7) Possible failures:
If no failure occurred, go to step 8. Otherwise, check the drive connections paying
particular attention to supply voltages, DC link and input reference. Also check if
alarm messages are displayed. In the MEASURES MENU
, check the reference
speed (M001), the supply voltage to the control section (M030
), the DC link voltage
(M029), and the condition of control terminals (M033
). Check to see if these
readouts match with the measured values.
8) Additional parameter
modifications:
When parameter P003 = Standby Only (condition required for changing C
parameters), you can change Cxxx
parameters in the CONFIGURATION menu only
when the drive is DISABLED or STOPPED, whereas if P003
= Standby + Fluxing,
you can change Cxxx
parameters when the motor is stopped but the drive is
enabled.
You can
write down any custom parameters in the table provided on the last pages
of this Programming Guide (CUSTOM PARAMETERS).
9) Reset:
If an alarm trips, find the cause responsible for the alarm and reset the drive. Enable
input MDI3 (terminal 16) for some time, or press the RESET key
on the
display/keypad.
NOTE
When the IFD control algorithm is used, only speed references can be set up.
NOTE
The ENABLE-A and ENABLE-B inputs are allocated to the STO function. If this
safety functionality is to be adopted, the control mode and the control circuit of these
signals must be accomplished as per the
Safe Torque Off Function - Application
Manual.
That manual also includes a detailed
validation procedure of the control
configuration of the STO function to be executed upon first start-
up and also
periodically at yearly intervals.
