0: Speed Control
1: Torque Control
Set to 0 when using a digital input to switch between Speed and Torque Control
(H1-oo = 71).
V/f V/f w PG
OLV/PM AOLV/PM
Sets a delay time for the torque reference signal. Used to suppress effects by
noisy or fluctuating torque reference signals.

1: Limit set by the frequency reference in b1-01.
2: Limit set by d5-04.
V/f V/f w PG
OLV/PM AOLV/PM
Sets the speed limit during Torque Control as a percentage of the maximum
output frequency. Enabled when d5-03 = 2. A negative setting set a limit in
the opposite direction of the Run command.
V/f V/f w PG
OLV/PM AOLV/PM
Sets the speed limit bias as a percentage of the maximum output frequency.
The bias is applied to the specified speed limit and can adjust the margin for
the speed limit.
V/f V/f w PG
OLV/PM AOLV/PM
Sets the delay time for switching between Speed and Torque Control using an
input terminal (H1-oo = 71). Reference values are held during this switch
delay time.

OLV/PM AOLV/PM
Sets the drive output voltage for the Field Weakening function as a percentage
of the maximum output voltage.
Enabled when a multi-function input is set for Field Weakening (H1-oo =
63).
V/f V/f V/f w PG V/f w PG
OLV/PM AOLV/PM
Sets the lower limit of the frequency range where Field Weakening control is
valid.
The Field Weakening command is valid only at frequencies above this setting
and only when the output frequency matches the frequency reference (speed
agree).
