6.3 Checking operation in Terminal mode
Warning
During the following procedure, the Drive will power the
motor and cause the shaft to rotate. Before starting, make
sure it will be safe for the motor to be run.
The following procedure applies when all the parameters are at their default
values, except for those adjusted as instructed earlier in this chapter.
1 Close the DRIVE ENABLE switch.
2 Check the display indicates rdY.
3 If another parameter has been selected on the display since the
AC supply was last connected, select parameter 0.10.
4 Close the RUN FORWARD switch. The display now shows 0 (the value of
0.10 Motor frequency).
5 Slowly advance the SPEED potentiometer to maximum. Check that
the motor speed and displayed motor frequency change accordingly.
If the direction is incorrect, open the
RUN FORWARD switch and close
the
RUN REVERSE switch. Two phases of the motor connections can
be reversed later (see Setting up the Drive for the machine). When the
RUN REVERSE switch is closed, a minus sign appears on the display to
indicate negative phase sequence at the output of the Drive.
6 Open the RUN FORWARD (or RUN REVERSE) switch. Check that the
motor decelerates to a stop and the display indicates
dEC
(decelerating) until the motor stops and the display returns to rdY.
7 If the Drive stops working and the display shows flashing text, this
indicates the Drive has tripped. The text indicates the cause of the
trip. Refer to Chapter 8 Diagnostics.
Press
to reset the Drive.
8 Disconnect the AC supply. (This completes bench-testing.)
