You only linked the family of servo drives and didn't provide a specific model, however the 100V servos are listed in the technical docs as 100VAC to 120VAC -15% to +10% for voltage range on the 100V single-phase drives. Just wire it up, unless you have something that is putting abnormal spikes on your line.
Do make sure it's listed as an appropriate pair with the servos you have. If you purchased it from a Yaskawa vendor then that shouldn't need to be checked.
The 100V single phase only pairs with up to 400W servos, fyi.
