Torque command setting method
During the 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 for
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 the
continuous operation to torque control mode is limited with "
Pr.17 Torque limit
setting value
".
If torque exceeding the torque limit setting value is commanded, the warning
"Torque limit value over" (warning code: 520) occurs, and the operation is
controlled with the torque limit setting value.
Confirm the command torque to servo amplifier with "
Md.123
Torque during
command
".
During the continuous operation to torque control mode, "Torque limit" ("
Md.108
Servo status
" (high-order buffer memory address): b13) does not turn ON. Confirm
the current torque value in "
Md.104
Motor current value
".
Buffer memory address (High-order)
