2.2.6 Velocity Offset
If it is necessary you can adjust the analog velocity offset by providing 0 analog speed
reference and setting VO command for an automatic adjustment. A fine adjustment can be
done with successive steps via OV command.
REMARK: the adjustment of the digital velocity offset must not be used to adjust the analog
velocity offset and it is reserved to setup technicians. It can be made by providing 0 digital
speed reference (VE=0) and setting OC command. The opto Drive Enable must be high.
2.2.7 Personality Card Jumpers
WP (default: open): if closed, the EEPROM is write protected and SV command disabled
G1 (default: open) : if closed, connects TX- of serial link to 0V via pull-down resistor
G2
: if closed, gives priority to "opto" , if open gives priority to "keyboard"
G3 (default: open) : if closed, set 9600 Baud rate and basic address 1
G4 (default: open) : if closed, connects TX+ of serial link to 5V via pull-up resistor
G5 (default: open) : if closed, connects a 120
Ω
resistor between RX+ and RX- of serial link
CAUTION: it is recommended to close the WP jumper at the end of installation
and setup.
Fig. 2.4 - Personality Card
REMARK: personality card of DBM 03 has a software different from DBM 01 personality card.
To change DBM 01 with DBM 03:
1. Switch on DBM 03 with 230V mono-phase and replace the personality card with the old
DBM 01 personality card with G2 and G3 jumpers closed
2. Reset the drive with reset button on front panel
3. Wait 30 sec
4. Switch off the drive
5. Restore G2 and G3 as before the remotion
The personality card is now set to DBM 03 format. New parameters are: 1SO=1; 2SO=2;
CU=128; CV=128; DF=0; ES=16; ET=80; PW=91, RN=RX=12; PR=3 and VS=0 for 2 pole
resolver; PR=1 and VS=1 for 6 pole resolver; SE=1024 (if applicable).
Note:
- if the number of pulses per revolution has to be different from 1024, SE parameter
must be properly specified in the order
- after this setting the personality card cannot be used with DBM 01.
- with G2 and G3 closed DBM 03 does not work. The situation is as follows:
G2 open, G3 closed = keyboard priority, 9600 Baud, base address 1, password ON.
G2 and G3 closed = opto priority, reading of DBM 01 parameters (AC,AL/DL, AR/DR, BR, DE, IL,
IT, KI, KP, MR, MV, NP, OC, PC, RS, SA), password OFF.
