GD20-09INVT
GD20-09 — Compact Hoisting VFD .
Goodrive20-09 Series VFD for Hoisting
Compact VFD for electric hoists, European-type cranes and small-tonnage bridge and gantry cranes: 3-ph 380–440 V, 0.75–37 kW (output current 2.5–75 A). SVPWM (V/F) and SVC control of induction motors, 150 % torque at 0.25 Hz, output 0–150 Hz, S3 duty. A braking unit is built into every model, a DC reactor from 18.5 kW. Built-in brake logic and conical-rotor motor control, torque verification, brake feedback and zero-position monitoring, travel limits and PTC motor protection. Mounting area is 60 % smaller than the previous generation.
