7 START-UP PROCEDURE
If any problems or malfunctions occur during the start-up, refer to Chapter "Troubleshooting", to find out
the reason. All problems must be solved before continuing.
!
Warning! High voltages inside device. Wait for at least five minutes after the supply voltage
has been switched off before service actions. Display in operating condition (lights on)
indicates a dangerous voltage on the DC-bus. When display turns off, the DC-bus voltage is
about 100V. Note also that there is a dangerous voltage in the braking resistor always when
the DC-bus is charged.
#
Do not connect any voltage to the output terminals (U, V, W). Otherwise, the inverter will be
damaged.
#
The overload protection protects both the supply and the motor cables. The supply fuses provide
short circuit protection.
7.1 Visual checks
- Check condition of cubicles.
- Check that serial number of the drive is the same as in delivery documents.
- Check the cabling to braking resistor.
- Check the cabling to motor, brake, thermistors (and speed sensor).
- Check motor type.
- Check the wire terminations in the motor connection box
- Check connections for motor thermistors/ thermostat and brake wear.
- Disconnect motor (U, V, W) and brake cables to prevent damage of inverter. Measure insulation resistance of
brake coil and motor windings (each phase to ground).
- Re-connect motor and brake cables.
7.2 Checks before the first test run
- Check power supply voltage (nominal voltage +/- 10%).
- Check control voltage (nominal voltage +/- 10%).
- Make sure that run commands are off (pushbuttons / controller (master switch) at zero position).
- Turn on power from main switch and control voltage switch.
- Within about 1 second the control panel should have display.
- In a fault situation the red FAULT status indicator blinks and the display shows a fault code instead of
frequency.
- Check that green RUN status indicator is off.
- Check that external connections and selected control parameters are according to application.
7.3 Check motor parameters
In most of cases parameters are properly set after factory tests and no adjustments are needed except
for the parameters that depend on application. In case the factory has not had information about the
motors, motor related parameters need to be adjusted with the following steps. Write down on the
parameter list all the values that have been changed and at the end save parameters to User
parameters, see Chapter "User parameters".
