Motor overheat protection via output current sensor
Drives stops when output exceeds 200% of the rated current (Heavy Duty)
A stop command will be entered after operating at 150% for 60 s (Heavy
<3>
Duty)
Drive stops when DC bus voltage falls below the levels indicated:
190 V (3-phase 200 V), 160 V (single-phase 200 V), 380 V (3-phase 400 V), 350
V (3-phase 380 V)
Stops after 15 ms
Protected by thermistor
During acceleration and during run: Separate settings for each type of stall
prevention determine the current level at which stall prevention is triggered.
During deceleration: Select, enable/disable.
Circuit protection ("fan-lock" sensor)

Install the drive in an area free from:
• oil mist and dust
• metal shavings, oil, water or other foreign materials
• radioactive materials
• combustible materials
• harmful gases and liquids
• excessive vibration
• chlorides
• direct sunlight
Install the drive vertically to maintain maximum cooling effects
