Protection
Functions
Motor Protection Motor overheat protection via output current sensor
Overcurrent Protection Drives stops when output exceeds 200% of the rated current (Heavy Duty)
Overload Protection
A stop command will be entered after operating at 150% for 60 s (Heavy Duty)
<4>
Low Voltage Protection
Drive stops when DC bus voltage falls below the levels indicated:
<5>
190 V (3-phase 200 V), 160 V (single-phase 200 V), 380 V (3-phase 400 V), 350 V (3-
phase 380 V)
Momentary Power Loss Ride-Thru
3 selections available: Ride-Thru disabled (stops after 15 ms), time base of 0.5 s, and
continue running as long as the drive control board is powered up.
<6>
Heatsink Overheat Protection Protected by thermistor
Braking Resistor Overheat Protection Overheat input signal for braking resistor (Optional ERF-type, 3% ED)
Stall Prevention
Stall prevention is available during acceleration, deceleration, and during run. Separate
settings for each type of stall prevention determine the current level at which stall
prevention is triggered.
Cooling Fan Failure Protection Circuit protection (“fan-lock” sensor)
Ground Protection
Electronic circuit protection
<7>
DC Bus Charge LED Remains lit until DC bus voltage falls below 50 V
