D Servomotor and Mechanical System Temperature Characteristics
Caution Do not use 900-W, 2-kW, 4-kW, or 5.5-kW Servomotors within the shaded portions of the
• W-series AC Servomotors use rare earth magnets (neodymium–iron magnets). The temperature
• Generally, in a mechanical system, when the temperature drops the friction torque increases and the
• An increase in load friction torque visibly increases load inertia. Therefore, even if the Servo Driver
coefficient for these magnets is approximately –0.13%/°C. As the temperature drops, the Servomo-
tor’s momentary maximum torque increases, and as the temperature rises the Servomotor’s mo-
mentary maximum torque decreases. When the normal temperature of 20°C and –10°C are
compared, the momentary maximum torque increases by approximately 4%. Conversely, when the
magnet warms up to 80°C from the normal temperature of 20°C, the momentary maximum torque
decreases by approximately 8%.
load torque becomes larger. For that reason, overloading may occur at low temperatures. In particu-
lar, in systems which use deceleration devices, the load torque at low temperatures may be nearly
twice the load torque at normal temperatures. Check with a current monitor to see whether overload-
ing is occurring at low temperatures, and how much the load torque is. Likewise, check to see wheth-
er there abnormal Servomotor overheating or alarms are occurring at high temperatures.
parameters are adjusted at a normal temperature, there may not be optimal operation at low temper-
atures. Check to see whether there is optimal operation at low temperatures too.
