Environmental, Transportation, and Storage Standards

1. Environmental parameters

Operating temperature: 0 ℃~+40 ℃; When the altitude is greater than 1000m and the environment is greater than 40 ℃, power reduction is required for use.

Transportation/storage temperature: -25 ℃~+70 ℃; Humidity 5%~95%, no condensation.

Environmental level: 2K3 (climate), 1C2 (chemical), 1B2 (biological), resistant to conventional corrosion and dust.

2. Transportation requirements

Use original factory packaging throughout the entire process, avoid severe impact or falling, and avoid impacting the motor shaft and encoder.

Lifting specifications:

AM8x1~AM8x5: can be directly transported;

AM8x6: Use slings to secure only the casing and prohibit hanging shafts;

AM807: The body comes standard with lifting lugs, and only lifting lugs are used to ensure force balance.

Stacking restrictions: There is a clear upper limit for the stacking height of different series of cardboard boxes, and large motors are only allowed to be placed in a single layer.

3. Long term storage

The longest storage period is 2 years, and exceeding this period will cause the lubricating grease to fail.

Conduct routine inspections every 6 months to maintain a dry, vibration free, and sun free environment.

The yellow protective cap on the shaft end must not be removed in advance to prevent damage to the shaft surface and bearings.

Core electrical and mechanical parameters

1. Temperature protection system

Built in LPTC-600 thermal sensor, temperature threshold:

Warning temperature: 120 ℃;

Shutdown protection temperature: 140 ℃;

The manual provides a full temperature range sensor resistance comparison table, which can be used for driver parameter configuration.

2. Power Capacity Reduction Rules

High temperature derating: Reduce the rated torque/current according to the temperature coefficient at an ambient temperature of 40-50 ℃.

Capacity reduction at altitude: Capacity reduction begins at altitudes greater than 1000m, with a 6% reduction at 2000m, a 17% reduction at 3000m, and a 55% reduction at 500m.

When high temperature and high altitude are superimposed, multiply the two coefficients to calculate the actual output.

3. Bearings and shaft loads

The front and rear bearings adopt sealed ball bearings, distinguishing between fixed and floating ends, and each series of bearing models is clear.

Strictly limit the radial and axial loads on the shaft, and use official load calculation tools to verify the service life for synchronous belt/gearbox applications.

Shaft end structure: Compliant with DIN 748 and DIN 6885 standards, supporting seamless couplings such as expansion sleeves and corrugated pipes.

4. Brake parameters (24VDC)

Power supply range: 24VDC (-10%~+6%);

Different specifications of motors have different brake torque, suction/release delay, and working current;

A single emergency stop has speed and inertia limitations, and frequent emergency stops can accelerate brake wear.

Mechanical installation and disassembly

1. Installation posture and heat dissipation

Standard posture IM B5, supports IM V1/IM V3; IM V3 is prone to fluid accumulation, and should be used with caution in high humidity/water dripping environments.

Reserve ventilation space and prohibit blocking the heat dissipation area; The installation of fan versions requires ensuring smooth air ducts.

2. Flange installation

The flange screws are made of 8.8 grade high-strength bolts, and the corresponding screw specifications and tightening torques for each series are clear and must be strictly followed.

Installation requirements:

Couplings/pulleys must be installed in the center and must not be loaded unevenly, otherwise it may cause vibration and bearing damage;

Hot installed components require temperature control operation and ensure coaxiality after installation.

Disassembly of shaft end accessories: Only use a dedicated puller and do not strike the shaft body.

3. Installation of external fan

The fan is powered by 24VDC, with power and current differentiated by specifications, and comes with dedicated cables.

Accurate installation alignment, compliant screw torque, and regular cleaning of the fan dust screen.

4. General mechanical taboos

Prohibit the shaft from bearing additional forced support to avoid over positioning of the shaft system;

Do not touch rotating parts or high-temperature shells during operation;

The overall vibration and impact of the machine must meet the standards, and exceeding the range may damage the encoder and bearings.

Distinguish between power lines, encoder lines, brake lines, and temperature detection lines, and the manual provides complete definitions for each pin.

2. Cable selection

Pre fabricated shielded cables from the original factory must be used. Non standard cables can easily cause EMC interference, communication failures, and loss of warranty.

Select the corresponding cable model based on the drive model (AX5000/AX8000), motor series, and usage scenario (fixed/high dynamic/torsional working conditions), including main line, extension line, and feedback line.

Service life of the connector: ≤ 500 insertions and removals, ≤ 10 rotations of the junction box. It is recommended to replace it if it exceeds the deadline.

3. Wiring specifications

Strictly distinguish between U/V/W three-phase power lines, PE grounding, positive and negative brake, temperature signal, and encoder signal lines.

Grounding requirements: The casing and cable shielding layer should be reliably grounded to meet EMC and anti electric shock requirements.

Sealing requirements: The sealing ring of the junction box should be intact, and the waterproof and dustproof structure should not be damaged.
