Table 7.16 T7, Vertical Braking 40% Duty Cycle
Horizontal braking: Duty cycle 10% and maximum 120 s repetition rates according the reference brake profile. Average power corresponds to 6%.
Vertical braking: Duty cycle 40% and maximum 120 s repetition rates according the reference brake profile. Average power corresponds to 27%.
Cable cross-section: Recommended min. value based upon PVC-insulated copper cable, 30
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature.
Thermal relay: Brake current setting of external thermal relay. All resistors have a built-in thermal relay switch N.C.
The IP54 is with 1,000 mm fixed unscreened cable. Vertical and horizontal mounting. Derating required by horizontal mounting.
IP21 & IP65 are with screw terminal for cable termination. Vertical and horizontal mounting. Derating required by horizontal mounting.
The IP20 is with bolt connection for cable termination. Floor mounting.
