840 Torque bias selection

The torque bias function is designed to quicken the rise of torque at a motor start. You

can set the then output torque using the parameters or analog signals.

9999

0: 3 internal parameters, 1 to 3: External analog input, 9999

841 Torque bias 1

Set the torque bias values when you chose internal parameter-based torque bias

selection. Assign X42 (torque bias selection 1) and X43 (torque bias selection 2) to the

842 Torque bias 2

input terminals.

9999

600 to 1400%

843 Torque bias 3

1) Pr. 841 when X42 is on and X43 is off, 2) Pr. 842 when X42 is off and X43 is on, 3)

Torque bias operation

Set the time until the set torque of the torque bias amount is generated.

846 Torque bias balance

Set the torque balance with the balance weight.

0 to 10V, 9999

847 Fall-time torque bias

When you set 1 or 2 in Pr. 840, set the bias value of the torque bias at the time of fall

from the load input from the No. 3 terminal.

9999

No. 3 bias

0 to 400%, 9999

848 Fall-time torque bias

When you set 1 or 2 in Pr. 840, set the gain value of the torque bias at the time of fall

from the load input from the No. 3 terminal.

9999

No. 3 gain

0 to 400%, 9999

849 Analog input off set

When speed command by analog input is set, create the range where the motor

remains stop to prevent malfunction at

very low speed.

851 Number of PLG

Set the number of pulses of the PLG.

2048

pulses

0 to 4096

Set the rotation direction of the PLG.

862 Notch filter frequency

You can use the machine resonance speed to make this setting to reduce the response

level of the machine resonance frequency band, avoiding machine resonance.

863 Notch filter depth

Set the depth at which the gain of the machine resonance frequency set in Pr. 862 is

lowered.

864 Torque detection

You can make setting to output a signal if the motor torque exceeds the predetermined

value.

865 Low speed detection

You can make setting to output a signal if the speed has fallen to or below the preset

low speed.

866 Torque monitoring

Set the reference for the motor torque or load meter torque monitoring output (DA1 or

other analog output).
