Brake motors must always have a drain line. The brake-release pressure is the difference between the pressure in the brake line and the pressure
in the drain line.
4)
For the supply of motors with holding torques higher than those stated, please contact the Danfoss sales organization.
For maximum permissible combination of flow and pressure, see function diagram for actual motor.
