The GRCF 1 is used for controlling frequency converters. Depending on the Controlling algo-rithm, the output frequency is
controlled from 0 through to the mains frequency.
In order to ensure controlled operation, the controller must have a power supply and must be enabled via digital input
DI1. If it is not enabled the process will no be regulated. The unit has an internal PID controller, whose parameters
(amplification factor, integral and differential time) can be configured either from the menu or via an external bus module.
the setpoint can be specified via the internal menu, an external analogue value or via an External bus module.
The Actual value is determined using a pressure sensor (4-20mA), a temperature sensor (KTY, GTF210) or a 0-10V signal.
The Digital inputs are designed as potential-free contacts that must be connnected to +24V.
as well as enable, digital inputs are also used to control the night limiter (D12) and setpoint switchover (D13).
