Usage conditions for the INTORQ spring-applied brake
❚ Degree of protection:
-
The brake is designed for operation under the environmental conditions that apply to IP54 protec-
tion. Because of the numerous possibilities of using the brake, it is still necessary to check the func-
tionality of all mechanical components under the corresponding operating conditions.
❚ Ambient temperature:
-
-20 °C to +40 °C (standard)
- -40 °C to +40 °C (Cold Climate Version: CCV)
4.1 Brake torque reduction
For basic module E, the brake torque can be reduced using the adjustment ring in the stator. The adjustment
ring can be unscrewed to the maximum protrusion of "h
Emax.
" ( 17 and 56).
NOTICE
Please observe that engagement times and disengagement times change depending on the
brake torque.
