Protection Function
Motor Protection Motor overheat protection based on output current
Momentary Overcurrent Protection Drive stops when output current exceeds 200% of rated output current.
Overload Protection
Drive stops after
60 s at 150% of rated output current.
Note
:
The drive may trigger the overload protection function at
150% of the drive rated output in under 60 s if the
output frequency is less than
6 Hz.
Overvoltage Protection
200 V class
:
Stops when DC bus exceeds approx. 410 V
400 V class
:
Stops when DC bus exceeds approx. 820 V
Undervoltage Protection
200 V class
:
Stops when DC bus falls below approx. 190 V
400 V class
:
Stops when DC bus falls below approx. 380 V
Heatsink Overheat Protection Thermistor
Braking Resistance
Overheat Protection
Overheat sensor for braking resistor
(
optional ERF
-
type, 3% ED
)
Stall Prevention Stall prevention during acceleration/deceleration and constant speed operation
Ground Fault Protection
Protection by electronic circuit
Note
:
Protection may not be provided under the following conditions as the motor windings are grounded internally during run
:
Low resistance to ground from the motor cable or terminal block.
Drive already has a short
-
circuit when the power is turned on.
Charge LED Charge LED remains lit until DC bus has fallen below approx. 50 V
