Precautions for Correct Use

Disconnect all connections to the Servo Drive before attempting a megger test (insulation resistance measurement) on a Servo Drive. Not doing so may result in the Servo Drive failure.
Do not perform a dielectric strength test on the Servo Drive. Internal elements may be damaged.

*1. The values outside parentheses indicate the rated value, and the values inside parentheses indicate the range of
      acceptable variation.
*2. If the power supply is turned ON slowly, a Regeneration Circuit Error Detected during Power ON (Error No. 14.02) may
      occur. Check that the power supply has a capacity sufficiently greater than the total capacity of the Servo Drive and the
      peripheral devices.
*3. Select a DC power supply in consideration of the current values that are specified in the current consumption.
      The rated current value that is printed on the product nameplate is a condition to apply the 1S-series product for the
      UL/Low Voltage Directive.
      Therefore, you do not need to consider it when you select a DC power supply for each model.
*4. This is the maximum heating value in applicable Servomotors.
      Refer to the table on the page 14 for the Heating Values of Applicable Servomotors.
*5. This hold time at momentary power interruption is that of the main circuit. In order to maintain power supply to the
      control circuit at momentary power interruption, use a DC power supply, which meets the following conditions, for the
      control power supply:
      Reinforced insulation or double insulation, and the output hold time of 10 ms or more.

*1. This is a typical value for when the Servomotor is used at a normal temperature (20°C, 65%) in combination with a Servo Drive.
*2. The rated values are the values with which continuous operation is possible at an ambient temperature of 40°C when the Servomotor is horizontally installed on a specified radiator plate.
*3. The momentary maximum torque is approximately 300% of the rated torque, except for some models.
*4. The momentary maximum torque is approximately 350% of the rated torque. Output at the momentary maximum torque shortens detection time of the overload protection function. Refer to Electronic Thermal Function in the AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (Cat.No.I586) for details.
*5. This value is for models without options.
*6. The allowable radial and thrust loads are the values determined for a limit of 20,000 hours at normal operating temperatures.
The allowable radial loads are applied as shown in the following diagram.

*7. When the brake is released for a vertical axis, refer to the AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (Cat.No.I586) to set an appropriate value for Brake Interlock Output (4610 hex).
*8. This is a non-excitation brake. It is released when excitation voltage is applied.
*9. This value is a reference value.

*1. This is a typical value for when the Servomotor is used at a normal temperature (20°C, 65%) in combination with a Servo Drive.
*2. The rated values are the values with which continuous operation is possible at an ambient temperature of 40°C when the Servomotor is horizontally installed on a specified radiator plate.
*3. This value is for models without options.
*4. The allowable radial and thrust loads are the values determined for a limit of 20,000 hours at normal operating temperatures.
The allowable radial loads are applied as shown in the following diagram

*1. The value is the allowable continuous output torque of the Decelerator. Take care so that this value is not exceeded.
*2. The value is the maximum allowable torque of the Decelerator. Take care so that this value is not exceeded.
Note:
1. The Decelerator inertia is the Servomotor shaft conversion value.
2. The protective structure rating of the Servomotor with the Decelerator is IP44.
3. The Allowable radial load column shows the values obtained at the center of the shaft (T/2).

R88M-1[] / R88D-1SN[]-ECT Specifications 70

4. The standard shaft type is a straight shaft. A model with a key and tap is indicated with “J” at [] of the model number.
5. Take care so that the surface temperature of the Decelerator does not exceed 70°C.

*1. The value is the allowable continuous output torque of the Decelerator. Take care so that this value is not exceeded.
*2. The value is the maximum allowable torque of the Decelerator. Take care so that this value is not exceeded.
Note:
1. The Decelerator inertia is the Servomotor shaft conversion value.
2. The protective structure rating of the Servomotor with the Decelerator is IP44.
3. The Allowable radial load column shows the values obtained at the center of the shaft (T/2).

* The value is the maximum allowable torque of the Decelerator. Take care so that this value is not exceeded.
Note:
1. The Decelerator inertia is the Servomotor shaft conversion value.
2. The protective structure rating of the Servomotor combined with the Decelerator is IP44. (Excluding decelerator and servo motor connecting parts.)
3. The Allowable radial load column shows the values obtained at the center of the shaft (T/2).

4. The standard shaft type is a shaft with key and tap. (The key is temporarily assembled to the shaft.)
5. Take care so that the surface temperature of the Decelerator does not exceed 90°C.
