• SMARTSTEP A-series Servomotors use rare earth magnets (neodymium-iron magnets). The tem-
• Generally, in a mechanical system, when the temperature drops the friction torque increases and
• An increase in load friction torque visibly increases load inertia. Therefore, even if the Servo Driver

perature coefficient for these magnets is approximately –0.13%/ ° C. As the temperature drops, the
Servomotor’s momentary maximum torque increases, and as the temperature rises the Servomo-
tor’s momentary 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%.
the load torque becomes larger. For that reason, overloading may occur at low temperatures. In
particular, in systems which use reduction gear, the load torque at low temperatures may be nearly
twice the load torque at normal temperatures. Check with a current monitor to see whether over-
loading is occurring at low temperatures, and how much the load torque is. Likewise, check to see
whether 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 tem-
peratures. Check to see whether there is optimal operation at low temperatures too.
