ov Over voltage
The DC link voltage has
exceeded its maximum
allowable value.
PWM
inhibit
m Check if the input voltage falls within the
rated device input voltage range.
m Check for possible voltage transients.
m DC link over-voltage may also be caused
by motor regeneration. Either increase
the deceleration time or add an optional
braking resistor (and brake unit).
m Check whether the required braking pow-
er is within the specified limits.

GFF Ground fault PWM
inhibit
When (one of) the output terminal(s) is
grounded, short circuit current is more than
50
% of b maXX
®
rated current, the drive
power module may be damaged.
NOTE: The short circuit protection is provid-
ed for b maXX
®
drive protection, not for
protection of the user.
m Check whether the IGBT power module
is damaged.
m Check for possible poor insulation at the
output line.

oL1 Overload 1
I²t > 100 %
PWM
inhibit
m Check for possible motor overload.
m Check electronic thermal overload set-
ting.
m Use a higher power motor.
m Reduce the current level so that the drive
output current does not exceed the value
set by the Motor rated current P0054.

P0862
m Check the RS485 connection between
the b
maXX
®
drive and RS485 master
for loose wires and wiring to correct pins.
m Check if the communication protocol, ad-
dress, transmission speed, etc. are prop-
erly set.
m Use the correct checksum calculation.
