29 General project planning information Circuit breaker and protective equipment 4 4. Circuit breaker and protective equipment 4..1 Preventive measures Synchronous servomotors must be protected against overload and short circuit. Install the motors with sufficient space for air to cool them. The surface temperature may be in excess of 100 C during operation in accordance with thermal classification F. Therefore, measures to prevent inadvertent contact are essential. The motors are equipped with temperature detection to protect the motor winding against overheating. The temperature is measured by temperature sensors KTY 84 to 130 installed as standard, or, for sizes 71 to 11 by optionally available /TF temperature sensors. The correct model must be activated in the servo inverter to enable thermal motor protection (I t, effective current monitoring). For information on the procedure, refer to the documentation of the servo inverter EC measures SEW EURODRIVE synchronous servomotors are intended as components for installation in machinery and systems. The designer of the machine or system is responsible for complying with EC Directive 004/108/EC. Routing brake cables Brake and power cables may only be routed together if either the brake cable or the power cable is shielded. We recommend that you use prefabricated cables ( 341). Notes on encoder connection Observe the following notes when connecting an encoder: Use only a shielded cable with twisted pair conductors. Connect the shield to the PE potential on both ends over a large surface area. Thermal motor protection The cables can only be routed together if either the KTY cable or the power cable is shielded. We recommend that you use prefabricated cables ( 341). Catalog CP40 CP11, CPZ71 CPZ100 9

40 Project planning echanical and electrical characteristics.6.1 Speed classes, rated speeds Speed classes (rated speeds) of synchronous servomotors: 000 rpm 3000 rpm 400 rpm 6000 rpm As synchronous servomotors operate as controlled drives, it is necessary to consider the inertia ratio between the load and the motor. This ratio is a decisive factor in determining the quality of closed-loop control. The inertia ratio should not exceed the values listed in the table below. Reduction of the inertia ratio using the motor speed or the selected gear unit reduction ratio offers hardly any advantage with respect to closed-loop control starting at the value J ext / J ot < 8. Backlash and elasticity negatively influence the possible dynamic response of the driveline and must be kept to a minimum. As a result, the maximum speed should be selected such that the following criteria are met: Driveline Control characteristics Inertia ratio J ext / / J ot Forged gear rack, reduced backlash gear unit Toothed belt, reduced backlash gear unit Toothed belt, standard gear unit Low backlash and low elasticity drive J ext / J ot < 1 Common servo applications J ext / J ot < 1 Standard applications, couplings with torque buffer (elasticity) J ext / J ot < Catalog CP40 CP11, CPZ71 CPZ100

These motors are the optimum choice in very dynamic applications. For high accelerations and accelerations in the millisecond range, the synchronous servomotor is usually the technically and economically best solution. Additional flywheel mass The rotor of the CPZ synchronous servomotor is equipped with an additional flywheel mass. This additional flywheel mass allows for handling large external masses. Cogging The motors produce small torque ripple due to the servo drive design. This torque ripple is corrected by the inverter. 4 Catalog CP40 CP11, CPZ71 CPZ100
