ECO REFERENCE MANUAL
13-10
Ramp-down time 0-2
[0]
This is the time taken for the motor to
decelerate from maximum frequency to
standstill. The maximum frequency is set by
parameter P013. Setting the ramp-down
time too short can cause the inverter to trip
(Fault code F001 = DC link overvoltage).
This is also the period for which injection
braking is applied, if selected (refer to
parameter P073 in Expert mode).
Digital frequency setpoint

Sets the frequency that the inverter will run
at when operated in digital mode. Only
effective if P006 = 0 or 3.
Frequency setpoint source
selection
0-2
[0]
The value of this parameter 0, 1or 2) selects
the mode of control of the inverter’s
frequency setpoint.
0 = Digital motorised potentiometer
(Keypad control potentiometer).
The inverter runs at the frequency set in
P005 (refer to Expert mode) and can be
controlled with the [
up
] and [
down
] keys. If
P007 (see below) is set to 0, the frequency
can be increased or decreased by setting
any two of the digital inputs (P051 to P055
or P356 - refer to Expert mode) to the
values of 11 and 12.
1 = Analogue. The inverter output
frequency is controlled by analogue input
signals (0-10V, 0/4-20mA or potentiometer).
2 = Fixed frequency. Fixed
frequency is only selected by setting the
value of at least one of the digital inputs
(P051 to P055 or P536 - refer to Expert
mode) to the value of 6 or 18.
