PRODUCT DETAILS
20G11ND034JA0NNNNN — 755 Series AC Drive, 480V Three-Phase, 25 HP / 20 HP, Filtered, Frame 3
The 20G11ND034JA0NNNNN is a 755 series AC drive rated at 34A output current, delivering 25 HP Normal Duty or 20 HP Heavy Duty from a 480V AC three-phase input (650V DC bus). It ships in a Frame 3 housing with the integral EMC filter and common-mode jumper installed, an internal dynamic braking transistor, embedded EtherNet/IP, and a blank cover in place of a HIM — a standard configuration suited to installations where local keypad access isn't the primary control method.

A Filtered Frame 3 Drive for Standard Installations
This configuration's filter and CM jumper being installed reflects the most common standard installation scenario — a grounded supply system where the filtered configuration provides CE-compliant EMC performance without requiring an external filter to be added separately. The internal brake transistor at this frame size means dynamic braking is achievable by adding only an external resistor, rather than requiring a separate brake module, which simplifies the bill of materials for applications needing controlled fast deceleration.
Five option slots give this drive considerable configuration flexibility after the initial purchase — feedback cards for closed-loop vector or motion applications, safety option cards for hardwired or network-based safety functions, and additional communication cards can all be added into the same chassis as application requirements evolve, without needing a different base drive.
FAQ
Q: Does this drive include a HIM for local operation?
No. This configuration ships with a blank cover in place of a HIM. A compatible HIM module can be added afterward if local keypad access becomes necessary.
Q: Is an external resistor required for dynamic braking?
Yes. The internal brake transistor handles the switching, but an appropriately sized external resistor must be connected for the braking energy to actually be dissipated.
Q: Should the EMC filter and CM jumper be removed for an ungrounded supply system?
Generally yes — installations on ungrounded or high-resistance grounded AC systems typically require the filter and CM jumper removed to avoid excessive leakage current. Verify against the drive's installation documentation for the specific supply configuration in use.
Q: Can closed-loop vector control be added to this drive later?
Yes, through the feedback option slot — installing a compatible feedback card and the associated encoder wiring enables closed-loop vector operation without changing the base drive.
