ISM Equipment We Repair — By Category
ISM Product Lines We Repair
Our engineers are trained on the full ISM product range. Below are the major product families we service.
ACP (Automation Control Platform)
ISM's modular automation control backbone featuring real-time kernel, multi-axis synchronization, and integrated safety functions. Common faults include CAN communication timeouts, motion profile corruption, and safety relay module failures in high-cycle production environments.
Compact Servo Drives
Single and multi-axis servo amplifiers for stepper and brushless motors with encoder feedback. Typical issues: encoder connection degradation, capacitor aging under thermal stress, and firmware revision conflicts during updates.
Motion Controllers - Distributed I/O
Decentralized control nodes for pulse generation, position feedback, and real-time I/O switching. Common failures: terminal block corrosion in humid textile mills, relay contact welding, and CAN transceiver damage from electrical transients.
ISM Encoder Interfaces & Feedback Modules
High-resolution absolute and incremental encoder signal conditioning with SSI, CANopen, and analog outputs. Repair focuses on signal processing circuit failures, optical coupler degradation, and multi-turn absolute encoder battery replacement.
Safety Control Modules (SCM)
Integrated safety relay and logic functions for machinery guarding and E-stop circuits compliant with ISO 13849-1 Category 3. Failures include safety contact resistance drift, diagnostic output faults, and firmware validation errors during certification.

Common ISM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ISM equipment arriving at our workshop.
- ✓CAN Bus Communication Timeout Errors — ISM drives communicate via CAN fieldbus in networked systems. Intermittent timeouts occur due to corroded CAN connectors (common in textile mills with moisture ingress), damaged termination resistors, or firmware version mismatches across nodes in multi-drive systems.
- ✓Servo Drive Capacitor Failures and Thermal Shutdown — Electrolytic capacitors in ISM servo drive power stages degrade under sustained high-temperature operation common in Indian automotive pressing and injection molding plants. Aging capacitors increase ESR (equivalent series resistance), triggering thermal shutdown routines and preventing motor acceleration.
- ✓Encoder Signal Loss and Position Feedback Faults — Incremental and absolute encoders connected to ISM motion controllers experience intermittent signal loss due to cable flex-fatigue near servo connectors (especially in automated transfer lines), corrosion in multiconductor encoder cables, or internal encoder optical/magnetic sensor degradation.
- ✓Pulse Train Generation Errors and Missed Steps — ISM compact servo drives fail to generate clean pulse trains for stepper motor control when output stage transistors degrade, PWM frequency generation circuits develop timing jitter, or the motion profile memory becomes corrupted from incomplete flash updates.
- ✓Safety Relay Module Diagnostic Output Failures — ISM Safety Control Modules (SCM) lose diagnostic capability when contact resistance in dual-channel safety switches exceeds ISO 13849-1 thresholds, or microcontroller firmware that monitors relay health becomes corrupted due to power loss during software updates.
- ✓CAN Transceiver and Fieldbus Interface Damage — Electrical transients from motor contactor switching or incoming power surges damage ISM CAN transceiver chips and optical isolation circuits, particularly in plants with inadequate surge suppression. Damaged transceivers prevent any fieldbus communication and require board-level replacement.

Frequently Asked Questions — ISM Repairs
Do you repair ISM equipment anywhere in India?+
Yes. Synchronics repairs the full ISM product range — servo drives, motion controllers, encoder interfaces, and safety control modules. We offer PAN-India pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All repairs are processed at our factory-equipped facility in Vadodara, Gujarat, and returned within 5-7 working days.
What makes Synchronics the right partner for ISM servo drive repair?+
Our engineers hold factory training from ISM GmbH and maintain comprehensive test benches for servo amplifier diagnostics including CAN protocol validation, encoder signal analysis, and thermal performance verification. We keep ISM-approved capacitors, power transistors, and CAN transceivers in stock. Every repaired ISM drive is run through closed-loop position feedback tests and load simulation before shipment — far beyond basic bench testing.
Our ISM ACP motion controller shows CAN timeout errors. Can you fix it?+
CAN communication faults are one of the most common ISM repairs we handle in Indian manufacturing plants. We isolate the root cause — whether connector corrosion, failed termination resistors, firmware mismatches, or damaged CAN transceiver chips — through systematic network diagnostics. Most CAN faults are resolved within 48 hours. Bring in your ISM ACP node and any connected devices (servo drives, encoder interfaces) for comprehensive network validation.
How do you certify ISM safety module repairs for ISO 13849-1 compliance?+
ISM Safety Control Modules undergo contact resistance measurement, relay functional testing, and diagnostic firmware validation using our certified testing procedures. We perform dual-channel safety chain testing per ISO 13849-1 Category 3 and issue a repair certificate documenting pass/fail results and contact resistance baseline data. This documentation supports your machinery safety validation and inspector audits.
Can you handle ISM firmware updates and multi-drive synchronization issues?+
Yes. We flash ISM firmware from verified factory image files and validate firmware consistency across all nodes in multi-axis systems using CAN protocol analyzers. Synchronization faults caused by firmware version mismatches or corrupted motion profiles are corrected through controlled re-flashing and closed-loop position verification testing. This service is essential for textile mills and packaging lines running synchronized multi-drive systems.
How do I send my ISM unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ISM drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on ISM repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your ISM unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
