7.4 Repair switch
Overview
The Repair switch allows the motor to be totally isolated from the Inverter. This means that
all power to the motor is terminated and the Inverter cannot start or stop the motor.
Stopping the motor
The motor must be stopped before activating the Repair switch. If the motor is not stopped
the Inverter may be damaged.
Discharge of Inverter
Wait at least five minutes to allow the unit to discharge after switching the Repair switch off
before carrying out any maintenance work.
Electrical safety
Regional installation and Safety Regulations regarding work on dangerous voltage
installation (e.g. EN50178) as well as relevant regulations regarding the correct use of tools
and personal equipment ( PPE ) still apply.
The location of the Repair switch is shown in the figure below.

Description
In the remote position the Inverter will use the command source and setpoint source set in
parameters P0700 and P1000 respectively. If the Inverter is part of an automated system, then it
will be under the control of the PLC.
In this position the Inverter will be in standby with pulses disabled and will ignore any command
source inputs. As the keyswitch is moved from this position a fault reset will occur.
In this position the Inverter ignores the command source and setpoint source set in parameters
P0700 and P1000 respectively. The Inverter will only react to the local buttons on the switch
cover.
The quickstop function enables the Inverter to react to sensors on a conveyor segment when
items move passed the sensor. The quickstop override button, disables the Inverters reaction to
the sensor signals.
This button toggles between inching and continuous movement of the motor. The movement of
the motor is determined by the values set in Parameters P1058 and P1061.
Inching: Press the Jog button to start the motor, and release the button to stop the motor.
Continuous: Press the Jog button to start the motor, and press the Jog button again to stop the
motor.
Pressing the Jog left button will move the conveyor belt to the left.
Pressing the Jog right button will move the conveyor belt to the right.
