Sigma linear axis 223
Linear axis LETLA-@-F@@A (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 °Cduring
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.
