5.3.1 Start-up -
Operation via Keypad
(HMI) - Type of Control:
Linear V/F (P202 = 0)
ACTION
Power-up the inverter
Press the key
Press the key and hold it
depressed until 60 Hz is reached
Press the key
Press the key
Press the key and hold it
depressed
Release the key
(*) 90 rpm for 4 pole motor.
(**) 1800 rpm for 4 pole motor.
The sequence below is valid for the connection 1 (refer to item
3.2.6). Inverter must be already installed and powered up
according to chapter 3 and item 5.2.
Connections according to figure 3.6.

NOTE!
The last frequency reference (speed) value set via the
and keys is saved.
If you wish to change this value before inverter enabling, change
parameter P121 - Keypad Reference.
NOTES!
(1) If the direction of rotation of the motor is not correct, switch off
the inverter. Wait at least for 10 minutes to allow complete
capacitor discharge and then swap any two wires at the mo-
tor output.
(2) If the acceleration current becomes too high, mainly at low
frequencies, set the torque boost (IxR compensation) at P136.
Increase/decrease the content of P136 gradually until you
obtain an operation with constant current over the entire
frequencyrange.
(3) If E01 fault occurs during deceleration, increase the
deceleration time at P101 / P103.
CHAPTER 5 - START-UP
DESCRIPTION
Inverter is ready to be operated
Motor accelerates from 0 Hz to 3 Hz
(minimum frequency), in the forward (CW)
(1)
direction of rotation
Motor accelerates up to 60 Hz
(3)
Motor decelerates down to 0 rpm and
then reverses the direction of rotation
CWCCW accelerating back to 60 Hz
Motor decelerates down to 0 rpm
Motor accelerates up to JOG frequency
given by P122. Ex: P122 = 5.00 Hz
Reverse (CCW)
Motor decelerates down to 0 rpm
