4-6 Operating the Converter
590 Series DC Digital Converter
5 With the Program Stop and Coast Stop LEDs illuminated:
• Apply the "Start/Run" command to C3.
The main 3-phase contactor should pull-in and remain energised, (it may de-energise
almost immediately due to the 3-phase fail alarm).
• Remove the "Start/Run" command from C3.
The main 3-phase contactor should drop-out and remain de-energised.
If the above sequence does not function, remove the auxiliary power and check start/stop
sequencing and contactor wiring.
If the contactor is left energised for an extended time during this check, the controller will detect
that 3-phase is not connected and switch off the contactor, flagging the 3-phase alarm.
The main contactor should never be operated by any means other than the drive internal
controls, nor should any additional circuitry be placed around the contactor coil circuit.
WARNING!
Only continue with the set-up instructions if the stop/start circuits and contactor
operate correctly.
6 Switch off all power supplies to the equipment and, when the whole system is totally
isolated and safe, re-connect the main 3-phase power supply.
• Switch on the auxiliary supply.
• Switch on the main 3-phase supply.
MAIN & AUXILIARY POWER ARE CONNECTED AT THIS STAGE
7 Set the Speed Setpoints to zero so that the value of the SPEED SETPOINT parameter
is zero, this is also output at Terminal A8.
8 Verify that the MAIN CURR. LIMIT is set to 0.00%, or that the ANIN 5 (A6)
parameter in the DIAGNOSTICS menu at level 1 is displaying 0.00V.
9 Apply the Start/Run command and check that 3-phase mains is applied to Power
Terminals L1, L2 and L3. Initiate "Enable" (C5) and immediately check that the correct field
voltage appears between Terminals D4 and D3.
This is high voltage DC, proceed with caution. Do not continue if this is incorrect, switch
off all supplies and check connections. Refer to 9.1 or 9.2 on the next page:
