7.2 Spindle Characteristics and Starting the Converter
Spindle Characteristics
All converters of BMR need an information about the basic data of the spindle, such as maximum
voltage, current, rotational speed, and many more. These are stored in so called "spindle
characteristics". A BMR spindle characteristic has 16 setpoints within the range of the rotational
speed. At every point data of voltage, current, load scaling, acceleration and deceleration ramp and
many more data can be defined and this for idle load as well as for full load. And there are in total 16
places for different characteristics. The spindle characteristics are the key for any spindle and give a
possibility to control the running behavior at every load condition.
In advance of start of a spindle first, it has to be ensured, that the proper characteristic is selected and
activated. This is generally the case if the device is delivered together with a spindle and the required
setup is done. If the converter and spindle are delivered separately, the proper spindle characteristic
has to be loaded into the converter first. This can be achieved with the free setup software SFU-
Terminal, easily.
In case of being unsure, characteristics for most common spindles are available at BMR.
The spindle characteristics can be defined either in the project file ( * .ps5 ) or via a setting in the
operating panel (-> 7.4 Setup ) . Furthermore, with the activation of the remote control interface is X4
( 6.3 / 6.6 ) a control via the digital inputs Bit1 ... Bit4 to X4 possible. The setting in the project file or
via the operator panel is then ineffective, however.
Spindle characteristics are created by BMR and can be loaded and managed using the SFU - Terminal .
Start and Stop
There are several possibilities for starting and stopping a spindle, due to many different requirements,
as follows below:
Generally, a STOP can be triggered by the source of START, only, with the exception of an Emergency
Stop, activated power stage pulse locking or any other safety function.
Start button at operating panel, Rotational speed with encoder potentiometer
Serial control with commands via RS232 / USB interface
Digital input in combination with an activated analogue input for control of rotational speed. In case of
not being activated, the rotational speed is setup with encoder potentiometer at the operating panel
or via serial commands.
Status display
The current status of the converter is displayed on the status LED display and with mounted operating
panel the status is displayed in plaintext on the LCD-display, additionally.
