Installation Precautions for REXROTH-MSK050C-2-1-1024×738 Servo Motor

1. Pre-Installation Preparation & Environmental Requirements

Environmental Assessment: Install the motor in a clean, dry environment with a temperature range of 0°C to 40°C (non-condensing) and relative humidity ≤ 90% (without direct moisture or water splash). Avoid areas exposed to corrosive gases, dust, oil mist, or strong electromagnetic interference (e.g., proximity to high-voltage cables or welding equipment).

Load & Compatibility Check: Confirm that the motor’s rated torque, speed, and power match the mechanical load requirements (refer to the product datasheet for specifications). Verify compatibility with the connected drive system (e.g., REXROTH servo drives) to prevent mismatched operation.

Tool & Material Readiness: Use torque wrenches, precision alignment tools (e.g., laser aligners or dial indicators), and appropriate fasteners (compliant with the motor’s mounting hole specifications) to avoid damage during installation.

2. Mechanical Installation Guidelines

Mounting Surface Preparation: Ensure the motor’s mounting flange (and the mating surface of the driven equipment, e.g., gearbox or load) is flat, clean, and free of burrs, rust, or debris. Use a surface gauge to check flatness—deviations must not exceed 0.1 mm per 100 mm to prevent uneven stress on the motor housing.

Shaft Alignment: Achieve precise coaxial alignment between the motor shaft and the driven shaft (e.g., coupling or pulley connection). Misalignment (radial: ≤ 0.1 mm; angular: ≤ 0.1°) can cause excessive vibration, bearing wear, or shaft damage. For flexible couplings, follow the coupling manufacturer’s alignment tolerances; for rigid couplings, stricter alignment is required.

Fastener Torque Control: Tighten the mounting flange bolts to the specified torque value (refer to the product manual—typically 8–12 N·m for M6 bolts, depending on material) using a calibrated torque wrench. Over-tightening may deform the flange; under-tightening can lead to loosening during operation.

Shaft Load Limitations: Do not apply axial or radial loads exceeding the motor’s rated limits (axial load: ≤ 500 N; radial load: ≤ 800 N at the shaft end) during installation. Avoid striking the shaft with hard tools (e.g., hammers) to prevent damage to the encoder or bearing assembly.

3. Electrical Connection Precautions

Power Disconnection: Before wiring, ensure the main power supply to the servo drive (and associated control systems) is completely disconnected and locked out/tagged out (LOTO) to prevent electric shock.

Wiring Compliance:

Use cables with insulation ratings matching the motor’s voltage class (e.g., 600 V AC for power cables) and cross-sectional area (refer to the datasheet—typically 1.5–2.5 mm² for power lines, 0.5–0.75 mm² for encoder signals).

Separate power cables (motor phase wires, ground wires) from signal cables (encoder, feedback wires) by at least 100 mm to avoid electromagnetic interference (EMI) affecting feedback accuracy. Use shielded cables for encoder signals, and ground the shield at one end (preferably the drive side) to reduce noise.

Grounding Requirements: Connect the motor’s frame ground terminal (marked “PE”) to a dedicated protective earth (PE) conductor with a cross-sectional area ≥ 2.5 mm². Ensure the ground resistance is ≤ 4 Ω to prevent electric shock and ensure proper fault protection.

Encoder Connection: Handle the encoder (1024-line resolution, as indicated by “1024×738”) with extreme care—avoid bending or pulling the encoder cable (minimum bend radius: ≥ 10× the cable diameter). Verify pin-to-pin wiring against the motor and drive manual to prevent reverse polarity or incorrect signal mapping, which can cause position feedback errors.
