Mechanical brake (actuation)
The actuation of an external mechanical brake can be
implemented via one of the digital outputs (P5, see page 84), 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 V DC/
50 mA, Parameter 5.3.
• Relay RO1: N/O contact control signal terminal 22 (R13) and 23
(R14), maximum 250 V AC/2 A or 250 V DC/0.4 A,
Parameter P5.1.
• Relay RO2: changeover contact, control signal terminal 25
(R21), 24 (R22) and 26 (R24), maximum 250 V AC/2 A or
250 V DC/0.4 A, Parameter P5.2.

(P1.3)
P12.7 1448 - Open external brake, deceleration time 0.2
Setting range: 0.00 - 320.00 s
Condition: RUN (Start enable)
If the frequency set here is exceeded, the value 26 switches the
assigned digital output (P5…) and the brake is actuated
(ventilated).
P12.8 1449 - Open external brake, frequency limit value 1.50
Setting range: 0.00 - P6.4 Hz
Condition: RUN (Start enable)
After the time set here has elapsed, the value 26 is switched to the
assigned digital output (P5…) (brake actuated).
P12.9 1450 - Close external brake, frequency limit value 1.00
Setting range: 0.00 - P6.4 Hz
If the frequency goes below the value set here, the value 26
deactivates the assigned digital output (P5…). The brake closes
again.
P12.10 1451 - Close external brake, frequency limit value on reversing (REV) 1.50
Setting range: 0.00 - P6.4 Hz
P12.11 1452 - Open external brake, current limit value 0.00
Setting range: 0.00 - P7.2 A
Condition: RUN (Start enable)
On reaching the current value set here, the value 26 is switched to
the assigned digital output (P5…) (brake actuated).
