Set the Speed Setpoints to zero so that the value of the SPEED SETPOINT parameter is
zero.
:
Verify that the MAIN CURR. LIMIT is set to 0.00%.
;
Apply the Start/Run command and check that 3-phase mains is applied to Power
Terminals L1, L2 and L3. Initiate "Enable" 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 8.1 or 8.2.
If the field voltage is not correct, make the following checks:
8.1
Internally Supplied Field:
•
Check that 3-phase is applied to terminals L1, L2 and L3
when the main contactor is closed.
•
Check that the 3 coding fuses on the power board are
healthy.
•
The FIELD ENABLE parameter should be set to ENABLE.
•
With the FIELD ENABLE parameter in view, press the
↓↓↓↓
(DOWN) key. The
display changes to FLD CTRL MODE IS. Press the M
key. Is this set to VOLTAGE CONTROL or
CURRENT CONTROL?
„
If set to VOLTAGE CONTROL, check the
value of the RATIO OUT/IN parameter. This
should be set to 90% maximum.
„
If set to CURRENT CONTROL, check the field current calibration set-
up, refer back to “Calibration”.
If the field volts are at maximum, check the field continuity. (The
field current may initially be lower than the rated value due to a
cold field.)
