200 AC servo systems
Iron-core SGLFW/SGLFM (200 V)
Note: 1. The items marked with an * and “force and speed characteristics” are the values at a motor winding temperature of 100
°
C during oper-
ation in combination with a servo drive. 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.
