VT-MACAS-500-10/V0/  VT-MACAS 模拟定位模块

通过该控制器模块，可以将简单的位置或速度控制与博世力士乐伺服缸与模拟位置测量系统(电位器)相连接。由于整个信号处理是模拟的，并且该模块仅配备了设置控制所需的功能，因此驱动器的成本可以保持较低。另外还有一个特殊性，模块内部可以切换到速度控制(前板)，电压接口和电流接口各提供一个版本，参考命令和实际值。
位置控制
将位置的命令值与实际值进行比较，并将偏差转发给阀放大器。当输入信号发生突变时，系统将以最大的动态性作出反应。负载加速或制动的时间要么受可用功率限制，要么受系统增益限制。以斜坡函数作为输入值，负载以恒定速度移动。

VT-MACAS-500-10/V0/I

By means of this controller module, simple position or velocity controls can be represented in connection with Bosch Rexroth servo cylinders with analog position measurement systems (potentiometer). As the entire signal processing is analog and the module is only equipped with the necessary features for the set-up of controls, the costs for the drive can be kept low. There is moreover the particularity that the module can be internally switched to velocity control (front plate) and one version is in each case offered for voltage interface and current interface, referring to the command and actual values.
Position control
Command and actual value of the position are compared and the deviation is forwarded to the valve amplifier. In case of an abrupt change of the input signal, the system will react with maximum dynamics. The times for accelerating or braking a load are either limited by the available power or the system gain. With a ramp function as input value, the load is moved with a constant velocity.

– The distance to aerial lines, radios and radar systems must be sufficient (> 1 m).
– Do not lay solenoid and signal lines near power cables.
– For signal lines and solenoid conductors, we recommend using shielded cables.
The cable shield must be connected to the control cabinet extensively and as short as possible.
– The valve solenoid must not be connected to free-wheeling diodes or other protection circuits.

– Suitable for controlling valves with installed electronics for position and velocity control
– Design: Module for snapping onto carrier rails
– Enable input
– Cable break detection for actual value cable
– Interfaces short-circuit-proof
– Test points on front plate
– Compensation step that can be switched off
– Position: PT1 control
– Velocity control possible in connection with tachometer (speed indicator): PI control
– Area adjustment cylinder
