Speed control
9.2.1
Overview
The speed-controlled operation (profile velocity mode) comprises the following
subfunctions:
ƒ
Setpoint generation by ramp generator
ƒ
Speed detection via angle encoder by differentiation
ƒ
Speed control with appropriate input and output signals
ƒ
Limitation of torque setpoint (
torque_demand_value
)
ƒ
Monitoring of actual speed (
velocity_actual_value
) with window
function/threshold
The meaning of the parameters
profile_acceleration
,
profile_deceleration
and
quick_stop
is described in chapter ”Positioning”.
