Maintenance and disposal
Read the general safety instructions before beginning work (see Chapter 2.7 "General safety
instructions").
7.1
Maintenance work
7.1.1 Refreshment of holding brake
The holding torques of the holding brakes used in the actuators are influenced by various factors,
e.g. oxidation of abraded particles, flattening of friction surfaces due to frequent application of the
brakes in the same position or air gap changes due to wear. This can lead to a tolerance in the
holding torque of - 50 % to + 100 %.
The specified holding torques apply under optimal conditions, without damaging influences. The
deterioration of the holding torque can be reduced by refreshing the brakes periodically.
For critical applications we recommend dimensioning for an adequately large holding torque to take
account of these factors. Our internal technical service would be glad to help you with the
appropriate dimensioning.
A maintenance interval of 4 weeks is recommended for common industrial applications.
For your dimensioning, observe the effective torques during running-in.
The permanent magnets of the rotor send a strong magnetic field,
which becomes active during the disassembling of the servo actuator.
Observe the general safety instructions (e.g. for pacemaker patients) for
working in strong magnetic fields.
The partial or complete disassembly of the actuator into its individual
parts for maintenance or repair work is not permissible.
In case of a malfunction or failure, please contact Customer Service.
