Note: 1. The items marked with an * and "Force and Speed Characteristics" are the values at a motor winding tem-
perature of 100 °C (212°F) during operation in combination with a SERVOPACK. The others are at 20 °C
(68°F).
2. The above specifications show the values under the cooling condition when a heat sink (aluminium board)
listed in the following table is mounted on the coil assembly.
