VERVIEW
This menu contains the nominal parameters of the mains, the motor drive activation logic and the drive
operation when the mains is out of range.
C502 sets whether the drive locks due to a fault trip or is temporarily disabled and automatically restarts as
soon as the mains fault disappears (when the mains is OK, the REF LED in the keypad comes on).
C503 sets the motor drive status based on the regenerative drive status (MDO4 control logic; MDO4 is the
digital output used for the motor drive activation):
C503 Setting
MDO4 Status
Condition
What happens
CLOSED (motor
drive enabled)
The regenerative drive is
enabled; the pre-charge
of the internal capacitors
is complete.
1
ENABLED
OPEN (motor
drive disabled)
The regenerative drive is
disabled or the pre-
charge contactor is not
closed.
The motor drive is always enabled when
the regenerative drive is enabled and the
pre-charge contactor is closed.
Faults in the regenerative drive or mains
voltage out of range condition do not
stop the system. When the RGN drive is
locked, sinusoidal absorption and
braking energy delivery to the mains will
stop.
CLOSED (motor
drive enabled)
The regenerative drive is
enabled; the pre-charge
of the internal capacitors
is complete; possible
fault, but the drive is
waiting for the autoreset
signal.
2
RESET OR
RUNNING
OPEN (motor
drive disabled)
The regenerative drive is
disabled, or the pre-
charge contactor is not
closed, or an alarm
tripped, that cannot be
automatically reset.
The motor drive is always enabled when
the regenerative drive is enabled and the
pre-charge contactor is closed.
Faults in the regenerative drive or mains
voltage out of range condition do not
stop the system if the Autoreset function
is active and the autoreset attempts are
not over. When the RGN drive is locked,
sinusoidal absorption and braking
energy delivery to the mains will stop
and will be resumed as soon as the
alarm is reset.
CLOSED (motor
drive enabled)
The regenerative drive is
running or is disabled
because the mains is out
of range; no alarm
tripped.
3
RUNNING
OPEN (motor
drive disabled)
The regenerative drive is
not running (ENABLE
open), or an alarm
tripped.
The motor drive is enabled only when the
regenerative drive is running or is
disabled when the mains is out of range
and the relevant alarms are disabled.
