Ser2 Flt Tol
[A168]
(Serial Mode 2 Fault Tolerance)
Used only
with custom serial protocol (mode 2)
When
in Serial Mode 2, this parameter defines the
maximum time that may elapse between
valid run time messages while in serial run
mode before a serial fault is declared.

Mains Dip
Speed
[A169]
(Mains Dip Speed Multiplier) This parameter
sets a limit on the speed the drive will turn
the motor, as a percentage of contract
speed. The Mains Dip function is enabled
by the Mains Dip Enable (MAINS DIP
ENA(C1)) parameter. When the drive goes
into ‘low voltage’ mode, it limits the speed to
the percentage defined by this parameter.
‘Low voltage’ mode is defined as when the
drive declares a UV alarm, which is defined
by the Input line-to-line voltage (INPUT L-L
VOLTS(A4)) parameter and the
Undervoltage Alarm Level (UV ALARM
LEVEL(A4)).

output. Units in percent of contract speed.
