CFW500A01P0T4NB20G2

Update August 2022:

Due to a component issue, the G2 series will have immediate changes. The changes below are expected to remain until mid-2023, at that point all models are expected to be available as G2 again.

• IP20 versions, Frame size A through E will only be available as the previous version (G1)
• IP20 versions, Frame size F and G will remain available as the current G2 model
• IP66/NEMA 4 versions, Frame size A and B will remain available as the current G2 model

Below you will find the features that the G2 offered that the G1 does NOT have:

• Features the G1 series does not offer (that were features of G2):
• STO (Safe Torque Off) - CFW500-SFY2
• Remote Advanced Text Keypad (HMI-01)
• BACnet Communications
• ND/HD ratings for frame E
• Pump Genius- Multiplex
• Field upgradable FM using WMS
• WPS compatibility
• VFD parameters copy/paste using advanced text keypad (HMI-01)
• VFD paramenters copy/paste using I/O module
• SoftPLC program stored in control board

We apologize for any inconvenience this has caused, there was very little notice given by the end supplier of the component.

CFW500 Series:

Looking for any easy-to-use drive that has the flexibility your application needs?

The CFW500 has easy to configure advanced technology options, developed for fast commissioning while offering excellent performance and reliability.
