(200 V)
Note: *1. The items marked with an *1 and “Force and speed characteristics” are the values at a motor winding temperature of 100
°
C
during
operation in combination with a servo drive. The others are at 20
°
C (68
°
F).
*2. With stable environmental conditions and motor temperature unchanged.
*3. Items calculated with load position like in figure below.
