Mechanical Brake - Eaton M-Max Series User Manual

Mechanical Brake (Actuation)
The actuation of an external mechanical brake can be
implemented via one of the digital outputs (see "Digital
Outputs (P5)" on Page 78), if the value 26 (= External brake
actuated) is assigned:
Transistor output DO: control signal terminal 20 (DO–),
●
supply voltage control signal terminal 13 (DO+), maximum
48 Vdc/50 mA, Parameter 5.3
Relay RO1: N/O contact control signal terminal 22 (R13)
●
and 23 (R14), maximum 250 Vac/2A or 250 Vdc/0.4A,
Parameter P5.1
Relay RO2: changeover contact, control signal terminal
●
25 (R21), 24 (R22) and 26 (R24), maximum 250 Vac/2A or
250 Vdc/0.4A, Parameter P5.2
Braking, continued

Value/Range Description
— External brake, delay time opening
0.00–320.00s Condition: RUN (Start enable)
After the time set here has elapsed, the brake is actuated
(P5._ is opened)
— External brake, frequency threshold opening
0.00–P6.4 Hz Condition: RUN (Start enable)
If the frequency set here is exceeded, the brake is actuated
(P5._is opened)
— External brake, frequency threshold closing
0.00–P6.4 Hz If the frequency goes below the value set here, the brake is
actuated (P5._ is closed)
— External brake, frequency threshold REV closing
0.00–P6.4 Hz —
— External brake, current limit, opening
0.00–P7.2A Condition: RUN (Start enable)
On reaching the current value set here, the brake is actuated
(P5._ is opened)
