Iron-core SGLFW/SGLFM (400 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.
Force-speed characteristics (400 V)
Note: The dotted line indicates characteristics when the linear servo motor for 400 VAC is used with an input power supply for 200 VAC. In this
case, the serial converter should be changed. Contact your OMRON Yaskawa representatives.
