9 Start up and calibrations
9.1 First SPD start up
When the drive is started for the first time, of after giving the command “load default
parameters” the message
dEF
is shown on the display, to indicate the converter status.
At this point, the main parameters must be set for the motor connected to each axis. The basic
parameters are:
Pr29
Number of motor poles
N.
Pr32
Rated speed of the motor
rpm.
Pr33
Rated current of the motor
A
Pr34
Number of resolver poles
N.
Pr46
Phase-phase
motor
resistance
ohm
Pr47 Phase-phase
motor
inductance mH
After setting the motor parameters, the operator must give the data saving command, Pb99.15.
the drive shall calculate the correct values of Pr2, Pr3, Pr16, Pr17, Pr18, Pr19 and shall save
the parameter. The drive shall not calculate the values if during this procedure there is an
error. At this point the basic parameters cannot be modified. If you want to change one or
more parameters, set Pb94.3=1, the converter will show the alarm “dEF”, and after updating
the parameter value, you must save again by Pb99.15.
9.2
First commissioning of the drive
The steps to be followed carefully the first time the converter is used are given below.
1. Check that the connections have been implemented based on the provided diagrams
and instructions.
2. Make sure that the converter is shut off (pin 6 of the terminal board).
3. Power the converter on
4. the IdLE message appears on the screen
5. Set the analogue reference to 0 V (pin 25, 26 of the terminal board) and power the
converter on (24 V at pin 6 of the terminal board).
6. At this point the motor shaft should be stopped. Any change in the voltage of the
analogue reference should produce a proportional change in the speed of the motor. If
this does not happen, control the cabling.
The drive enabling bit (Pb41.5) can be set with a logical input only through the
picoPLC, or directly through serial or canbus
The converter comes with default values pre-defined that satisfy most applications. In the
default status the pico-PLC in the converter runs the program (described in
Appendix
) and the
following functions will be set at the input/output connectors:
