Description
Set the contact signal (X42, X43)
based-torque bias amount using
Pr. 841 to Pr. 843.
Set the terminal 1-based torque
bias amount as desired in C16 to
C19. (forward rotation)
Set the terminal 1-based torque
bias amount as desired in C16 to
C19. (reverse rotation)
The terminal 1-based torque bias
amount can be set automatically in
C16 to C19, Pr. 846 according to
the load.
Without torque bias, rated torque
100%
Negative torque bias amount
(−400% to −1%)
Positive torque bias amount
(0% to 400%)
Without torque bias setting
Time until torque rises.
Same operation as when 0s is set.
Time for maintaining torque equiv-
alent to the torque bias amount.
Same operation as when 0s is set.
Set the voltage under balanced
load.
Same operation as when 0V is set.
Set the bias value of the torque
command.
Same as at a rise time (C16, C17).
Set the gain value of the torque
command.
Same as at a rise time (C18, C19).
Set the excitation ratio under no
load.
