Chapter 12 Expansion Control
Set time that reaches "
Pr.17 Torque limit setting value" from 0% in " Cd.144 Torque
time constant at torque control mode (Forward direction)" and time that decreases 0%
from "
Pr.17 Torque limit setting value" in " Cd.145 Torque time constant at torque control
mode (Negative direction)
". The value at torque control mode switching request is
valid for "
Cd.144 " and " Cd.145 ".
The command torque during torque control mode is limited with "
Pr.17 Torque limit
setting value
". If the torque exceeds torque limit setting value is set, a warning
"Torque limit value over" (warning code: 520) will occur, the operation is controlled
with torque limit setting value.
Confirm the command torque to servo amplifier with "
Md.123 Torque during
command".
