αSTEP/Stepper Motor: When Using at an Altitude of More Than 1,000 m Above Sea Level
As the altitude gets higher, the heat radiation effect in the atmosphere decreases, thus, requiring measures such as lowering the ambient temperature of the product.
Below are the conditions for use when exceeding an altitude of 1000 m up to 2000 m.
Applicable Products
- AZ Series
- AR Series
- RKII Series
- CRK Series
- PKP Series (Motor-only product)
- PK Series (Motor-only product)
- CVD Series (Driver-only product)
Motor Operating Conditions
If using the motor at altitudes exceeding 1000 m but not exceeding 2000 m, ensure that the surface temperature of the motor case does not exceed the following values.
| Applicable Products | Motor Surface Temperature |
|---|---|
| AZ Series | 80 °C *1 |
| AR Series | 100 °C *1 |
| RKII Series | 100 °C *1 (85 °C *2) |
| Applicable Products | Motor Surface Temperature |
|---|---|
| CRK Series | 100 °C (85 °C *2) |
| PKP Series | 100 °C (85 °C *2) |
| PK Series | 100 °C (excluding models with encoders) |
- *1
- When obtaining UL Standards, as the thermal class of the motor part is Class A, do not exceed 75 °C.
- *2
- The brackets ( ) indicate values for the type with encoder.
Driver Operating Conditions
If the driver is to be used at an altitude of 1000 m above sea level and no higher than 2000 m, reduce the ambient temperature as follows.
For example, if a product with a maximum ambient temperature limit of 40 °C is used at an altitude of 2000 m, the maximum ambient temperature limit becomes 32 °C.
When Using a Geared Motor
Please use it at altitudes exceeding 1000 m but not exceeding 2000 m.
As altitude increases, there is a possibility of decreased life of oil seals and grease leakage within the gearhead due to temperature rise caused by differences in atmospheric pressure and reduced heat radiation effects.
If grease leakage is a concern, regularly check for grease seepage and consider installing oil catchers or similar devices on the equipment.
