Notes
(Factory
Setting)
Sets the dc injection voltage as a percentage of
00.0 –
the mains voltage. The optimum setting is
20.0%
dependent on motor type and inertia. Too high a
level will result in overcurrent and tripping of the
drive (F00). Too low a level will result in longer
than necessary stopping times. DC injection
braking is enabled automatically when P11 is
set to a non–zero value.
(00.0)
Sets the inverter frequency reached when the
00.1 –
400 Hz jog control input is active. Overrides the
minimum frequency setting.
(05.0)
Sets the amount of slip compensation (Hz) added
00.0 –
to the output frequency when a current equal to
20.0 Hz
the current limit (set via P17) is supplying the
motor.
Note that excessive slip compensation will cause
the motor to increase speed above that
equivalent to the original set output frequency
and overloading may result.

f = f + (P13 x measured load current/P17)

This parameter sets the current limit of the
00.1 –
inverter in amperes. This current limit operates
inverter
after 60 s (P18 sets the overload limit) by
rated
reducing the output frequency until the output
output in
