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".
