9.4 Repair switch
The location of the repair switch on the wall-mounted converter is shown in the figure below.

Function description
When the repair switch is set to OFF, the mains power to the converter is terminated. The
converter pulses are disabled and the motor cannot be started or react in anyway to
commands from the converter or the controlling PLC. In this case, F07802 will be generated
with ON command.
With parameter r8559.12, you can read the feedback signal of the repair switch:
• r8559.12 = 1, repair switch is switched to OFF
• r8559.12 = 0, repair switch is switched to ON (mains on or no repair switch installed)
The repair switch can be padlocked into position so that once it has been switched off, it
cannot be accidentally switched on.
The motor can be repaired or replaced as required. Once the repair has been completed the
repair switch can be unlocked and switched on - the motor is then directly under the
command of the converter or the controlling PLC.
It should be noted that although the motor is isolated, communications and commands can
be passed between the controlling PLC and the converter, for example, parameters can be
changed.
