation triggers control loop oscillation or internal component burnout

Strict resolver wiring verification during motor swap to prevent abnormal rotation & drive overload damage

Confirm site auxiliary power is 200VAC before power-on; wrong input voltage damages internal control transformer permanently
