AC Servo Controllers AMC10, AMC11 and AMC12 AMC10, 11 and 12 are a series of AC Servo Controllers which can be used to control both AC and step motors rated up to 1kW. The Controllers are based on a 16-bit microprocessor and 32bit signal processor, and are characterised by great flexibility for a wide range of control applications. The Controllers can be controlled directly via the built-in RS232/RS485 interface, or indirectly via 6 digital inputs. In addition, models can be supplied with a built-in Fieldbus interface. The Controllers can be directly connected to PLCs equipped with controller modules. Up to 255 units can be connected to the same RS232 bus, and thus a PC or PLC can function as controller for a multi-axis system. Using JVL´s programming software, MotoWare, motorpower, velocity, torque etc., can be monitored graphically and comparisons made with previously recorded curves. This facility greatly assists control and troubleshooting. • Compact and programmable • EMC tested.

Description (continued) Servo Controllers AMC10, 11 and 12 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 interface or a Fieldbus interface. The AMC Controllers can also be velocitycontrolled via an analogue input of +/10V. In addition, the Controllers can be configured as a step motor system using step-pulse and direction signals. A special mode of operation enables electronic gearing through a selectable keyed-in ratio (from 0.001 to 9999.999) with a resolution of 1 to 1000. In the...

Modes of Operation Step-pulse Mode In this mode the Controller operates 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. The encoder enables monitoring and adjustment during motor operation, a feature which 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. Step-pulse mode Power Running Error Current T>80 C IO1 IO2 IO3 IO4 Pulse signal Out Error IO5...
