6.8.3 Implementation of the Stop Category 0Bringing the motor to a standstill by immediately switching off the amplifier power supply(STOPMODE & ACTFAULT parameters set to 1). The switching sequence is precisely deter-mined by this circuit in order to avoid undesirable fault messages and servo amplifier failures.It is not possible to achieve a Category 0 shut-down with the servo amplifier alone, since hard-wiredelectromechanical components are compulsory for this type of disconnection.A brake that is built into the motor must have an additional electromechanical control circuit, as wellas the control through the SERVOSTAR 600, in order to meet Category 0.Usually a brake in a servo motor only has the function of a holding brake. To ensure an emergencystop function, the braking torque that is required must be checked. If the holding brake fulfills thedynamic requirements, it must be taken into acount that this application will cause increased wear.Circuit suggestion(with EMERGENCY STOP Category 0, control function with contactor relays)SERVOSTAR ® 601...620 Product Manual 29Danaher Motion 07/2007 Technical descriptionSERVOSTAR
