Technical Description 1.1 General Information The transistor servo controller system series CVT is particularly designed for the triggering of equipments containing several DC-servo motors. It concerns plug-in type pulse width operate amplifiers of plug-in design (double Europe-card format). Up to six of these can be operated together with a central power supply within a cabinet frame. The amplifier operate in the quadrant modus, e.g. the connected motor in question can drive and brake in any direction of rotation, whereby pulse moment is available for a short time, being doubled compared with the permanent torque. The cabinet frame (assembly support) is suitable for the installation into 19"-cabinet (front installation) as well as for on back walls or bottoms of other cabinets of machines (back wall installation). 1.2 Special Features The equipments are provided with selected efficient and reliable components and assembled using an entirely new switching technique. The following advantages result therfrom for the user: - compact construction (storage inductor contained in assembly support). - no audible cycle noises from the motor or the inductors (cycle frequency 8.5 KHZ: frequency of the current ripple 17 KHZ!) - low self-warm up by using an especially low-loss out put. - low iron losses in motor and inductors (no iron losses on standstill) - very low minimum load and protective inductances. - parallel operation of several amplifiers on one motor is possible. - large range of operating voltage (60 to 240 volt) without the need to adjust the instrument. - no auxiliary voltage required (except for the fun from 150Aeff). - battery operation is possible (with brake energy refeeding). - direction-defined end switches with self-acting braking دریافت فایل جهت کپی مطلب از ctrl+A استفاده نمایید نماید |
