3.6 ISOLATE THE DRIVE
using branch circuit protection
or circuit breaker (
8
).
Install the 3-phase fuses (
6
).
Re-instate branch circuit protection or circuit breaker
(
8
)
3.7
Select Local Control on the
Keypad. Refer back to
3.4
for
how to do this.
This will display the local
speed setpoint: 0.00%.
FORWARD
REF: 0.00 %
IMPORTANT
Do not change any of the previously made calibration settings once the main contactor is energised.
MAIN & AUXILIARY POWER ARE CONNECTED AT THIS STAGE
3.8
Use a Voltmeter that conforms to IEC 61010 (CAT III or higher).
Press the Start key
on the Keypad
Ensure that "Enable" (C5) is ON.
Check that 3-phase mains is applied to the power terminals L1, L2 and L3.
Check the correct field voltage appears between the field output terminals F+ and F-.
If the Field Voltage is
incorrect do not continue.
Switch off all supplies and
check connections.
This is high voltage DC.
Proceed with caution.
3.9
Check that the
OK
(Health) and
(Start key) LEDs on the Keypad are now lit, indicating that the motor is capable
of rotating.
Also, either the
►(forward) or ◄ (reverse) led will be lit, indicating the direction of rotation.
STOP
At 20% setpoint:
The 590PR drive (4Q)
can stop in approximately 2
seconds (the drive decelerates the motor to zero
speed at a rate determined by the STOP TIME and
MAIN CURR.LIMIT parameter values).
The 591PR drive (2Q)
can coast stop.
START
The drive can run
provided that:
B8 & B9 are TRUE (+24V)
C5 is ON (+24V)
