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 motor spin-
ning due to mains drop-out. Select [0] Disabled if this function
is not required. When this parameter is set to [1] Enabled, pa-
rameter 1-71 Start Delay and parameter 1-72 Start Function are
not functional. Parameter 1-73 Flying Start is active in VVC
mode only.
0 The minimum reference is the lowest value obtainable by
summing all references.
50 The maximum reference is the lowest obtainable by summing
all references.
Size related If asynchronous motor is selected, the ramp-up time is from 0
to rated parameter 1-23 Motor Frequency. If PM motor is selec-
ted, the ramp-up time is from 0 to parameter 1-25 Motor Nom-
inal Speed.
Size related For asynchronous motors, the ramp-down time is from rated
parameter 1-23 Motor Frequency to 0. For PM motors, the
ramp-down time is from parameter 1-25 Motor Nominal Speed
to 0.
0 Hz Enter the minimum limit for low speed.
100 Hz Enter the maximum limit for high speed.
