6.2.11.3 Mechanical brake (actuation)
An external mechanical brake can be actuated via a digital output:
• Transistor output DO: control signal terminals 8 and 9, maximum
24 V DC, P-25 = 6
• Relay output K1: N/O control signal terminals 10 and 11,
maximum 250 V AC / 6 A or 30 V DC / 5 A, P18 = 6

0 Ramp, deceleration = dynamic braking
Deceleration time with the value set under P-04 (dec1).
If the energy that is fed back by the motor during dynamic braking is too
high, the deceleration time must be increased.
In devices with an internal braking transistor, the excess energy can be
dissipated with an external braking resistor (optional)
(￫ Section 6.2.11.2, „Regenerative braking“, page132).
1 Free coasting
After the start enable (FWD/REV) is switched off or the STOP button is
pressed (P-12 and P-15), the motor will coast uncontrolled.
2 Ramp, quick stop = dynamic braking
Deceleration time 2 with the value set under P-24 (dec2)
If the energy that is fed back by the motor during dynamic braking is too
high, the deceleration time must be increased.
In devices with an internal braking transistor, the excess energy can be
dissipated with an external braking resistor (optional).
