Mechanical installation 5 Important notes 5 Mechanical installation 5.1 Important notes Danger! Some of the motors mounted to the gearboxes are equipped with transport aids. They are only intended for the mounting/dismounting of the motor to the gearbox and must not be used for the entire geared motor! ¯ Only move the drive with means of transport or hoists that have sufficient load−bearing capacity. ¯ Ensure safe fixing. ¯ Avoid shocks! 5.
5 Mechanical installation Holding brake (option) Installation 5.3.1 Installation Important notes ¯ The mounting surface must be dimensioned for the design, weight and torque of the motor. ¯ The foot and flange faces must rest flat on the mounting surface. – Incorrect motor alignment reduces the service life of the roller bearings and transmission elements. Impacts on shafts can cause bearing damage. ¯ Do not exceed the permissible range of ambient operating temperature ( 19).
Mechanical installation 5 Holding brake (option) Installation The brakes operate according to the closed−circuit principle, i.e. the brake is closed in the deenergised state. The brakes for DC supply can be fed with a bridge−rectified DC voltage (bridge rectifier) or with a smoothed DC voltage. Information on the permissible voltage tolerance is provided in the respective motor catalogue.
5 Mechanical installation Holding brake (option) Permanent magnet holding brakes 5.4.1 Permanent magnet holding brakes These brakes are used as holding brakes and serve to hold the axes without backlash at standstill or in the deenergised state. When activating the brake, it must be ensured that the brake is released or engaged at zero speed to avoid unnecessary and rapid wear of the brake. When used solely as holding brakes, the brakes are virtually wear free on their friction surfaces. If the max.
Mechanical installation 5 Holding brake (option) Permanent magnet holding brakes Wear of permanent magnet brakes If applied as directed (application as holding brakes), the permanent magnet brakes of the servo motors are wear free and intended for long operating times. The wear on the friction lining is due to e.g. emergency stops. The table below describes the different reasons for wear and their impact on the components of the permanent magnet brakes.
5 Mechanical installation Holding brake (option) Spring−applied holding brakes 5.4.2 Spring−applied holding brakes These brakes are used as holding brakes and serve to hold the axes without backlash at standstill or in the deenergised state. For permissible operating speeds and characteristics, please see the respective valid motor catalogue. Emergency stops at higher speeds are possible, but high switching energy increases wear on the friction surfaces and the hub.

Before working on the power connections, always disconnect the drive component from the mains and wait until the motor is at standstill.
Electrical installation 6 Wiring according to EMC 6.2 Wiring according to EMC The EMC−compliant wiring of the motors is described in detail in the Operating Instructions for the Lenze controllers. ¯ Use of metal EMC cable glands with shield connection. ¯ Connect the shielding to the motor and to the device. 6.3 Plug connectors Stop! ¯ Tighten the coupling ring of the connector.

Observe permissible motor−encoder combinations during configuration.
Commissioning and operation 8 Important notes 8 Commissioning and operation 8.1 Important notes For trial run without output elements, lock the featherkey. Do not deactivate the protective devices, not even in a trial run. Check the correct operation of the brake before commissioning motors with brakes. 8.2 Before switching on Note! Before switch−on, you must ensure that the motor starts with the intended direction of rotation.
8 Commissioning and operation Functional test 8.3 Functional test ¯ Check all functions of the drive after commissioning: ¯ Direction of rotation of the motor – Direction of rotation in the disengaged state (see chapter "Electrical connection"). ¯ Torque behaviour and current consumption ¯ Function of the feedback system 8.4 During operation Stop! ¯ Fire hazard! Do not clean or spray motors with flammable detergents or solvents.
Maintenance/repair 9 Important notes 9 Maintenance/repair 9.1 Important notes Danger! Hazardous voltage on the power connections even when disconnected from mains: residual voltage >60 V! Before working on the power connections, always disconnect the drive component from the mains and wait until the motor is at standstill.
9 Maintenance/repair Maintenance operations Holding brake 9.2.3 Holding brake The brakes need to be checked on a regular basis to ensure safe and trouble−free operation. The necessary maintenance intervals primarily depend on the stress to which the brake is subjected in an application. When a maintenance interval is being calculated, all causes of wear must be taken into account (see notes "Wear on spring−applied brakes"). In the case of brakes which are subjected to low levels of stress, e.g.
Maintenance/repair 9 Maintenance operations Fan with dust protection filter 9.3.2 Fan with dust protection filter Dry−type filters are used for the motors. Dry dust should be removed completely by tapping. Note! The dust filter is mounted on the ventilation aggregate. Depending on the amount of dust, the filter must be cleaned and replaced in regular intervals! Soiled filters reduce the amount of cooling air significantly.
9 Maintenance/repair Maintenance operations Motor plug connection assignment 9.3.4 Motor plug connection assignment This motor−plug assignment is a rough selection of possible mechanical combinations. Note! When making your selection, the motor data and permissible currents of the cables according to the system cable system manual must be observed. Further information is provided in the system cables system manual at: www.Lenze.
