1) Intermittent operation: the permissible values may occur for maximum 10% of every minute.
2) Peak load: The permissible values may occur for maximum 1% of every minute.
3) 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.
