11.11.2.6 Limited speed

"Limited speeds" for the basic functions "Manual jog", "Homing" and "Positioning" can be set via the

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 ("Manual jog

", "Homing" or "Positioning") are

changed (limited).

• The response parameterised in C02716/3

(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" (C02715

) 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.
