9. The Drive is supplied configured for start and stop control by a RUN
contact. For start and stop control via serial communications, send a
write-command to set parameter 8.21 Digital input 1 destination
selector at 00.00. This ensures digital input 1 cannot continue to
control the motor. Alternatively, digital input 1 can be assigned to
another parameter in order perform a different function.
10. Send a write-command to set parameter 6.34 Sequencing bit RUN
at 1.
If mechanical resonances occur when the motor is running, see
Testing the system in Specifying shaft stiffness and load inertia on
page 94.
11. Send a write-command to set parameter 1.21 Preset reference 1 at
a suitable value of speed in RPM (e.g. 100). The motor then
accelerates to the entered value.
12. Send a read-command to check that parameter 10.02 Drive running
indicator is set at 1.
13. Send a read-command to check that the value of parameter 3.02
{0.05} Speed feedback (e.g. 100.0) is the same as the value of
parameter 1.21 (e.g. 100).
14. Send a write-command to change parameter 1.21 Preset reference
1 to a negative value (.eg. –80). The motor decelerates to rest then
accelerates to the speed reference in the reverse direction.
15. Send a read-command to check that the value of parameter 3.02
{0.05} Speed feedback (eg. –80) is the same as the value of
parameter 1.21 Preset reference 1 (eg. –80.0).
16. Send a write-command to set parameter 6.34 Sequencing bit RUN
at 0. The motor decelerates to rest.
17. When the motor has stopped, send a read-command to check that
parameter 10.03 At zero speed indicator is set at 1.
18. Open the Hardware enable contact or send a write-command to set
parameter 6.15 Drive enable at 0.
If a Hardware enable contact is being used, it can be left
continuously closed. In this case, to disable the Drive, set 6.15 Drive
enable at 0. To subsequently re-enable the Drive, open then re-close
the contact or set parameter 6.15 at 1.
19. Send a read-command to check that parameter 8.09 {0.01}
Hardware enable status is set at 0.
20. Perform the following, as appropriate:
Version _AN
Initiate the save operation by setting parameter XX.00 at 1000.
Execute the operation by setting parameter 10.38 at 100.
Version _SL
Version _AN (if required)
Ensure the Drive is disabled by checking that the Hardware enable
contact is open or that parameter 6.15 is set at 0, then perform either
of the following:
•
Initiate the store operation by setting parameter 0.50 at 2 (Prog).
Execute the operation by setting parameter 10.38 at 100.
•
Set 11.67 Flash update enable at 1.
21. To use the stored values after the next power-up, ensure parameter
0.50 is set at boot2 (4). If you have to change the setting,
immediately afterwards execute the operation, as described in step
20.
Summary
The procedure has shown the following (for either version controlled by
serial communications):
• When the Drive is inhibited (disabled) (i.e. Hardware enable
contact is open or parameter 6.15 Drive enable is set at 0), 8.09
{0.01} Hardware enable status is set at 0.
•
When the Drive is enabled (i.e. Hardware enable contact is
closed and 6.15 Drive enable is set at 1) but not running, 8.09 {0.01}
Hardware enable status is set at 1.
•
To start the motor, set 6.34 Sequencing bit RUN at 1.
• When 6.34 Sequencing bit RUN is set at 1 and the motor is
stationary, accelerating, decelerating or running at a constant speed,
10.02 Drive running indicator is set at 1.
•
When the motor is running in the reverse direction, the speed
value is negative.
•
To stop the motor, set 6.34 Sequencing bit RUN at 0.
Alarms and trips
Alarms and trips are described in Appendix B Diagnostics on page 84.
When the Drive is running, periodically send read-commands to check
the values of the following parameters:
10.01 Drive healthy indicator
10.19 Alarm indicator
If 10.01 becomes set at 0, this indicates that the Drive has tripped (the
motor will no longer be controlled and will be allowed to coast).
Parameter 10.20 is set at the value of the trip code.
If 10.19 becomes set at 1, this indicates that one of the following alarms
has occurred:
10.12 Braking-resistor overload alarm indicator
10.17 Motor overload alarm indicator
10.18 Heatsink temperature alarm indicator
To clear a trip, correct or remove the cause of the trip, then reset the
Drive by sending a write-command to set parameter 10.38 at 100.
