ERSEM Product Lines We Repair
Our engineers are trained on the full ERSEM product range. Below are the major product families we service.
ERSEM EasyDrive Series
Compact AC drives for small to medium motors (0.75-5.5 kW). Common faults include firmware corruption, capacitor degradation in humid environments, and display panel failures. These drives are popular in Indian textile mills and small manufacturing units for basic speed control and soft-start applications.
ERSEM PowerControl Frequency Converters
Heavy-duty variable frequency drives rated 7.5-55 kW for industrial motors. Known for durability but prone to thermal stress failures in tropical Indian climates. Common issues include IGBT module burnout, control board faults under load shedding, and communication protocol errors in networked installations.
ERSEM SoftStart Controllers
Thyristor-based soft starters (11-90 kW) for high-inrush current motor applications in pumps and compressors. Prone to thyristor triggering failures, gate driver circuit degradation, and control input signal loss in noisy factory environments common to Indian steel and cement plants.
ERSEM ProMotion Servo Drive Systems
Closed-loop servo motion controllers for precision positioning in packaging, textile dyeing, and machine tool applications. Complex faults include encoder interface failures, analog feedback signal drift, and parameter corruption. Require specialized diagnostic equipment and software access to repair effectively.
ERSEM PLC-Logic Automation Modules
Compact programmable logic controllers with I/O expansion for process automation and sequencing. Subject to memory degradation, real-time clock failures, and digital input/output module faults when exposed to moisture and electrical noise typical in Indian food processing and pharmaceutical facilities.
ERSEM HMI Touch Panel Series
7-15 inch human-machine interface panels with resistive touch screens for plant operator control. Common failures include touch screen calibration loss, LCD backlight aging, internal power supply failures, and data logger memory corruption in extended storage conditions.

Common ERSEM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ERSEM equipment arriving at our workshop.
- ✓IGBT module thermal burnout and gate driver failure — ERSEM PowerControl drives operate in high-ambient Indian industrial environments (40-50°C). Inadequate cooling fin cleaning, thermal compound degradation, and gate driver IC solder joint fatigue lead to sudden module failure and complete loss of motor control.
- ✓Capacitor electrolyte leakage and voltage regulation loss — ERSEM EasyDrive and SoftStart units use aluminum electrolytic capacitors sensitive to humidity and vibration. Indian coastal facilities and monsoon exposure accelerate electrolyte loss, causing ripple voltage rise, false fault codes, and eventual component burnout.
- ✓Encoder signal loss and servo feedback failure — ERSEM ProMotion servo systems experience encoder connector corrosion, shielding degradation, and cable continuity loss in wet processing environments. Intermittent position feedback causes hunting, oscillation, and safety alarm trips.
- ✓PLC memory corruption and loss of ladder logic program — ERSEM PLCLogic modules experience memory errors from power transients, electrostatic discharge in dry Indian climates, and corrupted backup batteries. Plant restarts trigger fault code 0x2401 and loss of automation sequence.
- ✓Thyristor gate trigger circuit malfunction in soft starters — ERSEM SoftStart controllers experience gate driver IC failures and trigger pulse transformer saturation from repetitive load switching stress. Affects textile mills and paper mills with 100+ daily start-stop cycles, causing incomplete motor acceleration and electrical stress.
- ✓HMI touch screen unresponsiveness and data loss — ERSEM TouchPanel units suffer resistive touch membrane wear, LCD display degradation from continuous operation, and internal SD card file system errors common in 24/7 process control environments across Indian pharmaceutical and food sectors.
