Description
Current used in the current vector rotation at low speeds.
Increase the smooth start current if the application requires
motor shaft swinging needs to be minimized. Note that
accurate torque control is not possible in the current vector
rotation mode.
Can be used for permanent magnet synchronous motors
only.
Value in percent of the nominal motor current.
Output frequency up to which the current vector rotation is
used. See parameter 21.19 Scalar start
Can be used for permanent magnet synchronous motors
only.
Value as a percentage of the nominal motor frequency.
Defines the maximum supplied current to motor when
Scalar start mode is set to
Parameter value is in percent of the motor nominal current.
Nominal value of the parameter is 100.0%.
Torque boost is only applied at start, ending when output
frequency exceeds 40% of nominal frequency or when output
frequency is equal to reference.
Can be used in scalar mode only.
Value in percent of the nominal motor current.
Forces automatic restart. The parameter is applicable only if
parameter 95.04 Control board supply
Force auto restart disabled. Parameter
time is in effect if its value is more than 0.0 s.
Force auto restart enabled. Parameter
is ignored. The drive never trips on the undervoltage fault and
the start signal is on forever. When he DC voltage is restored,
the normal operation continues.
