Frequently Asked Questions
Is VFD185C43A-21 suitable for a crane or hoist?
Yes. The C2000 is Delta’s heavy duty vector drive, with 150% overload for 60 seconds, torque control with and without encoder feedback and a built-in PLC, which makes it the usual choice for hoisting and lifting.
Does VFD185C43A-21 have a built-in EMC filter?
Optional external filter. Models with an S in the version field carry a built-in EMC filter; models with an A take an external filter kit when EMC compliance is required.
What is the difference between C2000 and C2000 Plus?
C2000 Plus is the current generation. It uses the same model numbering and the same ratings, but adds a faster processor, more PLC program steps, a built-in CANopen master and improved permanent magnet motor control.
Can VFD185C43A-21 run a permanent magnet motor?
Yes. The C2000 supports PM motor control with and without encoder feedback, in addition to induction motor V/F, sensorless vector and closed loop vector modes.
