Function
Selection This parameter is used to
retain the held frequency
reference in U1-01 (d1-01)
when power is removed. This
function is available when the
multi-function inputs “accel/
decel ramp hold” or
“up/down” commands are
selected (H1-XX = A or 10
and 11).

Trim Control
Lvl Sets the amount of frequency
reference to be added or
subtracted as a percentage of
maximum output frequency
(E1-04) when multi-function
inputs “trim control increase”
and “trim control decrease”
are selected (H1-XX = 1C
and 1D).

Torque
Control
Selection Selects speed or torque control.
The torque reference is set via
analog input A2 or A3 when it
is set for "torque reference"
(H3-05 or H3-09 = 13). Torque
reference is set as a percentage
of motor rated torque. To use
this function for switching
between speed and torque
control, set to 0 and set a multi-
function input to "speed/torque
control change" (H1-xx = 71).
0: Speed Control (controlled
by C5-01 to C5-07)

Reference
Delay Time Sets the torque reference
delay time in milliseconds.
This function can be used to
correct for noise in the torque
control signal or the
responsiveness with the host
controller. When oscillation
occurs during torque control,
increase the set value.
