DC BUS over-voltage during
acceleration
(230V: DC 405V; 460V: DC
810V)
1. Check if the input voltage falls within the rated
brushless DC 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
DC BUS over-voltage during
deceleration
230V: DC 405V; 460V: DC
810V
1. Check if the input voltage falls within the rated
brushless DC 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
DC BUS over-voltage during
constant speed
230V: DC 405V; 460V: DC
810V
1. Check if the input voltage falls within the rated
brushless DC 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
DC BUS over-voltage at stop 1. Check if the input voltage falls within the rated
brushless DC motor drive input voltage range.
2. Check for possible voltage transients.
DC BUS voltage is less than
Pr.06-00 during acce leration . 1. Check if the input voltage is normal
2. Check for possible sudden load
DC BUS voltage is less than
Pr.06-00 during de celeration 1. Check if the input voltage is normal

DC BUS voltage is less than
Pr.06-00 during constant
speed.
1. Check if the input voltage is normal
2. Check for possible sudden load
Low vo ltage at stop
1. Check if the input voltage is normal
2. Check for possible sudden load
Phase loss Check Power Source Input if all 3 input phases are
connected without loose contacts.
