YASKAWA ELECTRIC TOEP C710616 41B YASKAWA AC Drive - A1000 Quick Start Guide
Description
0: Disabled. Drive starts from zero when the power is switched on.
1: Enabled. At power up, the drive starts the motor at the Hold frequency that
was saved.
Sets the bias added to the frequency reference when the Up 2 and Down 2
digital inputs are enabled (H1-oo = 75, 76).
0: Use selected accel/decel time.
1: Use accel/decel time 4 (C1-07 and C1-08).
0: Bias value is held if no input Up 2 or Down 2 is active.
1: When the Up 2 reference and Down 2 reference are both on or both off, the
applied bias becomes 0. The specified accel/decel times are used for
acceleration or deceleration.
The Up/Down 2 bias value is saved in d4-06 when the frequency reference is
not input by the digital operator. Set as a percentage of the maximum output
frequency.
Limits how much the frequency reference is allowed to change while an input
terminal set for Up 2 or Down 2 is enabled. If the frequency reference changes
for more than the set value, then the bias value is held and the drive accelerates
or decelerates to the frequency reference. Set as a percentage of the maximum
output frequency.
Sets the upper limit for the bias and the value that can be saved in d4-06. Set
as a percentage of the maximum output frequency.
Sets the lower limit for the bias and the value that can be saved in d4-06. Set
as a percentage of the maximum output frequency.
0: The lower limit is determined by d2-02 or an analog input.
1: The lower limit is determined by d2-02.
Description
0: Speed Control
1: Torque Control
Set to 0 when using a digital input to switch between Speed and Torque Control
(H1-oo = 71).
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.
Sets the speed limit during Torque Control as a percentage of the maximum
output frequency. Enabled when d5-03 = 2. A negative setting sets a limit in
the opposite direction of the Run command.
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.
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.
0: Disabled
1: Enabled
