3.11. Brake option
Caution: The holding brake is used to completely immobilize the
servomotor under load. It is not designed to be used for repeated
dynamic braking ; dynamic braking must only be used in the case of an
emergency stop and with a limited occurance depending on the load
inertia and speed.
The standard brake power supply is 24 Vcc DC ± 10%.
Follow the polarity and the permissible voltage, and use shielded cables.
A 220 µF capacitor avoids untimely braking if the 24 V voltage is disturbed by the
external relay. Check the voltage value once this capacitor has been fitted. The RC
network (220 Ω, 0.1 µF) is needed to eliminate interference produced by the brake
coil.
Position the contactor in the DC circuit to reduce brake response times. Follow the
connection instructions taking the brake polarisation into account.
