Notes: 1 When the effective force during intermittent duty is within the rated force, the servomotor can be used within the intermittent duty zone.
2 The dotted line indicates the characteristics when a 400-VAC linear servomotor is used with 200-V input power supply. In this case, a serial converter unit is required. Contact
your Yaskawa representative for details.
