Control panel

The control panel consists of one LCD-display, one incremental shaft encoder, the upper
front housing and the foil keyboard. These parts can be exchanged separate. The
incremental shaft encoder regulates all parameters which are adjustable by pressing a key
and which are indicated in the LCD-display. In the speed display of the control panel the
error message is indicated if there should occur any trouble

1.8.2.4

Frequency converter

The frequency converter generates the drive signals for the asynchronous motor.
The converter leads the current generated by the motor during deceleration to a
heating resistor to reduce the current.
The frequency converter is connected with the power board by a serial interface.
There is a green LED on the converter which flashes when the frequency converter is
working correctly.
A defect of the converter will be indicated in the speed display as an error no.
