G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
3-3 Linear Motor Specifications
Two types of Linear Motors are available: Iron-core and Ironless Linear Motors.
These Linear Motors consist of one Motor Coil Unit and two or more Magnet Track.
The Motor Coil Unit has built-in temperature sensors.
Choose an appropriate Linear Motor model based on the load and the operating characteristics.
*1 The amplitude may be increased by machine resonance. As a guideline, do not exceed 80% of the specified
value.
*2 Disconnect all connections to the Linear Motor before attempting a megameter test (insulation resistance
measurement) on a Linear Motor. Failure to follow this guideline may result in damaging the Linear Motor. In
addition, never perform dielectric strength tests on the Linear Motor. Failure to follow this guideline may result
in damaging the internal elements.
