This chapter lists various service jobs and explains their performance.
12.1
Replacing inverters
WARNING!
Electric shock hazard!
Risk of serious injury from contact with live parts!
Observe the 5 safety rules.
Note that dangerously high voltages can still be present in the inverter even 5 minutes after switching off
the power supply due to the residual charge of the DC link capacitors.
Ensure that the motor shaft is at a standstill before carrying out work. A rotating rotor can generate high
voltages at the terminals.
This chapter provides you with an introduction to the simple replacement of two inverters without additional
aids. Only the Paramodule from the replaced inverter must be used on the new inverter. In the Paramodule,
the action
A00 save values
stores the programming and the parameterization of the inverter safe from a power
failure.
The following conditions apply for the replacement:
•
The replacement inverter assumes the task of the inverter that is replaced. There is no change in the
drive-related task.
•
Inverters of the same device type are replaced.
•
The replacement inverter has the same or a higher hardware and software version as the inverter that
was replaced.
•
No projected devices or components (motor, rotary encoder, option boards, etc.) in the inverter are
changed.
Follow these steps:
Information
If inverters of different types are replaced or the devices to be configured on the inverter are
changed, the entire configuration must be changed with POSITool and checked!
Replacing the inverter
1. Start the
A00 save values
action. Wait until the action is complete with result
0:error free
.
2. Turn off the power supply voltage of the inverter. Wait until the display goes out.
