635/637F Series Servo Drives
2 to 30A

Torque, speed, position or motion control and built-in I/O are all standard features of the 635/637F series Brushless Servo drive. Each
model has an internal power supply allowing direct connection to the supply. 635 models are 230 VAC rated and 637F models are rated for
either 230 or 460 VAC supplies. They become part of a total servo package including motors, servo gearboxes and interconnecting cables.

The 635/637F is available as a stand-alone drive or as a rack mounted module with up to 9 drives in a single rack.
