Initial Start-Up Routines
WARNING
Unpredictable motion, especially if motor parameters are incorrect.
Ensure no personnel are in the vicinity of the motor or any connected machinery.
Ensure that no machinery connected to the motor will be damaged by unpredictable motion.
Ensure that the emergency stop circuits function correctly before running the motor for the first time.
The Routines 1 & 2 below will run the drive in the default V/F fluxing control mode (VOLTS / HZ) to
begin with using either the Keypad or the Control Terminals.
The 890CS Common Bus Supply must be supplying DC to the 890CD Common Bus Drive(s). This is
indicated by the red LEDs displaying at the front of the busbar terminal boxes on the top of the units.
Routine 1: Local Mode
Note
Refer to Chapter 8: “The Keypad” to familiarise yourself with the keypad and menu structure.
Local control has a use for commissioning a drive. It is not the expected way to operate a system drive.
On the 890CD Common Bus Drive's keypad:
1.
Select Local Mode (refer to Chapter 8: "The Keypad" for details).
2.
The drive should be "healthy" now it is powered-up: no flashing trip messages displayed, and the 6901
keypad's HEALTH LED is lit (the RUN LED remains off). The keypad will display the Remote Setpoint
parameter.
If the drive has tripped, the keypad will be flashing a trip message, and the 6901 keypad's HEALTH
LED will flash. Refer to Chapter 10: “Trips and Fault Finding” to investigate and remove the cause of
the trip.
