11.11.2.6 Limited speed
"Limited speeds" for the basic functions "
" and "
following parameters:
• The request "Limited speed 1 ... 4" is effected via the input LIM_dwControl, generally by the
control word of the safety module. If no safety module is available, the control word for the
input LIM_dwControl can also be generated by means of an inverter.
• By means of the input LIM_bActivateLimitedSpeed1 additionally the request of "Limited
speed 1" can be effected, e. g. via a digital input that is connected to this input.
• If a limited speed is requested and the current speed exceeds the limited speed:
• The setpoints of the active basic function ("
" or "
changed (limited).
• The response parameterised in
(Lenze setting: "No response") is activated.
• The error message "Speed has been limited" is entered into the logbook of the controller.
• A corresponding status is output via the LIM_dnState output.
• The display parameter "Limitation active" (
) is set to "1: Activated".
Process example: "Manual jog"
1. Manual jog in positive direction is active and the manual speed is greater than the "Limited
speed 1" set.
2. Via the control word of the safety module the "Limited speed 1" is requested.
3. The drive is decelerated to the "Limited speed 1" with the deceleration and S-ramp time set for
the "Limited speed 1".
4. At the same time, a corresponding status is output via the LIM_dnState output.
