8 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.
m
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.
m
Do not connect any voltage to the output terminals (U, V, W). Otherwise, the inverter will be damaged.
m
The overload protection protects both the supply and the motor cables. The fuses of the supply provide short
circuit protection.
2.15 Visual checks
- Check condition of cubicles.
- Check that serial number of the drive is the same as in delivery documents.
- Check the switch settings on SSU (see Chapter “Speed Supervision Settings”)
- If necessary, open the control box cover and adjust the SSU settings.
- 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, brake wear and speed sensor circuits.
- 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.
- Check braking resistor(s).
- Terminals X1:21-27 and X1:51-57 are for electronics level signals.
- Normally only shielded wires are connected to these terminals. Check that no control or line voltage level wires are
connected there.
2.16 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 display "AC on", and then in about 1 second the display changes to
motor output frequency "0.00" and green READY status indicator turns on.
- 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 method are according to application.
- Parameters are properly set after factory tests and no adjustments are needed except for the parameters that
depend on application. 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”.
2.17 Test run without load
- Make sure that movement will not cause any danger to the environment or to the crane itself. Avoid driving close to
the limit areas.
- Check limit switches manually if possible.
- Check the run commands on display panel and correct the drum rotating direction. The arrow rotates clockwise if S1
is applied and counter-clockwise if S2 is applied.
- Check the function of the speed sensor, see chapter “Speed sensors”
- Check the function of the speed supervision circuit. See chapter "Functional test drive for SSU".
- Drive direction S1 at minimum speed for 5 to 10 seconds. Accelerate to full speed. Run 5 to 10 seconds. Stop.
Repeat the same in direction S2. Check the frequency display to make sure that the frequency changes through the
whole operational frequency range from minimum to nominal speed.
