G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
*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.
The following tables show the performance specifications of various ironless Linear Motor models.
