Protective Features
Power Loss Ride-thru
Seconds
Stop after 15 ms power loss ride-thru
(factory setting)
Continuous operation during power loss of
< 0.5 s. (standard)
Back-up capacitor Option
Motor Overload UL Recognized
Protects motor from overheat based on output
current
Motor Switch Input ~ Yes (external fault input)
Drive Overload ~
Drive will stop after operating continuously at
100% rated output current or at 150% for 60 s
(Heavy Duty)
Low speed overload: 100% continuous, 150%
0.5 s
Over Voltage ~
Yes, Motor coasts to stop when DC bus
voltage is:
>410 Vdc for (230 V models)
>820 Vdc for (460 V models)
Under Voltage ~
Drive stops when DC bus voltage falls below
the levels indicated:
160 V (200 V Single Phase)
190 V (200 V class)
350 V (Refer to E1-01 on page 355)
380 V (400 V class)
UV 50% possible (reactor required)
Phase Loss
Input Yes, enable/disable is user selectable
Output Yes, enable/disable is user selectable
Short Circuit
Phase-to-Phase Yes
Ground fault
Yes, Electronic circuit protection
(triggered by the same levels as momentary
current protection)
Overcurrent Software and Hardware
Yes, Hardware (OC) + Software Detection
Drives stops when rated output current
exceeds 200%
Braking Transistor (built-in) Failure
Separate detection output for braking
transistor failure
Stall Prevention ~
Yes, user selectable stall levels with
intelligent function, during run, decel or accel
Mechanical Contactor
Failure
~
Available
(thermistor prevents burn-up when power is
switched on)
Torque Limit ~ Yes (open-loop vector mode)
Torque Detection (Over
Torque/Under Torque)
~Yes
