Chapter 12 Expansion Control
Speed limit value setting method
Acceleration/deceleration is performed based on a trapezoidal
acceleration/deceleration processing. Set acceleration/deceleration time toward
"
Pr.8
Speed limit value
" in "
Cd.148
Acceleration time at continuous operation to torque
control mode
" and "
Cd.149
Deceleration time at continuous operation to torque control
mode
". The value at continuous operation to torque control mode switching is valid
for "
Cd.148
" and "
Cd.149
".
"
Cd.147
Speed limit value at continuous operation to torque control mode
" is limited with
"
Pr.8
Speed limit value
". If the speed exceeding the speed limit value is commanded,
the warning "Speed limit value over" (warning code: 501) occurs, and the
operation is controlled with the speed limit value.
Confirm the command speed to servo amplifier with "
Md.122
