Range Description
Set the contact signal (X42, X43) based-
0
torque bias amount using Pr.841 to Pr.843.
Set the terminal 1-based torque bias amount
1
as desired in C16 to C19. (forward rotation)
Set the terminal 1-based torque bias amount
2
as desired in C16 to C19. (reverse rotation)
The terminal 1-based torque bias amount
3 can be set automatically in C16 to C19,
Pr.846 according to the load.

You can use the mechanical resonance
speed to make this setting to reduce the
0 to 60 response level of the mechanical
resonance frequency band, avoiding
mechanical resonance.
