d4-05: Up/Dw2 Bias Mode Selection

No.

(Hex.)

Name

Description

Default

(Range)

d4-05

(02AC)

RUN

Up/Dw2 Bias Mode
Selection

Sets the function that saves the bias value to the drive when you open or close the two

Up2

Command, Dw2 Command [H1-xx = 65, 66]

. Set

d4-03 [Up/Dw2 Bias Step Frequency] = 0.00

before you set this parameter.

(0, 1)

0 : Hold@Up=Dw=0

When the two MFDI terminals set for

Up2 Command, Dw2 Command [H1-xx = 65, 66]

activate or deactivate, the

drive will hold the bias value.

1 : Reset@Up=Dw

When the two MFDI terminals set for

Up2 Command, Dw2 Command [H1-xx = 65, 66]

activate or deactivate, the

drive will reset the bias value to 0. The drive will use the acceleration and deceleration times set in

d4-04 [Up/

Dw2 Ramp Selection]

to accelerate and decelerate the motor to the selected output frequency.

■

d4-06: FRef Bias(Up/Dw2)

No.

(Hex.)

Name

Description

Default

(Range)

d4-06

(02AD)

FRef Bias(Up/Dw2)

Saves the bias value from the Up/Down 2 Command where the Maximum Output Frequency is
100%.

0.0%

(-99.9 - +100.0%)

The Up/Down 2 function setting changes the function of

d4-06

Note:

When the keypad sets the frequency reference, you do not usually use parameter

d4-06

•

When

d4-01 = 0 [FRef Hold Selection = Disabled]

and a source other than the keypad sets the frequency

reference, the drive adds the value set in

d4-06

to the frequency reference. If the value set in

d4-06

is a negative

number, the drive will subtract it from frequency reference.

•

When

d4-01 = 1 [Enabled]

and a source other than the keypad sets the frequency reference, the drive will store

the bias value adjusted with the Up/Down 2 command in

d4-06

5 seconds after you release the Up/Down 2

command. The drive adds or subtracts the value set in

d4-06

to the frequency reference.

Conditions that Reset or Disable d4-06

The drive resets and disables the bias value in these conditions:

•

d4-01 = 0

and the Run command was cleared.

•

H1-xx = 65, 66 [MFDI Function Select = Up2 Command, Dw2 Command]

is not set.

•

The frequency reference source was changed.
This includes switching LOCAL/REMOTE and multi-step speed reference.

•

A digital input changed the frequency reference value.

•

d4-03 [Up/Dw2 Bias Step Frequency] = 0

and

d4-05 = 1 [Up/Dw2 Bias Mode Selection = Reset@Up=

DwReset when Neither / Both Closed]

, and the two MFDI terminals set for

H1-xx = 65/66 [Up2 Command/Dw2

Command]

are activated or deactivated.

•

The value of

E1-04 [Max Output Frequency]

was changed.

d4-07: Analog FRef Fluctuate Limit

No.

(Hex.)

Name

Description

Default

(Range)

d4-07

(02AE)

RUN

Analog FRef Fluctuate
Limit

If the frequency reference changes for more than the level set to this parameter, then the bias
value will be held. The value is set as a percentage of the Maximum Output Frequency.

1.0%

(0.1 - 100.0%)

Handles frequency reference changes while

H1-xx = 65, 66 [Up2 Command, Dw2 Command]

is activated. When

the frequency reference changes for more than the level set in

d4-07

, the drive will hold the bias value, and the

drive will accelerate or decelerate to the frequency reference. When the drive is at the frequency reference, it
releases the bias hold and the bias follows the Up/Down 2 input commands.

This parameter is applicable only when an analog or pulse input sets the frequency reference.
