Powering-up the 890CS
Initial Power-up Sequence
1. A three-phase supply is NOT necessary at this stage.
2. Before applying 3-phase power, ensure that an appropriate 3% line reactor has
been fitted. This is a pre-requisite of any input section.
3. Ensure ENABLE is low, (0V), X02/03 (connect a temporary switch or remove
terminal block).
4. Switch on the 24VDC auxiliary power supply to the 890CS drive. If daisy-chained
to the 890CD's, these will also power-up in Remote Mode and display a DCLO
trip (expected).
5. Check the voltage setting on the 890CS keypad (it will appear as soon as you
apply power) and ensure it matches your incoming line voltage. If not, switch off
the 24VDC, correct the setting of rotary voltage selector switch S1 then switch the
24VDC back on.
6. There are no parameters to set-up the 890CS unit.
7. Check that the run signal on each 890CD is inactive, unless motor rotation is
required at this time.
8. At this stage, apply 3-phase power to the 890CS. Changing ENABLE to high
(24V OUT), will cause the 890CS to power up the SSD_Rail.
9. Pressing the STOP key on each 890CD will clear the DCLO trip.
Normal Power-up Sequence
The simplest way to power up the 890CS is to connect the ENABLE input to 24V
OUT then power up the 3-phase power and the 24VDC auxiliary power supply
together. The 890CS will immediately power up the SSD_Rail.
Powering-up each 890CD
1. By now, the whole system has power applied to it.
2. The following sections cover getting the pertinent motor data, setting the
appropriate parameters (using the keypad) and performing an autotune.
890CD Set-up
Refer to Appendix A if using the 6511 keypad supplied with the drive. Appendix B contains information
about the 6901 keypad that displays menu and parameter names in English.
Motor Data
Before attempting to set up the drive, you will need some motor information. This is found on the
motor nameplate. The information you will need is listed below:
Base Volts Base RPM No load amps (mag current)
Base frequency Full load amps Connection (star or delta)
