Warning!

 For floating networks remove 

screws at F1 and F2 on Frame sizes R5 or 
R6.

 9. Install the cable clamp(s) 

for the control cable(s). 
(Power/motor cables and 
clamps not shown in 
figure.)

Wiring the Controls

 1. Strip control cable sheathing 

and twist the copper screen 
into a pig-tail. 

 2. Route control cable(s) 

through clamp(s) and 
tighten clamp(s).

 3. Connect the ground screen 

pig-tail for digital and analog 
I/O cables at X1-1.

 4. Connect the ground screen 

pig-tail for RS485 cables at 
X1-28 or X1-32.

 5. Strip and connect the individual control wires to 

the drive terminals. For details, or other 
configurations, see “Control Connections” in 
the User’s Manual.

 6. Install the conduit/gland box cover (1 screw).

Check Installation

Before applying power, perform the following 
checks. 

Re-install the Cover

 1. Align the cover 

and slide it on.

 2. Tighten the 

captive screw.

 3. Re-install the 

control panel.

Apply Power

Always re-install the front cover before turning 
power on. 

Warning!

 The ACS550 will start up 

automatically at power up, if the external 
run command is on.

 1. Apply input power.

When power is applied to the ACS550, the 
green LED comes on.

Note!

  Before increasing motor speed, check that 

the motor is running in the desired direction.

Start-up

In Start-up, enter motor data (collected earlier) 
and, if needed, edit parameters that define how 
the drive operates and communicates.

Assistant Control Panel

The Start-up Assistant steps through typical 
start-up selections, and runs automatically 
upon the initial power up. At other times, use 
the steps below to run the Start-up Assistant.

 1. Use the MENU key to 

access the Menu list.

 2. Select Assistants.
 3. Select Start-up Assistant.
 4. Follow the screen 

instructions to configure 
the system. 

Note!

For common parameters and menu items, 
use the Help key 

 to display 

descriptions.
If you encounter Alarms or Faults, use the 
Help key or refer to the Diagnostic section 
of the User’s Manual.

Basic Control Panel

The Basic Control Panel does not 
include the Start-up Assistant. Refer 
to the Start-up Section of the User’s 
Manual and manually enter any 
parameter changes desired.
