CHAPTER 5 - START-UP
NOTE!
The last speed reference value set via key and
keys
is saved.
If you wish to change this value beforeenabling of inverter,
change the value of the parameter P121 - Keypad
Reference.
The self-tuning routine can be cancelled by pressing the
key.
NOTES!
(1)
If during the running of theSelf-Tuning Routinethe display
shows E14,
this means that the motor parameters were
not acquired correctly by the inverter. The most common
reason for this fault may be that the motor has not been
coupled to the inverter output. However motors with very
lower currents than the used inverter, or incorrect motor
connection may also cause the fault E14. In this case,
operate the inverter in V/F mode (P202 = 0). When the
motor is not connected and the fault condition
E14
is
indicated, proceed as follows:
Switch off the inverter. Wait at least10 minutes to allow
a complete discharge of the capacitors.
Connect the motor to the inverter output.

Motor accelerates up to 90 rpm (for IV
pole motor - minimum speed) in CW
direction of rotation

Motor accelerates up to 1980 rpm (for
IV pole motor - maximum speed)
Motor decelerates

to 0 rpm and
then reverses the direction of rotation

CCW,
accelerating back to
1980 rpm
Motor decelerates down to 0 rpm
Motor accelerates from 0 rpm up to the
JOG speed set at P122
Ex:
P122 = 5.00 Hz that corresponds
to 150 rpm for IV-pole motor
Reverse (CCW) direction of rotation
Motor decelerates down to 0 rpm
