Parameter Descriptions
SP-10 Line failure
Options [1] Ctrl. ramp-down, [2] Ctrl. ramp-down, trip, [5] Kinetic
back-up, trip, [7] Kin. back-up, trip w recovery are not active when
the option [2] Torque is selected in parameter H-40 Configuration
Mode.
Option:
Function:
If mains return while in kinetic back-up at a
speed below parameter SP-15 Kin. Backup Trip
Recovery Level, the frequency converter ramps
down to 0 RPM using the ramp and then trips. If
the ramp is slower than the system ramping
down on its own, the ramping is done mechan-
ically and U
is at the normal level (U
DC
A Normal operation.
B Mains failure.
C Kinetic back-up.
D Mains return.
E Kinetic back-up, ramping to trip.
F Trip.

Recovery, Trip Slow Ramp where Mains
Returns below Parameter SP-15 Kin. Backup
Trip Recovery Level, in this Illustration a Slow
Ramp is Used
If the ramp is quicker than the ramp down
speed of the application, the ramping generates
current. This results in a higher U
limited using the brake chopper/resistor brake.

SP-12 Function at Line Imbalance
Operation under severe main imbalance conditions reduces the
lifetime of the motor. Conditions are considered severe if the
motor is operated continuously near nominal load (for example,
a pump or a fan running near full speed).

which the function in parameter SP-10 Line
failure is activated. Select the detection level
depending on the supply quality. For a supply
of 380 V, set parameter SP-11 Line Voltage at
Input Fault to 342 V. This results in a DC
detection level of 462 V (parameter SP-11 Line
Voltage at Input Faultx1.35).

Trips the frequency
