Drive
Specifications Section 1
NOTES:
(1) Based on an N.E.C. standard 4-pole motor for max. applicable motor output.
(2) Shows deceleration torque for an uncoupled motor decelerating from 60 Hz in 0.1 seconds.
(3) Contact Yaskawa for wiring distances greater than 328 ft. (100 m).
(4) Temperature during shipping (for short periods of time).
(5) On NEMA type 4X/12 model only, maximum continuous rating of 30.8 A is 40 degrees C maximum ambient. For 33.0 A maximum
continuous rating, maximum ambient is 32 degrees C.
(6) Applies to NEMA type 4X/12 model only.
(7) On Model 47P5 NEMA type 4X/12 (21A), overload is 120% for 1 minute.
