Description
Jump Frequencies
These parameters allow programming of up to three prohibited
frequency reference points for eliminating problems with resonant
vibration of the motor / machine. This feature does not actually
eliminate the selected frequency values, but will accelerate and
decelerate the motor through the prohibited bandwidth.
This parameter determines the width of the deadband around each
selected prohibited frequency reference point. A setting of "1.0"
will result in a deadband of +/- 1.0Hz.
Sequence (MOP & Trim Control)
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).
0: Disabled
1: Enabled
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
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)
1: Torque Control
Sets the torque reference delay time in ms units.
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.
Sets the speed limit command method for the torque control method.
1: Analog Input - Limited by the output of the soft starter (b1-01
selection and active acceleration/deceleration and S-curve
settings).
2: Program Setting - Limited by d5-04 setting value.
Sets the speed limit during torque control as a percentage of the
maximum output frequency (E1-04).
This function is enabled when d5-03 is set to 2. Directions are as
follows.
+: run command direction
-: run command opposite direction
Sets the speed limit bias as a percentage of the maximum output
frequency (E1-04). Bias is given to the specified speed limit. It can
be used to adjust the margin for the speed limit.
Set the delay time from inputting the multi-function input
"speed/torque control change" (from On to OFF or OFF to ON)
until the control is actually changed. This function is enabled when
the multi-function input "speed/torque control change"
(H1-XX = 71) is set. While in the speed/torque control switching
timer, the analog inputs hold the value present when the
"speed/torque control change" is received.
For Normal Duty (ND) Rating: Setting Range=0.0 to 400.0.
