TM 5-3895-374-24-1 Configuration, special functions, settings Settings The  various  settings  accessible  are  listed  In  the  table  below  Depending  on  the  selections  made  during  configuration, inputs-outputs, or special functions, some parameters are not always available Example "Acceleration 2" only appears if a logic input has been assigned to "Switch to ramp 2". Parameters Values Factory setting Description Acceleration 0,2 to 990 s 5s Identical with Acc.   Acceleration time is automatically increased in the event of overtorque. Deceleration 0,2 to 990 s 10s Identical with dEc Deceleration time is auto- matically increased In the event of overbraking (display of code obr’  ). Low speed 0 to high speed 0 Identical with L5P- When low speed is at zero, the speed controller remains locked for as long as the reference is less than 1 Hz. High speed From low speed ATV-452 M 50 Hz Identical with H5P . to max frequency ATV-452 50 Hz ATV-452 N, S 60 Hz U/F adjustment N00 to N99 N00 Identical with UFr  Adjustment of the auto-adap- POO to P99 tation of theU/F ratio to the motor load If the FOO to F99 torque supplied by the motor at low speed Is LOO to L99 Inadequate, Increase the setting gradually. I thermal 0,45 to 1,05 In 0,9 In Moteur thermal protection Identical with itH No protection Adjustment of the electronic thermal protection Value In amps to be adjusted to the current value shown on the motor nameplate. Stability 0 to 100 0 Adjustment of motor stability Identical with StA In the event of instability, Increase the value of the parameter until correct operation Is obtained. Slip compensation 0 to 5 Hz According to rating    Adjust the slip compensation so as to obtain constant speed In permanent operating mode, whatever the motor load. Precaution  over compensation can lead to unstable operation. Preset speeds From low speed Low speed Preset speed levels In Hz. 1 to 6 to high speed 6 different levels possible. Reduce motor 100 % to 10 % 100 % Reduction of the voltage taken by the motor in voltage permanent operating mode 100 % full voltage applied 10 % 10 % of the voftage applied Reduce current limitation 150 % to 5 % 150% Current limitation reduction factor as % of the speed controller’s rated current Acceleration 2 0,2 to 990 s 5s Deceleration 2 0,2 to 990 s 10s (page 3-243)
