Default Usage
Size related This parameter corresponds to the inductance saturation of
Lq. Ideally, this parameter has the same value as parameter
1-38 q-axis Inductance (Lq). However, if the motor supplier
provides an induction curve, enter the induction value, which
is 200% of the nominal current.
100% Adjusts the height of the test pulse during position detection
at start.
100% Enter the inductance saturation point.
100% This parameter specifies the saturation curve of the d- and q-
inductance values. From 20–100% of this parameter, the in-
ductances are linearly approximated due to parameter 1-37 d-
axis Inductance (Ld), parameter 1-38 q-axis Inductance (Lq), pa-
rameter 1-44 d-axis Inductance Sat. (LdSat), and parameter 1-45
q-axis Inductance Sat. (LqSat).
[0] Rotor De- Select the PM motor start mode.
tection
[0] Disabled Select [1] Enabled to enable the drive to catch a spinning mo-
tor in, for example, fan applications. When PM is selected, this
parameter is enabled.
0 The minimum reference is the lowest value obtainable by
summing all references.
50 The maximum reference is the highest value obtainable by
summing all references.
0 Enter the setpoint.
Size related Ramp-up time from 0 to rated parameter 1-23 Motor Frequen-
cy for asynchronous motors. Ramp-up time from 0 to parame-
ter 1-25 Motor Nominal Speed for PM motors.
Size related Ramp-down time from rated parameter 1-23 Motor Frequency
to 0 for asynchronous motors. Ramp-down time from param-
eter 1-25 Motor Nominal Speed to 0 for PM motors.
0.0 Hz Enter the minimum limit for low speed.
100 Hz Enter the minimum limit for high speed.
