AC890PX AC Drive
Routine 2: Remote Mode
This routine assumes that the drive’s control terminals are wired as shown in "Full Connection Diagram" on page 3-18.
IMPORTANT
Ensure that the speed potentiometer is set to zero.
On the AC890PX AC Drive:
1.
The drive should be "healthy" now it is powered-up: no flashing trip messages displayed, and the keypad's HEALTH LED
is lit (the RUN LED remains off).
If the drive has tripped, the keypad will be flashing a trip message, and the keypad's HEALTH LED will flash. Refer to
Chapter 8: “Trips and Fault Finding” to investigate and remove the cause of the trip.
2. Select Remote Mode - refer to Chapter 6: "The Keypad" for details, or power-down and power up the unit to re-initialise
in Remote mode.
3. To Start in Remote Mode, close the "Run" switch on your control panel (applying 24V to DIN2, terminal X15/02 -
RUN).
4. Turn the speed potentiometer up a little to apply a small speed setpoint (applying a variable voltage to AIN3, terminal
X12/04 - REMOTE SETPOINT). The keypad's RUN LED will light and the motor will rotate slowly (the RUN LED will
flash if the setpoint is at zero).
Reverse the motor’s direction of rotation either by pressing the
W X
key on the keypad, or by swapping two of the motor
phases ( WARNING: Disconnect the mains supply first ).
5. To Stop in Remote Mode, open the "Run" switch on your control panel (removing 24V from DIN2, terminal X15/02 -
RUN).
