Action
Check the voltage range setting in parameter 195.01 Supply voltage.
For more information on setting up the supply control program, see the ACS880 IGBT supply control
program firmware manual (3AUA0000131562 [English]).
For more information on setting up the Optimal grid control mode, see Optimal grid control of ACS880
IGBT supply control program supplement (3AXD50000164745 [English]).
For more information on setting up the distributed I/O bus, see ACS880 distributed I/O bus supplement
(3AXD50000126880 [English]).
If you need more information on the use of the control panel, see the ACX-AP-x Assistant control
panels user's manual (3AUA0000085685 [English]).
Drives with a fieldbus adapter module (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]). Check that the
communication works between the drive and the PLC.
Make sure that the control panel [A51] is in the remote mode (Loc/Rem key of the panel). Otherwise
no external control (operating switch on the cabinet door, or fieldbus adapter) is possible.
Powering up the main circuit of the drive
Drive with the grounding switch ([Q9] , option +F259): Open the grounding switch.
Drives with a DC switch-disconnector ([Q11] option +F286): Make sure that all DC switch-disconnectors
[Q11] are closed and charging switches [Q10] are open in all IGBT supply module cubicles. See also
Additional instructions for closing the DC switch-disconnector (page
• Drives with a main switch-disconnector ([Q1,], option +F253): Close the main switch-disconnector.
• Drives with a main breaker ([Q1], option +F255): Crank the main breaker in.
WARNING! Do not use excessive force. Check the inter-lockings if you cannot close the dis-
connecting device. See the delivery-specific circuit diagrams.
Close the charging disconnector [Q3] and the DC switch-disconnector for line-up charging [Q40] (if
present).
Turn the operating switch [S21] to the ON (1) position to activate the run enable signal. The main con-
tactor or breaker closes. If this is not the case, use possible additional main contactor/breaker control
signal(s) to close it. See the delivery-specific circuit diagrams and the supply unit firmware manual.
On-load checks
Validate the operation of safety functions if any (for example, emergency stop). See the delivery-spe-
cific circuit diagrams and function-specific manuals.
Drives with an emergency stop circuit (options +Q951, +Q952, +Q963, +Q964, +Q978, +Q979): Test
and validate the operation of the emergency-stop circuit. See the delivery specific circuit diagrams and
wiring, start-up and operating instructions of the option.
