This article provides the essential technical and safety information required to install the IDMsm multi-axis drive. Follow these steps to ensure safe operation and optimal performance of your motion control system.
1. Safety & Compliance
Before beginning the installation, review these critical safety protocols:
- Electric Shock Hazard: High voltage levels are present. Wait at least 5 minutes after powering down before touching any connectors to allow internal capacitors to discharge.
- Grounding: The chassis must be grounded using a low-impedance wire connected to the central star-point of the machine's electrical cabinet.
- Standards: The IDMsm complies with IEC 61800-3 (EMC), IEC 61800-5-1 (Electrical Safety), and IEC 61800-5-2 (Functional Safety/STO).
2. Technical Specifications
Understanding the physical and electrical limits of the drive is vital for cabinet design.
- Dimensions: 168 mm (L) x 158.1 mm (D) x 48.3 mm (H).
- Weight: 2 kg.
- Input Voltage (VP): Up to 48VDC or 100VDC (Check your specific model label).
- Control Power (V_AUX): 24VDC ± 10%.
- Peak Current: Up to 20A per axis.
3. Environmental & Cooling Requirements
The IDMsm is designed for high power density and requires specific thermal management.
- Operating Temperature (0°C to 40°C): Natural convection is sufficient.
- Operating Temperature (40°C to 50°C): Forced air cooling is MANDATORY.
- Airflow Requirement: 24 CFM.
- Direction: Air must flow from the power connections toward the communication connectors.
- Failure to provide 24 CFM airflow above 40°C will trigger a thermal protection fault.
4. Hardware Connections
The IDMsm uses high-density connectors to manage multiple axes.
J1: Power & Motor Interface
This connector handles the main drive supply (VP) and motor phase outputs. Ensure wire gauges are sized to handle the combined peak current of all active axes.
J11: Encoder & Feedback
A high-density connector providing primary feedback for all axes (up to 4 axes depending on the model). It supports:
- Incremental (AqB)
- SinCos
- Absolute Encoders (BiSS, SSI)
J2 & J3: EtherCAT Ports
Standard RJ45 ports for EtherCAT In/Out communication.
5. Safe Torque Off (STO) Wiring
The STO function is a hardware-level safety path that prevents the motor from generating torque.
- Dual-Channel Requirement: The IDMsm features two STO channels (STO1 and STO2).
- Enabling Motion: Both channels must be powered with 24VDC to allow the motor to enable.
- Safety State: Removing power from either channel will immediately put the drive into a Safe Torque Off state.
6. LED Status Indicators
Use the onboard LEDs for quick hardware diagnostics:
- PWR (Green): Control power (V_AUX) is present.
- ERR (Red): A drive fault or EtherCAT error is active.
- RUN (Green): Indicates EtherCAT state (Init, Pre-Op, Safe-Op, Op).
- L/A (Green Flashing): EtherCAT link activity.
