Siemens SIDOOR ATD4 W Series - Slow Driving Curve Profile

4.1.12 Slow driving curve pro󹪝le
The SIDOOR ATD4xxW controllers support a parameterizable, speed-reduced speed pro󹪝le (slow
pro󹪝le) to which a changeover can be carried out 󹪞exibly.
Parameter assignment
You can con󹪝gure the following parameters equally via the parameter interface, the service tool
and the terminal.

Drive order for pro󹪝le switching
To switch to the slow pro󹪝le, the DCMD expansion bit "slow" (see Table A-17 DCMD expansion
bits (Page 320)) must be set. In combination with an applicable DCMD drive order (see Table
A-16 DCMD signal (Page 319)), the drive switches to the slow pro󹪝le.
Switching pro󹪝les
The drive switches over to the slow pro󹪝le when the corresponding drive order with expansion
bit is active and the controller is in normal mode. The slow pro󹪝le can be activated or deactivated
dynamically during travel. The activation of the slow pro󹪝le brakes the drive automatically to the
speed of the Slow pro󹪝le in accordance with the parameterized reversal ramp. Minimally,
however, with 500 mm/s². When the Slow pro󹪝le is deactivated, the drive accelerates with
1500 mm/s² to the speci󹪝ed end speed.
Independent values, which are not in󹪞uenced by the speed parameters described here, apply to
the speed in the initial or learn run mode.
Drive response
When the slow pro󹪝le is active, all drive functions are supported without restriction.
