 MD36210: CTRLOUT_LIMIT[n] (maximum speed setpoint in %)
The max. permissible motor speed is specified in P1401:0 “Speed for max.
useful motor speed” of the SIMODRIVE 611 universal assigned to the machine
axis.
MD36210: CTRLOUT_LIMIT[n] corresponds to P1405:0 “Monitoring speed of
motor” of the SIMODRIVE 611 universal assigned to the machine axis.

 MD 36220: CTRLOUT_LIMIT_TIME[n] (delay time for speed setpoint
monitoring)
defines how long the speed setpoint may remain within the limits before the
speed setpoint monitoring responses.
Error response
 ALARM: “25060 Speed setpoint limiting”
and stopping the machine axis using a speed setpoint ramp whose
characteristic is set in
 MD36610: AX_EMERGENCY_STOP_TIME (time of brake ramp in case of
error conditions).
Error causes/remedy
 A control loop or drive error is present.
 Too high setpoint specifications (accelerations, velocities, reducing factors)
 Obstacle in work area (e.g. positioning on a working table)
=> Remove obstacle.
The speed setpoint consists of the speed setpoint of the position controller and
the feedforward control parameter (if feedforward control is active).
