H10 Red It lights up to indicate a power rectifier heat sink overtemperature
H11 Red It lights up to indicate overtemperature of the air inside the drive
H12 Red IGBT U
H13 Red IGBT V
H14 Red IGBT W
It lights up in case of overtemperature of one of the IGBT devices.
The signal temperature relating to the hotter of the master and slave IGBT devices
is sent to the regulation card.
A temperature signal is also sent automatically to the regulation card in case
of minimum temperature, which could occur in the event of a fault in one of the
H15 Red
temperature reading circuits.
The loss of one of the temperature signals is indicated by LED H15, with the code
indicated by the number of flashes (*): the sequence of flashes to indicate the
faulty PHASE or SLAVE has a 3Hz frequency and is repeated cyclically every 5
seconds.
It lights up on the INT-P-ADV MASTER card to indicate that the drive's total current
(master + slave) has exceeded the overcurrent value for the size of drive, whereas
H18 Red
it lights up on the INT-P-ADV SLAVE card to indicate that the SLAVE current has
only exceeded the overcurrent value of the SLAVE.
H19 Red It lights up to indicate a fault on the DC-BUS power supply regulation card
They light up to indicate a short circuit between the output phases
They light up to indicate loss of the feedback signal relating to the mo-
ment the IGBT devices are switched on. The signal is used for hardware
dead time compensation
