5 Getting Started
5.1 Electrical power connections
Before continuing, ensure the Drive has been connected in accordance
with the instructions in Chapter 2 Installing the Drive in the Installation
Guide, including correct use of the ground bracket.
When following the instructions in this chapter, it is your responsibility to
connect and disconnect the AC supply as required.
The AC supply must be connected to the Drive with
appropriate fuses or protection, as described in the
Installation Guide.
Adjustment of parameter values must be performed
only by suitably trained or experienced personnel.
Incorrect values could be hazardous.
For product familiarisation, it is recommended that you
make only the adjustments stated in the following
procedures. If you do adjust any other parameter(s),
first note the original value(s).
Failure to restore the Drive to the default state when
instructed in this chapter may result in inadequate
thermal protection and unstable control of the motor.
5.2 Procedure for Keypad mode
Version: _AN
1.
Ensure the signal connections for Keypad mode have been made
(Figure 2–3).
2. Perform the procedure in Specifying shaft stiffness and load inertia
on page 94. Failure to perform this procedure will omit essential
steps. It may also result in unstable control of the motor and the
Drive tripping.
3. Set parameter 0.30 Reference selector at 4.
4. Ensure parameter 0.34 Keypad reference is set at 0.
5. Press at the same time...
The value of parameter 0.05 Speed feedback (the default initially
displayed parameter) is now displayed on the upper line of the
display.
6. The display indicates as follows:
7. Close the Hardware enable contact.
8. The display indication changes as follows:
9. Close the RUN contact. The display indicates as follows:
If mechanical resonances occur when the motor is running, see
Testing the system in Specifying shaft stiffness and load inertia in
Appendix D Optimising the Dynamic Performance.
10. Press and hold down...
The motor speed increases in the forward direction. The upper line
of the display indicates an increasing value of speed in RPM.
Release the key when the display indicates a suitable value (eg.
100.0). The display nowindicates as follows:
11. Press and hold down...
The motor speed decreases to zero then increases in the reverse
direction. The upper line of the display indicates the speed with a
minus sign.
12. So far, the upper line of the display has been indicating the value of
speed feedback, which is the actual motor speed. If changes in
speed demand cause the Drive to enter current limiting or ramp
control occurs (by default ramps are disabled), the new value will be
displayed only when the motor has reached the new speed.
The following four steps will cause the value of the keypad (speed)
reference to be displayed, giving immediate indication of the value of
speed demand.
13. Press...
The display is now in Parameter mode, its lower line indicating 0.05.
14. Press and hold down...
... until 0.34 is displayed on the lower line. The upper line now
indicates the value of parameter 0.34 Keypad reference.
