More Information about AMC10, AMC11 and AMC12

The 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.
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, motor-power, velocity, torque etc., can be monitored graphically and comparisons made with previously recorded curves. This facility greatly assists control and troubleshooting.
Servo Controllers AMC10, 11 and 12 are equipped with 6 digital inputs. These refer to 64 user-defined position and velocity references which are read into registers via the built-in RS232 interface. The AMC Controllers can also be velocity-controlled 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)
In the standard model, the preset values are executed in response to external signals, while an extended model enables the Controller itself to execute a sequential set of program instructions.
8 general purpose outputs can be configured, e.g. to provide a signal when the motor has reached a predefined position, or an error signal if an obstruction occurs and the motor cannot operate.
The Servo Controllers are very easy to program. For example, different velocity profiles can be set up by defining acceleration, deceleration (linear or s-curve) and velocity. The Controllers also include built-in programmable end-of-travel limits and a zero-point seek function.
As a signal from a feedback sensor to the digital control loop, the Controllers accept both a balanced and an unbalanced signal, for example from a standard 2-channel incremental encoder. The Controllers are prepared for master/slave interpolation control in 2 axes.

A new feature of these Controllers is the use of FLASH PROM, which enables the unit''s basic program to be upgraded at a later date if required.
All inputs and outputs are optically isolated and voltage-overload protected to provide a high degree of immunity to spurious noise signals. Similarly the Controllers are also protected against both thermal overload and short-circuits. The Controllers are designed and constructed to fulfil EMC requirements and are CE marked. The cabinets can be mounted in a 19" rack or mounted on a surface.

Programming and Use with MotoWare
Programming of the AC Servo Controllers is easily accomplished using JVL''s windows-based programming software, MotoWare. Controller programs are written in a very simple BASIC-like language, and several Controller programs can be opened and edited at the same time. Each Controller program is saved in a separate disk file. Windows show a complete overview of the various parameters. Multiple parameter sets can be saved under their own unique name and these can be retrieved, edited and sent to the Controller. The current set-up of a Controller can also be retrieved from the Controller and displayed on the screen or saved in the PC. During motor operation, the actual motor power, velocity, torque and deviation in position can be displayed graphically on the PC screen and printed out. This feature can be used for comparison with previously recorded curves and is extremely useful for checking that the system is operating optimally and for troubleshooting.
MotoWare is easily installed on a PC with Windows 95/98/ME/2000/XP or higher. Only 3 Mbyte of disk space is required for installation in addition to an available COM port for connection to the Controller. The screen above shows a velocity and power profile for an AC Servo in
