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
Speed during
command
".

Precautions at continuous operation to torque control mode
The following functions of the servo amplifier are not available during the
continuous operation to torque control mode.
Base circuit shut-off delay time function
Forced stop deceleration function
Vertical axis freefall prevention function
