Setting Up The Supply Unit Parameters; Powering Up The Main Circuit Of The Drive; On-Load Checks - ABB ACS880-207 Hardware Manual

Tasks

Setting up the supply unit parameters

Check the correct voltage range, parameter 195.01 Supply voltage.
If your supply unit consists of more than one module, parameters 195.30 Parallel type filter and
195.31 Parallel connection rating id need to be set. First, select the correct voltage range with
parameter 195.30 Parallel type filter. Then, select the correct supply unit type with parameter 195.31
Parallel connection rating id.

If you need more information on the use of the control panel, see ACS-AP-x assistant control panels
user's manual (3AUA0000085685 [English]).
Switch the control panel to the remote mode (Loc/Rem key) to enable control of the supply unit with
the operating switch [S21].
Drives with a fieldbus adapter (optional): Set the fieldbus parameters. Activate the fieldbus adapter
module in the control program. See the user's manual of the fieldbus adapter module, and ACS880
IGBT supply control program firmware manual (3AUA0000131562 [English]).

Powering up the main circuit of the drive

Switch the main switch-disconnector/air circuit breaker [Q1] on. Note: The grounding switch [Q9]
(option +F259) must be switched off.
Switch the charging circuit switch fuse [Q3] on.
Turn the operating switch [S21] to on (1) position to activate the Run enable signal of the supply unit.
Now, the supply unit starts and the control program steps through the power-up sequence:
1. charging contactor [Q4] switch on, 2. charging (until the DC link voltage rises high enough), 3.
main contactor [Q2] switch on, 4. start of the supply module rectifying, 5. charging contactor [Q4]
switch off.
Note: The supply unit charges the DC link before it starts rectifying and supplying the inverter units.

On-load checks

Check that the supply module cooling fan and LCL filter module fans rotate freely in the right
direction. A paper sheet set on the intake (door) gratings stays. The fans run noiselessly.
Validate the operation of safety functions (for example, emergency stop).
WARNING! The safety functions are not safe before they are validated according to the
instructions. Safety functions are optional. See the function-specific manual for the
validation tasks.
