Description
Unfiltered motor torque in percent of the nominal
motor torque.
Note: This parameter is read-only.
Unfiltered motor torque.
For scaling, see parameter 46.3.
Defines a filtering time for estimated speed See the
diagram on page 747.
Filtering time for estimated speed.
This parameter is not in use.
Defines current reference for controlling low-speed
current if parameter 97.91 Low speed current control
enable is activated.
Percentage of motor nominal current.
Defines the speed level for controlling low speed
current when parameter 97.91 Low speed current
control enable is activated.
Below this speed, current follows the reference defined
in parameter 97.92.
• When frequency reference of inverter is ramped
above this value, a smooth transition to normal
scalar control starts.
• When frequency is approximately the sum of this
value and 20% of nominal frequency, then current
controller is completely turned off. Scalar control
follows U/f curve or energy optimizer's voltage
reference.
Percentage of motor nominal frequency.
Defines INU output power factor (cos phi) used in
permanent magnet motor scalar control.
The parameter is effective only when parameter
Energy optimizer is enabled. The Energy optimizer
function is disabled if this value is set to zero. In this
case, to tune the operating point of the drive and if
current must lead the voltage, a negative value is set.
For example, - 0.990 means voltage is 8.1 degree behind
current.
