Testing the System
9.1
General
This section describes some simple test procedures for some parts of the Q-Drive
systems. These do not comprise a full system test, but may be useful to verify the basic
operation of the system, the motor and the encoder.
All these tests require the use of a personal computer with a serial port, preferably
RS422. Most test can be carried out on the PC but additional test equipment may be
necessary. The test are given in a logical sequence i.e. it is not possible to check the
resolver interface if the Serial communications do not work and the encoder simulator
will not generate signals until the resolver interface works.
9.2
Serial port
The serial port only transmits data after it receives a request from the QDRIVE.EXE
software, this means that it is necessary to connect a personal computer (PC) and run
the QDRIVE.EXE software in order to test the serial port. Ensure that the program is
requesting data from the axis number which the drive is set to, i.e. if the drive is set to
address 7 then the program should request data from axis 7. If the serial
communications are working correctly then the program will display the line:
Press the <F2> key this should make the 7 segment display on the front of the drive
flash. If there is no response from the drive then check the connections between the PC
and the drive. If there is still no response from the drive then check the serial data
signals using a data analyser or an oscilloscope, to verify whether the drive is actually
responding to the characters being sent to it. The serial data analyser should be set for
9600 Baud, 8 data bits, no parity and 1 stop bit.
9.3
Resolver Interface
Connect a resolver to the drive and monitor the "Resolver Position" read out on page
6 of the
QDRIVE.EXE
produce an updating display every time the resolver shaft is moved then the drive will
need to be returned to Quin Systems Ltd. for repair.
