APS Product Lines We Repair
Our engineers are trained on the full APS product range. Below are the major product families we service.
APS Brushless Servo Drives
Three-phase brushless DC motor amplifiers with integrated motion profiling and real-time feedback control. Common issues include Hall sensor failures, phase commutation faults, and thermal shutdown triggers in high-speed spindle and transfer line applications.
APS Stepper Motor Controllers
Microstepping drivers for NEMA and closed-loop stepper systems with step/direction interface. Repair needs focus on power stage transistor failures, encoder signal loss, and firmware corruption in precision positioning equipment.
APS Motion Control Modules
Standalone and networked motion controllers with EtherCAT and MODBUS support for multi-axis coordination. Issues include communication timeouts, trajectory generation faults, and power supply regulation problems affecting servo loop stability.
APS Analog Servo Amplifiers
Legacy voltage-input servo amplifiers for legacy textile and printing machinery. Common faults: capacitor degradation, potentiometer wear, offset drift, and output stage saturation causing jerky motion.
APS Encoder and Feedback Modules
Signal conditioning cards and quadrature converters for resolvers, encoders, and tachometers. Frequent repairs include optical coupler burnout, differential signal corruption, and ADC linearity drift affecting closed-loop accuracy.

Common APS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in APS equipment arriving at our workshop.
- ✓Hall Sensor Commutation Loss and Phase Mismatch — APS brushless drives rely on three Hall sensors for commutation timing. Sensor degradation, wiring corrosion in humid environments, or PCB trace cracking causes incorrect phase detection, leading to cogging, loss of torque, and emergency shutdown codes ERR-11 or ERR-12.
- ✓Thermal Runaway and Shutdown Protection Faults — APS drives monitor MOSFET and output stage temperature via NTC thermistors. Thermistor aging, heatsink fouling from dust, or loss of cooling fan airflow triggers spurious thermal faults (ERR-08, ERR-09), forcing the drive offline even at moderate load.
- ✓Encoder Signal Loss and Quadrature Decoding Error — APS closed-loop servo systems require stable encoder feedback. Cable shielding failure, connector corrosion, or quadrature counter overflow causes position tracking errors, servo following faults (ERR-05), and loss of position hold during idle periods in textile looms and CNC machines.
- ✓Power Stage MOSFET or IGBT Failure and Short Circuit — APS servo drives use high-current power transistors in half-bridge and bridge configurations. Gate drive circuit aging, transient voltage spikes from motor winding inductance, or solder joint cracks cause MOSFET short or open faults, resulting in shoot-through current and thermal cascade.
- ✓Firmware Corruption and Flash Memory Checksum Error — Firmware corruption in APS motion controllers occurs after brownout events, failed updates, or long-term EEPROM wear. Checksum errors block drive initialization with ERR-20 or ERR-21, preventing any motion control operation in packaging lines and transfer systems.
- ✓Capacitor Degradation and Power Supply Ripple — Electrolytic capacitors in APS power supplies degrade over 5-10 years, especially in high-ambient-temperature plants. ESR increases and capacitance drops, causing excessive bus voltage ripple, servo loop instability, and random amplitude modulation of motor current.

We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Nagpur, and all metro cities. Single repair facility in Vadodara, Gujarat with 180+ engineers and 30 years of industrial electronics expertise.
What is the typical turnaround time for APS servo drive repair?+
Standard APS servo drive repairs take 5-7 working days from receipt in Vadodara. Diagnostic testing, component replacement, firmware verification, and burn-in testing are included. Emergency rush repairs can be completed in 48-72 hours for critical production shutdowns. We provide daily status updates via email and phone.
Can Synchronics repair legacy APS analog servo amplifiers used in old textile looms?+
Absolutely. Synchronics routinely repairs vintage APS ASA-15, ASA-30, and ASA-60 analog amplifiers still running in Indian textile plants. We stock hard-to-find vintage capacitors, potentiometers, and power transistors. We also perform schematic-level troubleshooting for units no longer in APS technical documentation, and provide multi-year warranty on refurbished legacy drives.
Do you provide firmware updates and programming for APS motion controllers?+
Yes. Synchronics holds APS factory programming credentials and updates firmware on all MCM and SMC controller series. We reprogram flash memory after hardware repair, customize motion profiles for your application if needed, and test EtherCAT or MODBUS communication post-update. All firmware carries checksum verification to prevent future corruption.
What warranty do you offer on repaired APS equipment?+
