CMESA SERVO-DRIVES & MOTION CONTROL SERVO CONTROLLER SERIES Power Supply SMN/W Operating Manual

General Safety Information This information sheet is an addition to the manual and has to be read carefully. These electronic units are units to be used in industrial electric power plants. These units have dangerous, voltage-carrying bare parts or moving or rotating parts during operation. These parts may lead to serious health problems or material damages in case of inadmissible removing (for example) of the required covers, inproper application, wrong installation or operation or insufficient maintenance. The persons that are responsable for the safety of the plant have to grant that ■ only...

2 Principles of Operation The servo modules are designed for rack systems in 6HE sizes . Their application range can be extended by using different options. In order to grant the high reliability of the system and the security of the personal, the following regulations have to be considered: VDE 0100, VDE 0160, part 1 and 2 in relation with VDE 0660, part 5 as well as VDE 0113. For limit values, please look the specifications. Inadmissible working conditions or wrong application of the amplifiers should be avoided. Mounting position: Cooling: Electronic supply: Mains AC supply: front connector...

3.2 Functional Description Speed controller fast PI controller, for exact control of motor speed by means of comparison of Speed demand and tacho voltage, produces current demand max. ± 10 V Current controller fast PI controller for exact control of armature current enclosing the whole range of output voltage, produces control voltage for PWM Pulse Width Modulator (PWM) produces logic control signals for the power stage by special modulation technics Power stage MOS-FET, IGBT or bipolar power stage in bridge circuit for low-loss power control Armature current measuring fast measurement of the...

3.3.2 Integral Off Function By applying 0 V on X7 / PIN 10 the speed controller will be switched over from PI to P-mode. Thus a higher stability and a lower drift can be reached under certain conditions. 3.3.3 Second Input (Speed Command) Two equivalent speed demand inputs are available on the amplifier. The weighting can be influenced by changing R111 input 1 and R112 input 2. With the two inputs a big speed range can be easy adjusted. Speed is relatively low, for example: Input 1 10 V = 3000 rpm ⇒ high speed operation Input 2 10 V = 300 rpm ⇒ low speed operation 3.3.4 Armature Current Monitor...

Further option boards are available. The limit switches become inactive when connecting 0 V. If the input remains open, the negative and/or positive speed demand will be blocked. The logic level is fixed by factory and cannot be changed, standard: negative logic. On operation of the limit switch the motor stops in the given direction with a maximum adjusted IAmax. Caution: do not connect voltage on the limit switch inputs! With certain motor types it becomes necessary to limit the armature current by high speed. By means of the armature voltage measuring and a plug module (X1) corresponding to...

Ramp time constant in s/V Pot. R8 A jump of set value of 0 V to 10 V will be transformed in a 0,03 s long ramp. Asymmetrical relations of positive and negative ramp can be set by using R3 (positive ramp) and/or R4 (negative ramp) according to the above table. The values are valid for Options without C2 fur standard placement of R111 and R112 on the logic board. The ramp time can be prolongated by using C2. This option is for speed control without tacho - generator. The motor speed can be set by potentiometer R11. By extending R111 set value input 1 or R112 set value input 2 (both on the logic...

• Plug the Option board only in powerless mode ! The Pot. R8 and R11 are oriented to connector X7 andX8. • Select operating mode : Option - Board for SMVE, SMVEE for SMVEN

If the monitoring exceeds one signal, it is possible to plug another PLS-module on the X3 option connector, this allows the monitoring of two signals at the same time. With the front switch it is possible to reset a fault without switching off the supply voltage. Further options on demand.

4 Power Supply - Mains Transformer The power supply of the SMVE/N control modules is always assured by a 1- or 3-phase transformer with separated primary and secondary winding. The star point of the transformer will not be connected. The transformers delivered by us correspond to VDE 0550 regulations and are equipped with IP00 protection. They can be applicated in switch cabinets with the same power with surrounding temperatures up to ϑu = + 40°C. Standard winding of the transformers is according to vector group YY0 (the star point cannot be connected). 4.1 SMVE/E Racks In multi-unit-systems...
