Fault Descriptions
Hardware failure in
current detection
DC BUS over-voltage
during acceleration
(230V: DC 450V; 460V:
DC 900V)
DC BUS over-voltage
during deceleration
(230V: DC 450V; 460V:
DC 900V)
DC BUS over-voltage at
constant speed (230V: DC
450V; 460V: DC 900V)
Hardware failure in
voltage detection
DC BUS voltage is less
than Pr.06-00 during
acceleration
DC BUS voltage is less
than Pr.06-00 during
deceleration
DC BUS voltage is less
than Pr.06-00 in constant
speed
DC BUS voltage is less
than Pr.06-00 at stop
Corrective Actions
Return to the factory
1. Check if the input voltage falls within the rated AC
motor drive input voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative
voltage, please increase the acceleration time or
add an optional brake resistor.
1. Check if the input voltage falls within the rated AC
motor drive input voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative
voltage, please increase the Deceleration Time or
add an optional brake resistor.
1. Check if the input voltage falls within the rated AC
motor drive input voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative
voltage, please increase the Deceleration Time or
add an optional brake resistor.
1. Check if the input voltage falls within the rated AC
motor drive input voltage range.
2. Check for possible voltage transients.
1.
