4.3.1.1 - Quick start procedure in Sensorless mode
The quick start is suitable for Sensorless control with the following limitations:
Starting torque (0 to 10% of rated speed) 75% of rated torque
Maximum load/motor inertia ratio 80 (*)
Minimum application rated speed 1/10 of rated speed
If the ratio between the load inertia and the motor inertia is more than 80, set 03.38 = "Software 4/flux oriented" in the advanced menus
A
Drive auto test sequence
1- Drive off, check that:
▪ STO1 and STO2 terminals are connected to +24V terminal
▪ Run command is connected but not enabled
▪ Motor is connected to U, V and W. If phases are not crossed between drive and motor, motor will
run clockwise looking at DE when run forward is enabled. If not appropriate use parameter Ctr.12
of advanced menu to reverse rather than crossing cables
3- Set the HMI clock according to procedure detailed in paragraph 2.2.3.5
4- Open STO1 and STO2 to disable the drive during drive setting
Control Mode selection
1- In " Parameter setting " mode, select " Quick Set up " mode
2- Set
Ctr.01
= "Centrifugal application" to select application (suitable for constant torque application also).
At the end of the sequence, parameter is automatically set back to "Disabled"
If Induction Motor
1 - Set
Ctr.02
(control mode) = "Induction motor in open
loop mode (#)"
3 - Set
Ctr.14
(Autotune mode) = "Stationary: motor
data completed"
Motor parameters from nameplate Motor parameters from nameplate
Warning : Parameters must be entered as shown on
nameplate (including decimals).
2 - Check
Ctr.03
(switching frequency) = value shown
on motor nameplate "minFsw" (note 1)
2 - Set Ctr.03 (switching frequency) =
value shown on motor nameplate "minFsw" (note 1)
• Mtr.01 (Motor rated Frequency) (Hz)
•
Mtr.02
(Motor rated current) (Amps)
• Mtr.03 (Motor rated speed) (rpm)
•
Mtr.04
(Motor rated voltage) (V)
•
Mtr.06
(Drive terminal) for PTC validation if fitted
• Mtr.08 (Transient inductance Ld) (mH)
•
Mtr.09
(Motor volt per 1000 rpm) (V/rpm)
1 - Set Ctr.02 (control mode) = "PM motor (Servo) in
vector control mode"
3 - Set Ctr.14 (Autotune mode) = "Stationary:
motor data completed"
If Permanent Magnet Motor
• Mtr.01 (Motor rated Frequency) (Hz)
•
Mtr.02
(Motor rated current) (Amps)
• Mtr.03 (Motor rated speed) (rpm)
•
Mtr.04
(Motor rated voltage) (V)
•
Mtr.06
(Drive terminal) for PTC validation if fitted
2 - Switch the drive power supply ON:
▪ The test is automatically performed during power up (5 sec sequence)
▪ At the end of the test:

If the test passed, the HMI displays "Ready" and the drive is ready to use

if a "Diagnostic" trip appears, read the result of the power module test in 17.06 ,
and then get in touch with your usual contact
