Using Quick Start 5-7
5.4.3 Exiting Before Self-Tuning is Complete
If you have not yet pressed to start self-tuning, you can stop self-tuning (and
Quick Start) by pressing . The Main Menu is displayed if you enabled self-tuning
in Quick Start, or the Self Tune Parameters menu.
If you have already pressed to start self-tuning, press or assert the stop
input to stop self-tuning. This causes a self-tuning drive fault. See the next section for
information on these faults.
5.4.4 What To Do if a Fault Occurs During Self-Tuning
If a fault occurs during self-tuning:
• the motor coasts-to-rest, regardless of the setting of STOP MODE SELECT (P.114).
• the drive logs a self-tuning fault, which must be reset and cleared. See chapter 7 for
information on clearing and resetting faults.
When the problem that caused the fault is corrected, repeat the self-tuning procedure.
5.4.5 Self-Tune Parameter Descriptions
Configure these parameters before starting the process described in section 5.4,
“Self-Tuning the Current Minor and Speed Loops”.
Low values increase the speed loop response. High values decrease the speed
response, but result in more stability. The typical value is 25. Applies to speed loop
tuning only.
SELF TUNE BRIDGE
(P.220)
Determines the
direction the motor
shaft will rotate
during the speed loop
self-tune process by
selecting the
SCR
bridge.
Parameter Range: FORWARD
REVERSE
Default Setting: FORWARD
Parameter Type: Tunable
If the reverse bridge will be predominant in the application, select REVERSE .
For non-regenerative (S6) drives, this is fixed to FORWARD .
SELF TUNE STABILITY (P.219)
Determines the
self-tune stability,
which configures the
performance of the
speed loop. Parameter Range: 10 to 100
Default Setting: 25
Parameter Type: Tunable
