Standard Models and Specifications
• 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
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.
