Parameters for “Current limiting” operating mode
Description
When the drive starts, the MOVIFIT
®
compact motor starter imposes the current I
e
into
the motor. The current I
e
is defined with parameter
P13 Current limit
. The motor accel-
erates depending on the motor current I
M
.
Time t
I
is used to monitor the starting procedure. Within the monitoring time t
I
, the mo-
tor current must have left its increased startup value and have dropped to the nominal
current or below. If the motor is still carrying a current that is greater than the nominal
motor current after monitoring time t
I
, the MOVIFIT
®
compact motor starter switches to
fault condition F 34 (Start time monitoring error); see chapter "MOVIFIT
®
compact mo-
tor starter error list" (→
89).
