DC motor-side output up to 80 V and 5 A in the listed repair configuration

Speed command response governed by analog input range, PID settings and motor inertia

Protection trip levels act according to detected overcurrent, overvoltage, overtemperature or ground fault

Material Composition:​

Enclosure: industrial metal/coated steel controller case

Internal boards: multilayer control PCB

Power stage: semiconductor modules with heat dissipating elements

Terminals: insulated screw/clamp blocks for power and control wiring

Structural Characteristics:​

VS controller body with main power terminals and control terminal block

Optional ZSP-13 board for current-to-voltage speed command interface

Separate power and signal connection areas

Nameplate CODE NO defining variant, rating and firmware

Working Principle:​

The controller receives AC input, converts and regulates DC/output power for the motor, and adjusts output according to the analog speed command. With ZSP-13, 4-20 mA field signal converts to 0-10 V command voltage. Control circuits monitor current, voltage and temperature, then modify output or trigger protection trips to prevent drive damage.

Installation Requirements:​

Verify CODE NO, rated input voltage, output power and motor specifications before installation

Install in a ventilated control cabinet with separated power and signal cable routing

Use shielded signal cable and proper earth grounding

Provide heat dissipation space according to output power and enclosure temperature

For RS485 communication, install terminating resistors and correct polarity

Usage Precautions:​

Perform no-load test before connecting full mechanical load

Confirm 4-20 mA support; if native current input is unavailable, install ZSP-13 or approved converter

Do not exceed nameplate voltage, current and power ratings

Inspect protection trips for overcurrent, overvoltage, overtemperature and ground fault during commissioning
