Error cause
• Switching to the stopper
control was requested to the
servo amplifier which is not
compatible with the
continuous operation to
torque control.
• During the speed-torque
control, the change value by
the torque limit value change
request (D(P).CHGT,
CHGT) or torque limit value
individual change request
(D(P).CHGT2, CHGT2)
exceeds the torque limit
value at speed-torque
control.
• The target position change
request (CHGP) was
executed for the axis which
was executing a servo
instruction which was not
compatible with target
position change.
