LD0025-04GB Date: 18-11-04 AC Servo Motor Controllers AMC20, AMC21 and AMC22 AMC20, 21 and 22 are a series of AC Servo Controllers which can be used to control AC motors rated up to 3kW. The Controllers are based on a 16-bit microprocessor and 32- bit signal processor, and are characterised by great flexibility for a wide range of control applications. The AMC20/22 controllers can be controlled directly via the built-in RS232/RS485 interface, or indirectly via 6 digital inputs. The Controllers can be directly connected to PLCs equipped with controller modules. They are specially developed also for use with linear motors, with or without hall sensor. Up to 255 units can be connected to the same RS232/485 bus, and thus a PC or PLC can function as the controller for a multi-axis system. Using JVL´s programming software, MotoWare32, parameters such as motor power, velocity, torque, etc., can be monitored graphically. The AMC 20/22 servo controllers are developed and manufactured in Denmark. • Built-in mains noise filter • EMC tested.

Description (continued) Servo Controllers AMC20, 21 and 22 are equipped with 11 digital inputs. 6 of these refer to 64 user-defined position and velocity references which are read into registers via the built-in RS232/ 485 interface. The AMC Controllers can also be velocity-controlled via an analogue input of +/- 10V. In addition, the Controllers can be controlled as a step motor system using step-pulse and direction signals. A special mode of operation enables electronic gearing at a selectable, keyed-in ratio (from 0.001 to 9999.999) with a resolution of 1 to 1000. In the standard model,...

Modes of Operation Step-pulse Mode In this mode the Controller functions as in a step motor system. The motor moves one step each time a voltage pulse is applied to the step-pulse input. Velocity, acceleration and deceleration are determined by the external frequency. Use of an encoder enables monitoring and adjustment during motor operation — a feature that is not possible with a standard step motor system. In addition, the AMC Controllers also provide a facility for electronic gearing at a keyed-in ratio. Positioning Mode In this mode the Controller positions the motor via commands sent...
