Note:
*1.
These items and speed/torque characteristics quoted in combination with an SJDE servo drive are at an armature winding temperature of 100°C. Other
values quoted at 20°C.
*2:
The rated torques listed here are the values for the continuous allowable torque at 40°C with an aluminium heatsink (250 mm x 250 mm x 6 mm) attached.
*3.
Value usig the appropriate SJDE drive without of external regeneration unit
