Monitor torque bias command value
• Commanded torque bias value can be monitored
on the [FA-16] torque bias monitor.
• In the case of [Ad-11] = 07, the setting can be
changed on the [FA-16] monitor.
Parameter
• The torque command monitor (after calculation)
[dA-15] displays the value with torque bias added
to the present torque command.

Torque bias
setting
[Ad-12] -500.0~500.0(%) Adds a torque addition amount.
Torque bias
polarity selection
[Ad-13]
00 (Per sign)
Regardless of the operation direction,
torque will be added to the forward
direction, when the value is (+), and to
the reverse direction, when the the value
is (-).
01 (Follow the revolution
direction)
Changes the sign of the value and the
the direction of torque bias action into
the operation command.
