CHAPTER 4 - START-UP AND
ADJUSTMENT OF THE DRIVE
4.1 Introduction
For the procedures of start-up and adjustment of BHL-D (see chapter 7), both the keyboard
and the serial interface can be used. The following paragraphs outline procedures that can be
carried out using the keyboard.
Afterwards, signals available on the terminal boards and some possible connections will be
described. In the end basic procedures for the start-up and the adjustment of the convertor
will be outlined.
4.2 How to use the keyboard
The alphanumerical keyboard consists of 8 membrane keys and of an alphanumerical display
with two lines of 16 characters each. It can be assembled on the front of the drive or
connected with a flat cable in the appropriate connector.
The keyboard management is arranged in three visualizstion windows, each one with a
different function: the first window, the window of References, is shown when the unit is
switched on. The second window shown is for Parameters and the third one contains Flags.
To move from one window to another use MODE key.
The first window shows all references of speed (W_ref), position (P_ref), and current (I_ref),
all in the first line. The second line always visualizes the actual speed (Speed). To see the
three references use UP (▲) and DOWN (▼) keys . To modify them press ENTER key and
the cursor will start blinking: use the arrow keys UP and DOWN to increase or decrease the
set value.
All keys have a "hold" function: this means that, if a key is pressed for a Iong time, the
increasing or decreasing of the value that you are setting becomes faster . By pressing CLR
key , the set value will be canceled.
