Torque command setting method
During continuous operation to torque control mode, set time for the command
torque to increase from 0% to "
Pr.17
Torque limit setting value
" in "
Cd.151
Torque
time constant at continuous operation to torque control mode (Forward direction)
", and the
command torque to decrease from "
Pr.17
Torque limit setting value
" to 0% in
"
Cd.152
Torque time constant at continuous operation to torque control mode (Negative
direction)
". The value at continuous operation to torque control mode switching
request is valid for "
Cd.151
" and "
Cd.152
". The command torque during
continuous operation to torque control mode is limited with "
Pr.17 Torque limit
setting value
".
If torque exceeds torque limit setting value is commanded, a warning "Torque limit
value over" (warning code: 520) will occur, and the operation is controlled with
torque limit setting value.
Confirm the command torque to servo amplifier with "
Md.123
Torque during
command
".
During continuous operation to torque control mode, "Torque limit" ("
