P5-09
Over Voltage Current
Limit
0 to 100% of motor rated current
%
0
This parameter is only valid in
vector speed control mode.
This parameter will come into
function once the drive DC bus
voltage increase over certain
limit. This voltage limit is set
internally just below the over
voltage trip level. This parameter
will effectively limit the output
torque current in order to
prevent large current going back
to the drive, which may cause
over voltage trip.
A small value in this parameter
will limit the motor control
torque once drive DC bus over
this control level. A higher value
may cause big distortion on the
motor current, which may cause
an aggressive behavior of the
motor.
P5-10
Re-Generation Current
Limit
0.0 to 200% of motor rated
current
%
100.0
This parameter defines the
control current limit when motor
in regenerating mode. The value
in this parameter represents the
percentage value of motor rated
current that is defined in P1-08.
The current limit that defined in
this parameter will override the
normal torque producing current
limit when motor goes into
regeneration mode.
Too high a value may cause
big motor current distortion
and the motor may behavior
aggressively once motor goes
into regeneration mode. The
output torque of the motor may
reduce during regeneration if the
value in this parameter is too
small.
P5-11
Pulse Width Limitation
0...500
(Time = value *16.67ns)
Ms
-
This parameter is used to limit
the minimum output pulse width,
which can be used for long
cable applications. Increasing
the value of this parameter will
reduce the risk of
over-current trips on long motor
cables, but will also reduce
the maximum available output
motor voltage for a given input
voltage.
P5-12
V/F Mode Magnetizing
Period
0…2000ms
ms
-
This parameter is used to set up
a minimum delay time for the
magnetizing current control in
V/F mode when drive run signal
is given. Too small a value may
cause the drive to trip on over-
current if the acceleration ramp
is very short.
