2 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.
−
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 fuses of the supply
provide short circuit protection.
Visual checks
–
Record all checks and results.
–
Check condition of the cubicles.
–
Check that XT Drive serial number is the same as in the delivery documents.
−
Check the switch settings on SSU.
−
If necessary, open the control box cover and adjust the SSU settings.
−
Check the cabling to the motor, brake, thermistors and speed sensor.
−
Check the motor type.
−
Check the wire terminations in the motor connection box
−
Check connections for motor, thermistors, heaters, brake wear and speed sensor circuits.
−
Disconnect motor (U, V, W) and brake cables to prevent damage of the inverter. Measure the
isolation resistance of the brake coil and the 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.
Checks before the first test run
Warning! High voltages inside the device.
−
Check the power supply voltage (nominal voltage +/- 10%).
–
Make sure that run commands are off (pushbuttons / controller (master switch) at zero position).
−
Turn on the power from the main switch and the control voltage switch.
– Within about 1 second the keypad should display "AC on", and then in about 1 second the
display changes to the motor output frequency "0.00" and the 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 the green RUN status indicator is off.
−
Check that the external connections and programming of digital inputs are according to the
application.
−
The parameters are properly set after factory tests and no adjustments are needed except for
the parameters that depend on the application and the motor. Write down in the parameter list
all the values that have been changed.
Warning! High voltages inside the device. Wait for at least five minutes after the supply
voltage has been switched off before doing any service actions. The display in
the operating condition (lights on) indicates a dangerous voltage on the DC-bus.
When display turns off, the DC-bus voltage is approximately 100V. Note also that
there is always a dangerous voltage in the braking resistor when the DC-bus is
charged.
