7.2 Starting of the Converter and Power Stage Pulse Lock
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.
Start and Stop
There are different possibilities for starting and stopping SFU0303, due to many different
requirements, as follows below:
Generally, a STOP can be triggered by the source of START, with the exception of an Emergency
Stop, activated Intermediate voltage lock or any other safety function.
- Start button at operating panel, Rotational speed with encoder potentiometer
- Pure serial control with commands via USB / RS232 / RS485 / Profibus 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 poti on operating
panel or via serial commands.
Power Stage Pulse Lock
Precondition for proper starting is a released power stage pulse lock (Bridge X2.2 – X2.10), as well as
a proper characteristic for the connected spindle.
The converter of the 0303 series are equipped with an safety power stage pulse locking circuit which
has to be wired properly for operation. For activating the power stage a voltage with carrying a high
signal should be applied to digital input 2 / PIN2. The voltage can be fed from PIN10. So, easy as
possible simply a bridge between PIN2 and PIN10 will do this. The feedback signal about the status is
displayed on the operating panel, if equipped, on LED6 and on relay output 6 at connector X3.
Attention! Without this connection the converter cannot be started.
The power stage pulse lock is realized according the requirements of EN954-1 Category 3 for safe
stop of drives. (-> Chap 8.7) +24V: Power Stage released 0V: Power Stage locked.
Status
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.
