Start-up 147Switch on the auxiliary voltage [Q21].Drives of frame size 1×R8i + 1×R8i: Close the main switch-disconnector [Q1.1]. This will power upthe main circuit of the drive as well as the auxiliary voltage circuit.Setting up the supply unit parametersCheck the voltage range setting in parameter 195.01 Supply voltage.For more information on setting up the supply control program, see the ACS880 IGBT supply controlprogram firmware manual (3AUA0000131562 [English]).If you need more information on the use of the control panel, see ACX-AP-x Assistant control panelsuser's manual (3AUA0000085685 [English]).Setting up the inverter unit parameters, and performing the first startSet up the inverter control program. See the appropriate start-up guide and/or firmware manual.There is a separate start-up guide only for some control programs.Check that parameter 95.09 Fuse switch control is disabled.Drives with a brake chopper (option +D150): Refer also to chapter Resistor braking, section Start-up(page 256).Drives with a sine output filter (option +E206): Check that bit 1 of parameter 95.15 Special HWsettings is activated.Drives with a fieldbus adapter module (optional): Set the fieldbus parameters. Activate theappropriate assistant (if present) in the control program, or see the user’s manual of the fieldbusadapter module, and the drive firmware manual.Check that the communication works between the drive and the PLC.Drives with an encoder interface module (optional): Set the encoder parameters. Activate theappropriate assistant (if present) in the control program, or see the user’s manual of the encoderinterface module, and the drive firmware manual.Powering up the main circuit of the driveSwitch off the grounding switch [Q9.1] (option +F259).Close the main switch-disconnector [Q1.1] or main breaker [Q1]. (With frame size 1×R8i + 1×R8i, thishas already been done to power up the auxiliary circuit.)Note: Do not use excessive force. The main switch-disconnector (or main breaker) can only beclosed when• the main input terminals (L1, L2, L3) are powered, and• auxiliary voltage is switched on [Q21], and• grounding switch is off [Q9.1] (option +F259).Close the charging switch [Q3]. This will enable the pre-charging of the DC capacitors of the drive.The charging itself is controlled by the supply control unit [A51].Turn the operating switch [S21] to the ON (1) position to activate the run enable signal for the supplyunit. Depending on control source settings, this may also close the main contactor (if present). If amain contactor is present and does not close, refer to the circuit diagrams delivered by the drive aswell as the appropriate firmware manuals.On-load checksStart the motor to perform the ID run.Check that the cooling fans rotate freely in the right direction, and the air flows upwards.Check that the motor starts, stops and follows the speed reference in the correct direction whencontrolled with the control panel.Action
