3.1 Ratings and Specifications of SGLGW/SGLGM
(1) Ratings and Specifications
(a) With Standard-force Magnetic Ways
The following table shows the ratings and specifications when the standard-force magnetic ways are used.
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).
• Time Rating: Continuous
