4 - COMMISSIONING FOR CONTROL OF AN LSRPM MOTOR IN «SENSORLESS»
MODE (PARAMETER 00.14)
• Terminals SDI1 and SDI2 are connected in order to run the power self-test (see
17.03
).
• The run command has not been enabled.
• The motor is connected.
Drive off, check that:
• In read mode, the operating status displays “DISABLED”.
• If the drive trips, refer to section 7 “TRIPS – DIAGNOSTICS” in the manual ref.3871.
Switch on the drive
• In parameter setting mode, select “Basic set up”.
• Return to factory setting
00.45
= 50 Hz High or Low for a 400V/50Hz supply, or 60 Hz High or Low for a 460V/60Hz supply
(
00.45
automatically returns to DISABLED after few seconds).
• Enter
00.13
= SERVO and
00.14
= SENSORLESS 2.
Select the control mode
•
00.02
: MAXIMUM SPEED (in rpm).
•
00.03
and
00.04
: ACCELERATION RATE 1 and DECELERATION RATE 1
(in sec for 1000 rpm, factory setting).
•
Connect the motor thermistor to the drive terminal block (ADI3/0V terminals),
and set
00.28
= CTP (1).
Enter the main parameters
•
00.06
: MOTOR RATED CURRENT (A).
•
00.07
: MOTOR RATED SPEED (rpm).
•
00.08
: MOTOR RATED VOLTAGE (V).
•
00.10
: MOTOR RATED FREQUENCY (Hz).
•
05.24
: Enter 80% of plated transient inductance Ld.
•
05.33
: Enter EMF at 1000 rpm (plated).
Motor parameters to be taken from the nameplate
Set the other control parameters
•
Before setting the maximum speed,
check that the motor and the machine
can withstand it.
• Respect the supply voltage “Inverter
supply” indicated on the motor nameplate.
The drive is ready to operate or waiting for additional parameter settings.
•
00.12
: The SWITCHING FREQUENCY value must be set according to the following table :
•
00.21
: CURRENT LOOP PROPORTIONAL GAIN =
κ
x kVA x Ld
with:
-
κ
= 1 for 400/460V drives,
- kVA : Drive rating (example : 340 for a 340T),
- Ld : inductance value located on the motor nameplate in mH.
We advise that the gain value should not be greater than 80 when the stator frequency is lower than 150 Hz.
