Motor Protection 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 Duty)
200 V class: Stops when DC bus voltage exceeds approximately 410 V
400 V class: Stops when DC bus voltage exceeds approximately 820 V
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

Heatsink Overheat
Protected by thermistor
Protection
Overheat input signal for braking resistor (Optional ERF-type, 3% ED)
Protection
During acceleration and during run: Separate settings for each type of stall prevention
Stall Prevention determine the current level at which stall prevention is triggered.
During deceleration: Select, enable/disable.
Circuit protection ("fan-lock" sensor)
Protection
Electronic circuit protection
Remains lit until DC bus voltage falls below 50 V
