12 Quick start-up guide
Start-up procedure
You can operate the drive locally from Drive composer or from the ACS880 control
panel.
The following steps describe the actions that is necessary when powering up the
drive for the first time in a new installation (for example, entering the motor data).
After the start-up, the drive can be powered up without using these start-up functions.
You can repeat the start-up procedure when you change the data.
In there is a fault, refer to chapter Fault tracing on page 45.
Safety
WARNING! Obey all safety instructions for the drive. Only qualified electricians are
allowed to start up the drive.
Settings
Switch on the HT isolator and the charge feedback transformer.
See SPRS connection diagram on page 17.
Check the voltage at the incoming panel.
The voltage should be equal to the secondary voltage of feedback transformer.
Switch on the ISU and check the DC bar voltage in ISU CDP.
The DC bus voltage should be 1.1 · sqrt(2) · Vac (secondary voltage).
Check the DI status of the inverter and SPRS RMIO as per the configuration.
See SPRS connection diagram on page 17.
Check the rotor speed.
The rotor speed should be within the specified limit.
See parameters 78.01 SPRS max speed % and 78.02 SPRS min speed %.
Release the emergency stop button on the panel and check if inverter and SPRS are
ready for operation. Using selector, switch from GRR to SPRS mode.
After SPRS RMIO receives synchronization acknowledgment from RSYNC card the
changeover takes place from GRR/LRS to SPRS.
See SPRS connection diagram on page 17.
Make sure the SPRS is aligned with the connection diagram.
See SPRS connection diagram on page 17.
